Testosterone is an important hormone which regulates a significant number of bodily functions from sex drive, fertility and mood to muscle mass, fat distribution, and the production of red blood cells.
Sex Hormone Binding Globulin (SHGB) controls the quantity of hormones available for your body to use. Therefore, too much or too little SHBG can indicate that your body has more or less hormones available than what it needs.
Free Androgen Index (FAI) is a ratio calculated using testosterone and SHBG levels, to indicate how much free testosterone is available to be used for essential bodily functions.
Oestradiol is a steroid hormone which is involved in controlling erectile function, libido, and sperm production. As men get older, oestradiol levels naturally rise as testosterone levels fall.
Prolactin is a hormone made in your pituitary gland, which regulates testosterone secretion and sperm production.
Elevated levels of oestradiol and prolactin can lead to fertility issues.
