  • Information


Follicle-Stimulating Hormone (FSH) is produced by the pituitary gland and is responsible for the growth as well as the development of male and female organs during puberty. FSH is primarily linked to egg development in females and sperm production in males. An increased FSH level in conjunction with Luteinizing Hormone can lead to infertility, low sex drive, and ovarian or testicular failure.


Testosterone is a steroid hormone found in males and females however, its role is amplified in males. It is responsible for the regulation of libido, bone and muscle mass, mood changes and fertility determination. The testosterone levels are prevalent in men during puberty when it peaks and often decreases over age. An increase in testosterone levels is associated with Polycystic Ovary Syndrome (PCOS) and testicular issues in males.


Sex Hormone Binding Globulin (SHBG) is a protein present in the bloodstream. SHBG is produced by the liver. The role of SHBG is to bind testosterone and oestradiol for circulating in the tissues of the body. The concentration of SHBG is directly relative to the level of hormones in males or females. SHBG is checked to detect low levels of testosterone in males and high levels in females.


Luteinizing Hormone (LH) is secreted by the pituitary gland and plays an essential role in regulating ovulation in females and testosterone in males. The menstrual cycle in females is also controlled by LH. A high level of LH along with FSH in the bloodstream indicates a decreased sex steroid production which can be a cause of infertility in both males and females.

Free Androgen Index

Predominantly, testosterone has a significant function in men. Testosterone is bound to albumin and SHBG. Free Androgen Index (FAI) helps you detect any changes in the androgen levels of your body. FAI is calculated for those who suffer from PCOS or Hirsutism for checking any rise in non-protein bound testosterone.

Expert’s Opinion

Experts Opinion on PCOS Tests

"In this basic test, the levels of hormones can be checked and, more importantly, the ratio of various hormones. A ratio of 2:1 or higher in the LH/FSH ratio may indicate PCOS.

With the result of the testosterone and sex hormone binding globulin levels, the free androgen index (FAI) can be calculated. In women, this is typically low. Therefore, normal or higher than normal levels may signify PCOS."
