A guide to fertility

Adequate levels of vitamin B12 are important for both male and female fertility as it helps in the production of healthy sperm and eggs. Deficiency of vitamin B12 can cause low sperm count, decreased sperm motility, and ovulatory dysfunction in females.

AMH (Anti-Müllerian hormone) is a hormone produced by the cells in the ovary that are responsible for developing follicles, which are structures that contain eggs. In males, AMH is produced by the Sertoli cells in the testes.

In females, the level of AMH in the blood is a marker of the number of follicles in the ovaries, which can be an indicator of ovarian reserve, or the number of eggs a woman has left in her ovaries. Women with higher AMH levels tend to have more follicles and eggs, while women with lower AMH levels may have fewer eggs and a reduced ovarian reserve. This can potentially affect their ability to conceive.

In males, AMH plays a role in the development of the male reproductive system during fetal development. After puberty, the level of AMH in males drops significantly and remains low throughout adulthood.

When conducting a fertility hormone test, it’s crucial to evaluate various parameters, including corrected calcium levels. Adequate calcium is necessary for optimal reproductive health in both males and females, as it supports proper sperm function in men and normal foetal development during pregnancy. However, elevated calcium levels in the blood (hypercalcemia) can negatively impact fertility in both sexes. Thus, assessing corrected calcium levels is an important part of fertility testing.

A complete blood count (CBC), which includes measurements of both white blood cells and red blood cells, can provide important information about a person’s overall health and potential fertility.

Red blood cells carry oxygen to the body’s tissues and organs, including the reproductive system. Anemia, a condition in which the body doesn’t have enough red blood cells or hemoglobin, can lead to fatigue and other health issues that can impact fertility. By measuring red blood cell count and hemoglobin levels, a CBC can detect the presence of anemia or other red blood cell disorders that may be affecting fertility.

White blood cells play an important role in the body’s immune system, helping to fight off infections and diseases. Elevated levels of white blood cells may indicate the presence of an infection, inflammation, or an autoimmune disorder that could potentially impact fertility.

Overall, a CBC provides valuable insight into a person’s overall health, including their reproductive health. By identifying any potential issues with red or white blood cell counts, individuals can take proactive steps to address these issues and improve their chances of conceiving.

Cortisol is a hormone that plays a critical role in regulating the body’s stress response. When the body experiences stress, cortisol levels rise to prepare the body for a fight-or-flight response. However, prolonged or chronic stress can lead to elevated cortisol levels, which can have negative effects on reproductive function in both males and females.

When trying to conceive, it’s essential to evaluate various parameters, including cortisol levels, as elevated levels of cortisol can lead to reproductive dysfunction. In females, high cortisol levels can cause irregular menstrual cycles and ovulatory dysfunction, while in males, it can lead to decreased testosterone production and poor sperm quality. Thus, testing for cortisol levels can provide valuable information about the potential impact of stress on reproductive health, allowing couples to make informed decisions about their fertility.

Testing for ferritin, a protein that stores iron, is recommended when trying to conceive because iron plays a vital role in reproductive health. Iron is essential for the formation of healthy eggs and sperm and is also involved in the development of the placenta during pregnancy. Low levels of iron can lead to anemia, a condition that can negatively impact fertility in both males and females.

In women, low iron levels can cause irregular menstrual cycles and disrupt ovulation. Iron deficiency can also lead to a condition known as hypochromic microcytic anemia, which can increase the risk of preterm labor, low birth weight, and other pregnancy complications. In men, iron deficiency can impair sperm production and lead to poor sperm quality.

Therefore, testing for ferritin levels is an important part of fertility testing, as it allows you to identify and address any potential iron deficiencies that could be affecting your ability to conceive. 

Follicle-stimulating hormone (FSH) is a hormone produced by the pituitary gland that plays a crucial role in reproductive function. When trying to conceive, it’s essential to test for FSH levels as they can provide valuable information about ovarian reserve and potential fertility issues.

In women, FSH stimulates the growth and development of ovarian follicles, which contain immature eggs. Therefore, high levels of FSH can indicate decreased ovarian reserve or a reduced number of eggs remaining in the ovaries. This can make it more challenging to conceive, as fewer eggs are available for fertilisation. High FSH levels can also indicate early menopause, which can impact fertility.

In men, FSH stimulates the production of sperm in the testicles. High levels of FSH in men can indicate decreased sperm production or poor sperm quality, which can reduce fertility.  Therefore, testing for FSH levels is an essential component of fertility testing, as it can help identify potential fertility issues in both males and females, allowing for early intervention and treatment to improve the chances of successful conception.

Testing for free thyroxine (T3) and free thyroxine (T4) is recommended when trying to conceive because thyroid hormones play a critical role in reproductive health. These hormones are produced by the thyroid gland and are involved in regulating metabolism and other bodily functions.

In women, thyroid hormones are essential for the development and maturation of ovarian follicles, as well as the production of estrogen. Therefore, imbalances in thyroid hormone levels can lead to fertility issues such as irregular menstrual cycles, ovulatory dysfunction, and infertility. Thyroid hormone imbalances can also increase the risk of miscarriage and other pregnancy complications.

In men, thyroid hormones are involved in the development and maturation of sperm. Imbalances in thyroid hormone levels can lead to decreased sperm production or poor sperm quality, which can reduce fertility.

Therefore, testing for free T3 and free T4 levels is an important aspect of fertility testing, as it can help identify potential thyroid hormone imbalances that could be affecting reproductive health. Early detection and treatment of thyroid hormone imbalances can improve the chances of successful conception and a healthy pregnancy.

Testing for Hemoglobin A1c (HbA1c) is recommended when trying to conceive because it can provide valuable information about blood sugar control and the risk of developing diabetes. High levels of HbA1c indicate poor blood sugar control over the previous 2-3 months and can indicate a higher risk of developing diabetes.

In women, high blood sugar levels can lead to fertility issues such as irregular menstrual cycles, ovulatory dysfunction, and infertility. High blood sugar levels can also increase the risk of pregnancy complications such as gestational diabetes, pre-eclampsia, and preterm labor.

In men, high blood sugar levels can impair sperm function and reduce fertility.

Therefore, testing for HbA1c levels is an important aspect of fertility testing, as it can help identify potential blood sugar imbalances that could be affecting reproductive health. Early detection and treatment of high blood sugar levels can reduce the risk of fertility issues and pregnancy complications, improving the chances of successful conception and a healthy pregnancy.

Testing for High-density lipoprotein (HDL) and HDL ratio is recommended when trying to conceive because they are indicators of cardiovascular health, which can affect reproductive health. HDL is known as the “good” cholesterol because it helps to remove low-density lipoprotein (LDL) or “bad” cholesterol from the bloodstream.

In women, high levels of LDL and low levels of HDL have been linked to fertility issues such as ovulatory dysfunction and decreased ovarian reserve. High LDL levels and low HDL levels have also been associated with an increased risk of pregnancy complications such as pre-eclampsia and gestational diabetes.

In men, high LDL levels and low HDL levels have been linked to reduced sperm quality and fertility.

Nutrition can play a role in improving these biomarkers, as a healthy diet can help to lower LDL (low-density lipoprotein) or “bad” cholesterol levels and increase HDL or “good” cholesterol levels. Therefore, a balanced and healthy diet, along with regular physical activity, can help to improve cardiovascular health and optimise fertility.

Testing for hemoglobin levels is important when trying to conceive because hemoglobin is an essential protein found in red blood cells that carries oxygen to tissues throughout the body, including the reproductive organs. Adequate levels of hemoglobin are necessary for healthy fertility and pregnancy outcomes.

Low hemoglobin levels can lead to anemia, a condition where the body does not have enough red blood cells or hemoglobin to meet its oxygen needs. In women, anemia can cause irregular menstrual cycles, ovulatory dysfunction, and decreased ovarian reserve. Anemia can also increase the risk of pregnancy complications such as preterm birth, low birth weight, and maternal mortality. In men, low hemoglobin levels have been associated with decreased sperm quality and fertility.

hs-CRP (high-sensitivity C-reactive protein) is a biomarker of inflammation. Inflammation can be caused by a variety of factors, including infections, injuries, and chronic diseases, and can affect reproductive health.

Inflammation can interfere with normal hormone function and impact fertility by disrupting ovulation and sperm production.

High levels of hs-CRP have been associated with reduced fertility in both men and women. In women, elevated levels of hs-CRP have been linked to ovulatory dysfunction, endometriosis, and implantation failure. In men, high levels of hs-CRP have been associated with decreased sperm quality and infertility.

In addition, elevated levels of hs-CRP have been linked to an increased risk of pregnancy complications such as preterm birth, preeclampsia, and gestational diabetes.

Therefore, including hs-CRP in fertility hormone testing can help identify potential inflammation that may be impacting fertility and increase the chances of successful conception and a healthy pregnancy. If hs-CRP levels are elevated, addressing the underlying causes of inflammation through lifestyle changes or medical treatment may improve fertility outcomes.

Iron is an essential nutrient that plays a critical role in many bodily functions, including reproductive health. Iron studies, which include measuring iron, ferritin, TIBC (total iron-binding capacity), UIBC (unsaturated iron-binding capacity), and transferrin saturation, can be included in fertility hormone testing when trying to conceive.

Low levels of iron can lead to anemia, a condition where the body does not have enough red blood cells or hemoglobin to meet its oxygen needs. In women, anemia can cause irregular menstrual cycles, ovulatory dysfunction, and decreased ovarian reserve, which can be identified through fertility testing. Anemia can also increase the risk of pregnancy complications such as preterm birth, low birth weight, and maternal mortality.

Iron studies can help identify iron deficiency and anemia, and provide valuable information about the body’s iron status. Ferritin, for example, is a protein that stores iron in the body, and low levels of ferritin can indicate iron deficiency even if the iron levels appear normal.

Iron studies are particularly important for women who are planning to become pregnant, as iron requirements increase during pregnancy to support fetal growth and development. Low iron levels during pregnancy can lead to poor fetal growth, preterm birth, and low birth weight.

Therefore, including iron studies in fertility hormone testing can help identify potential iron deficiency and anemia that could be affecting reproductive health, and address them through lifestyle changes or medical treatment to improve fertility and pregnancy outcomes.

LDL (low-density lipoprotein) cholesterol is a type of cholesterol that can be included in fertility hormone testing when trying to conceive. LDL is considered to be “bad” cholesterol because high levels of LDL have been linked to an increased risk of cardiovascular disease, which can have implications for fertility and pregnancy outcomes.

Studies have shown that high levels of LDL cholesterol can be associated with a decreased ability to conceive, as well as an increased risk of pregnancy complications such as gestational diabetes, preeclampsia, and preterm birth. In men, high levels of LDL cholesterol have been linked to decreased sperm quality and infertility.

Including LDL cholesterol in fertility hormone testing can help identify potential cardiovascular risk factors that could be affecting fertility and pregnancy outcomes. If LDL cholesterol levels are elevated, addressing the underlying causes through lifestyle changes or medical treatment can improve fertility outcomes and reduce the risk of pregnancy complications.

It’s important to note that cholesterol levels can be affected by factors such as diet, exercise, and genetics. Therefore, a healthcare provider may recommend regular monitoring of cholesterol levels as part of a comprehensive fertility evaluation, and offer guidance on lifestyle changes that can help optimise fertility health.

LH plays a crucial role in both male and female reproductive systems, and its levels can provide valuable information about the function of the ovaries and testes.

In women, LH is responsible for triggering ovulation, the process where the mature egg is released from the ovary and can be fertilized by sperm. LH levels typically surge just before ovulation occurs, and tracking LH levels through fertility hormone testing can help identify the most fertile period in a woman’s menstrual cycle. Measuring LH levels can also help diagnose conditions such as polycystic ovary syndrome (PCOS), a common cause of infertility in women.

In men, LH is essential for the production of testosterone, the male sex hormone that is necessary for sperm production. LH stimulates the Leydig cells in the testes to produce testosterone, which is then converted to sperm in the seminiferous tubules. Measuring LH levels in men through fertility hormone testing can help diagnose conditions such as hypogonadism, where the testes do not produce enough testosterone or sperm.

Therefore, including LH in fertility hormone testing can help identify potential underlying causes of infertility. This information can be used to guide fertility treatment options, such as timed intercourse, intrauterine insemination, or in vitro fertilisation, to improve the chances of achieving pregnancy.

Magnesium is often included in a comprehensive nutritional test when evaluating fertility, as it is an important mineral for reproductive health. In addition to hormone testing, evaluating an individual’s nutritional status can provide valuable insights into potential underlying factors contributing to infertility.  Magnesium plays an important role in many physiological processes, including muscle and nerve function, blood sugar regulation, and bone health. In the context of fertility, magnesium has been shown to be involved in many aspects of reproductive health.

Studies have suggested that magnesium may play a role in female fertility by promoting healthy ovulation and supporting the implantation of a fertilized egg. Magnesium also helps to regulate the menstrual cycle by controlling the levels of other hormones such as estrogen and progesterone. In men, magnesium is essential for the production of healthy sperm, and low levels of magnesium have been linked to decreased sperm count and motility.

Magnesium deficiency is not uncommon, and can be caused by factors such as poor diet, stress, and certain medical conditions. Low magnesium levels have been linked to decreased fertility in both men and women. Therefore, including magnesium in a nutritional test can help identify any deficiencies that may be contributing to infertility and guide recommendations for dietary changes or supplementation to help optimise magnesium levels and improve fertility outcomes.

Oestradiol is an important hormone that is included in fertility hormone testing to assess reproductive health and function in both men and women, whether they are experiencing infertility or not.

In women, oestradiol plays a key role in the development and maturation of the follicles in the ovaries, and helps to thicken the uterine lining in preparation for implantation of a fertilized egg. Monitoring oestradiol levels can provide important insights into ovarian function and can help identify any issues that may affect fertility, such as hormonal imbalances or conditions like PCOS.

In men, oestradiol is also important for reproductive health as it helps to regulate the production of testosterone. Imbalances in oestradiol levels can lead to decreased testosterone levels, which can in turn lead to decreased sperm count and motility.

When oestradiol is included in fertility hormone testing, important insights into reproductive health can be gained and hormonal imbalances that may impact fertility can be identified. This proactive approach to fertility checking can help individuals optimise their fertility health and improve their chances of conceiving when the time is right.

In women, prolactin levels can impact ovulation by suppressing the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which are both essential for ovulation. High levels of prolactin can lead to irregular menstrual cycles, and in some cases, may prevent ovulation altogether.

In men, prolactin also plays a role in reproductive health by stimulating the production of testosterone. However, when prolactin levels are too high, it can suppress the production of testosterone and lead to a decrease in sperm production. When you include prolactin in your fertility hormone testing, you can gain important insights into your reproductive health and identify any hormonal imbalances that may affect your ability to conceive. This proactive approach to fertility checking can help you optimise your reproductive health and increase your chances of conceiving when the time is right for you.

Sex Hormone-Binding Globulin (SHBG) plays a crucial role in both male and female fertility by regulating the levels of sex hormones in the body. In females, SHBG helps transport estrogen and testosterone to their target tissues and prevents their excessive accumulation in the body. This is important for the normal development and function of the female reproductive system, including regular menstrual cycles and ovulation.

In males, SHBG primarily binds to testosterone and regulates its levels in the body. This helps maintain the balance between testosterone and estrogen, which is important for the normal development and function of the male reproductive system, including sperm production and maturation.

Low levels of SHBG have been linked to reproductive issues in both males and females, such as polycystic ovary syndrome (PCOS) in females and erectile dysfunction and decreased sperm quality in males. Therefore, including SHBG in your fertility hormone testing can help identify any hormonal imbalances that may be impacting your fertility and take steps to address them.

If you are trying to conceive or planning on becoming a parent in the future, it’s important to understand the crucial role that a comprehensive sperm test plays in male fertility. 

A comprehensive semen analysis measures several factors, including sperm count, motility, and morphology. Abnormalities in any of these areas can impact male fertility.

Here’s a breakdown of the different factors that are measured during a semen analysis and why they are important:

1. Visual Appearance: The visual appearance of semen is an important factor to consider during a semen analysis. Semen should be a white or greyish colour, and should not have any signs of blood or other unusual colorations.
2. pH: The pH of semen should be slightly alkaline, typically between 7.2 and 7.8. A lower or higher pH can indicate an underlying health issue that may be affecting fertility.
3. Viscosity: Semen should have a thick, jelly-like consistency that becomes more fluid after ejaculation. If the semen is too thick or too watery, it can be a sign of underlying issues with sperm quality and quantity.
4. Volume: The volume of semen produced is also an important factor to measure. Typically, a healthy semen sample will contain between 1.5 to 5 millilitres of fluid. A lower or higher volume can indicate underlying health issues.
5. Concentration: Concentration refers to the number of sperm present in a given amount of semen. A normal sperm concentration is considered to be 15 million or more sperm per millilitre of semen. A lower concentration can indicate fertility issues.
6. Total Count: Total sperm count is the total number of sperm present in the semen sample. A healthy sperm count is generally considered to be 39 million or more in a typical sample.
7. Motility: Sperm motility refers to how well the sperm are able to move. Healthy sperm should have good forward movement, which is essential for fertilisation. A motility rate of 40% or more is considered healthy.
8. Morphology: Sperm morphology refers to the size, shape, and appearance of sperm. Healthy sperm should have a normal shape and size, with a round head and long tail. A morphologically normal sperm rate of 4% or more is considered healthy.
9. Immunology: Antisperm antibodies are immune system cells that attack and damage sperm, making it difficult or impossible for them to fertilise an egg. The presence of these antibodies can be a factor in infertility.
10.  

TSH, or thyroid-stimulating hormone, is an important hormone that plays a role in fertility for both men and women. Including TSH in fertility hormone testing is crucial for anyone trying to conceive or wanting to maintain good fertility health. TSH is produced by the pituitary gland and helps to regulate thyroid hormone production. Thyroid hormones are important for regulating metabolism and maintaining overall health. However, an imbalance in TSH levels can indicate an underlying thyroid issue, which can negatively impact fertility.

In women, high TSH levels can lead to irregular menstrual cycles, anovulation, and infertility. In men, high TSH levels can lead to decreased sperm motility and lower semen volume.

Therefore, testing TSH levels as part of a comprehensive fertility hormone panel can identify any underlying thyroid issues that may be affecting fertility. Taking a proactive approach to fertility checking can help you optimise your reproductive health and improve your chances of conceiving when the time is right.

Total cholesterol is an important biomarker for assessing nutritional health in the context of trying to conceive. High levels of total cholesterol can indicate poor dietary choices, which can have negative effects on fertility.

For women trying to conceive, high levels of cholesterol can increase the risk of conditions such as polycystic ovary syndrome (PCOS), which can make it more difficult to conceive. It can also lead to complications during pregnancy such as gestational diabetes and pre-eclampsia.

In men, high levels of cholesterol can lead to erectile dysfunction and other sexual health problems, which can impact fertility. Additionally, high cholesterol levels can contribute to oxidative stress and inflammation, which can damage sperm DNA and decrease sperm quality.

A comprehensive nutritional test that includes total cholesterol can help identify any potential dietary or lifestyle factors that may be affecting cholesterol levels and can help you make changes to improve your overall nutritional health and fertility outcomes. This proactive approach to fertility checking can ultimately increase the chances of conception and improve overall reproductive health.

Triglycerides are a type of fat that can be found in your blood. When it comes to fertility health, it’s important to keep an eye on your triglyceride levels because high levels of triglycerides have been linked to lower fertility in both men and women.

When your triglyceride levels are too high, it can affect your reproductive health by causing hormonal imbalances and even interfering with ovulation or sperm production. In addition, high triglycerides can lead to other health complications that can make it harder to conceive, such as insulin resistance, inflammation and oxidative stress. 

Oxidative stress is a process that occurs when there is an imbalance between the production of free radicals and the body’s ability to neutralise them. Free radicals are unstable molecules that can cause damage to cells and DNA, leading to various health problems, including infertility.

Inflammation, on the other hand, is the body’s natural response to injury or infection. However, chronic inflammation can also contribute to a range of health issues, including infertility. High levels of triglycerides have been linked to increased levels of inflammation in the body, which may affect reproductive health.

Therefore, it’s important to monitor your triglyceride levels as part of your overall fertility health. Lowering your triglyceride levels through lifestyle changes, such as regular exercise and a healthy diet, may help reduce oxidative stress and inflammation in the body, promoting better reproductive health.

If you’re trying to conceive, it’s important to ensure that your body has all the necessary nutrients to support a healthy pregnancy. Vitamin B12 is one of these essential nutrients, and having a deficiency in this vitamin can impact your fertility and increase the risk of complications during pregnancy.

Ensuring that you have adequate levels of vitamin B12 is crucial when trying to conceive. Vitamin B12 is an essential nutrient that your body needs to produce DNA and red blood cells, as well as to keep your nervous system functioning properly.

In men, low levels of vitamin B12 can lead to reduced sperm count and motility, while in women, a deficiency in B12 has been associated with an increased risk of ovulatory disorders and miscarriages. Taking vitamin B12 has been shown to improve the thickness of the uterine lining, which can improve your chances of successfully implanting a fertilized egg.

It’s important to note that vitamin B12 is mainly found in animal-based foods like meat, fish, and dairy products. If you’re a vegan or vegetarian, you may be at a higher risk of vitamin B12 deficiency if you don’t take supplements or consume fortified foods.

By including vitamin B12 in your nutritional testing as part of proactive fertility health, you can make sure that you have adequate levels of this important nutrient to support your reproductive health.

Vitamin D is a crucial nutrient that is essential for the body’s overall health, including reproductive health. For those trying to conceive, adequate levels of vitamin D are important for both male and female fertility.

In men, low levels of vitamin D have been linked to lower testosterone levels and reduced sperm quality. In women, vitamin D deficiency has been associated with a higher risk of ovulatory disorders and polycystic ovary syndrome (PCOS), which can make it more difficult to conceive. Additionally, vitamin D has been shown to help regulate the menstrual cycle and support the growth and development of a healthy foetus.

It’s important to note that vitamin D is mainly obtained from exposure to sunlight, but it can also be found in certain foods such as fatty fish, egg yolks, and fortified products. However, many people do not get enough vitamin D from their diet or exposure to sunlight, and may need to take supplements.

By including vitamin D in nutritional testing as part of proactive fertility health, you can ensure that you are getting adequate levels of this important nutrient to support your reproductive health. Your healthcare provider can also help you determine the appropriate dosage of vitamin D supplements, based on your individual needs and test results.
