DHEA-S (dehydroepiandrosterone sulphate) is a male hormone that is produced in the adrenal glands and is readily converted into testosterone in the body. Testosterone is responsible for a variety of traits which can range from; increasing the mass of bone and muscle to influencing the growth of hair on the body. In women, DHEA-S may be raised in individuals with polycystic ovary syndrome. High levels of DHEA-S may also be a contributing factor to excessive bodily hair growth (hirsutism) in women due to increased amounts of DHEA-S being converted to testosterone. In both men and women, elevated DHEA-S may be caused by Cushing's Disease or an overactive adrenal gland that may be caused by an adrenal tumour. Whilst low levels of DHEA-S may also be caused by impaired functioning of the adrenal glands that can result in symptoms including loss of libido or issues with fertility.


Follicle-stimulating hormone (FSH) is produced by pituitary gland and plays a key role in the reproductive system of both men and women. In women, FSH regulates the growth of ovarian follicles which secrete progesterone and Estrogen that are required for key events during the menstrual cycle. In men, FSH plays a key role in the development of the testes as well as the production of sperm.


"Luteinizing hormone (LH) is produced in the anterior pituitary gland and plays an important role in regulating the function of the reproductive tissues which include the ovaries in females and testes in males.

In women, during the first half of a typical menstrual cycle (roughly weeks one to two), LH is required to stimulate the ovarian follicles that are located in the ovaries to produce the female sex hormone oestradiol. LH naturally rises at around day 14 of a women’s cycle and this surge is vital in stimulating the ovaries to release an egg during ovulation. Given fertilization occurs, LH also stimulates the corpus luteum, which secretes progesterone that is essential for sustaining pregnancy.

For men, LH plays a key role in stimulating the production of the main male sex hormone (testosterone) from Leydig cells present in the testes. Further to this, testosterone is then able to stimulate the production of sperm as well as contribute to the development of a set of characteristic traits which range from increased muscle and bone mass to the degree of bodily hair present.

LH also stimulates the production of testosterone in females. Consistently raised LH in women is often associated with polycystic ovary syndrome in which excessive amounts of testosterone are produced as a result of elevated LH. In contrast, low levels of LH may result in the halt of ovulation.

Low levels of LH may be a cause of infertility in both men and women due to levels being insufficient in stimulating sperm production or the ovulation process. "
Testosterone is a male sex hormone that is produced in the testicles of men and to a lesser extent in the ovaries of women. In men, testosterone plays an important role in the development of the male reproductive tissues including the prostate and testes. Testosterone is responsible for a variety of traits which can range from; increasing the mass of bone and muscle to influencing the growth of hair on the body. Therefore, men with lower levels of testosterone may encounter a reduction in these traits, whilst women with raised testosterone may encounter an increase in these traits. Raised testosterone is commonly observed in women with polycystic ovaries syndrome in which increased body hair, acne or a deepened voice may be characteristic.

SHBG is a protein that is produced by your liver and is able to bind tightly with three main sex hormones (dihydrotestosterone (DHT), testosterone and Estrogen). These hormones can be found in your blood in an unbound, free form in both women and men. However, when SHBG binds to them they become bound and unavailable to the cells of your body, therefore, SHBG can influence the amount of these free hormones that is available to your tissues. A high value for SHBG can indicate a lack of testosterone or oestrogen available to your tissues whilst a low SHBG value can indicate an excess amount of these hormones available. Causes for changes in the level of SHBG other than sex and age include hyperthyroidism and liver disease.


The Free Androgen Index (FAI) is a ratio used to determine the amount of free androgen hormones within the blood and whether this is within the normal range. Testosterone readily binds to proteins within the blood such as SHBG, though it can also be found in a free, unbound state. The FAI ratio is based on measurements of testosterone present in your blood in comparison to the total amount of testosterone plus SHBG in your body. In women, an elevated value for FAI could indicate polycystic ovary syndrome. In men, a low value could be indicative of a reduced availability of testosterone which may be associated to symptoms including loss of muscle mass, libido and erectile dysfunction.
Oestradiol is an important steroid hormone that can be found in both men and women. In women, oestradiol is mainly produced by the ovaries and plays a key role in the maturation and maintenance of the female reproductive system.

In comparison, men produce considerably lower amounts of oestradiol. This is mainly produced by the testes where some testosterone is converted into oestradiol which is a vital component for the production of sperm. Oestradiol may also be produced to lesser extent by fat tissue in both men and women. Elevated levels of oestradiol may lead to a host of conditions ranging from depression to acne. A raised result has also been found to be associated with an increased risk of breast and uterine cancer. In contrast, low levels may affect the menstrual cycle, fertility, mental health or even lead to osteoporosis. In men, increased oestradiol can lead to infertility, loss of libido or the development of breast tissue. Levels may rise due to the accumulation of excessive fat tissue that secretes oestradiol.
Prolactin is a hormone which is produced in the pituitary gland in both men and women. Prolactin can also influence the levels of other important hormones such as Estrogen and testosterone in both sexes. In women, prolactin stimulates the production of milk following the birth of a child. Consequently, levels are characteristically high in pregnant and breastfeeding women. However, elevated prolactin levels in both men and women that are not pregnant or breastfeeding is a condition known as hyperprolactinemia and may lead to loss of libido, bone density loss and potential infertility. In women in particular, elevated prolactin may also lead to other issues such as vaginal dryness or disruptions to the normal menstrual cycle subsequently leading to irregular periods. In comparison, symptoms specific to men in response to high levels of prolactin may include breast enlargement or erectile dysfunction.


Albumin is primarily produced by the liver and is an important protein in preventing blood from leaking out of blood vessels. Other functions of albumin range from transporting substances such as medications through the blood to playing a role in the growth and repair of tissues. Elevated levels of albumin are typically caused by dehydration. In contrast, low levels may be indicative of liver disease, inflammation or malnutrition. Levels may also be raised in conditions such as diabetes.

About this test

Our male hormone tracker PLUS provides a comprehensive, thorough, extensive and complete assessment of the key hormones in your body. This package is therefore a great tool to check whether your hormones are within a normal, healthy range. We test for an extensive panel of markers including; follicle-stimulating hormone (FSH), sex hormone-binding globulin (SHBG), luteinising hormone (LH), oestradiol, prolactin and DHEA-s. Further to this, we complete a thorough evaluation of the levels of testosterone in the body, providing three different measures including; the amounts of free testosterone, total testosterone, and the free androgen index (FAI). We also include a test for the protein albumin which helps us calculate FAI. In men, the amounts you have of all of these analytes can have an impact on several traits such as your sex drive, levels of energy, sperm production and muscle mass. Abnormal levels of these hormones could therefore lead to symptoms including; loss of libido, erectile function or infertility.

Our test is perfect for those who:

  • May be experiencing symptoms associated with a hormonal imbalance such as lack of sexual desire.
  • Are interested in assessing their fertility.
  • Desire a thorough examination of their levels of reproductive hormones to ensure they are within normal ranges.

Caution: Receiving hormones during hormone replacement therapy (HRT) will affect your results therefore, it is important to disclose this information to us so we can interpret your results much better.
