In men, FSH is a part of the development of the gonads as well as sperm production. The FSH test measures the level of FSH found in your blood.
It is used primarily to evaluate the function of the hypothalamic-pituitary-gonadal axis and aid in the diagnosis and treatment of infertility in women.
In women, LH helps control the menstrual cycle. It also triggers the release of an egg from the ovary. This is known as ovulation. LH levels quickly rise just before ovulation. In men, LH causes the testicles to make testosterone, which is important for producing sperm. Normally, LH levels in men do not change very much.
A testosterone test measures the blood level of the male sex hormone testosterone. Testosterone, which plays an important role in sexual development, is produced mainly by the testes in boys and in much smaller amounts by the ovaries in girls. Testosterone is also produced by the adrenal glands in both girls and boys.
Men — When a high blood prolactin concentration interferes with the function of the testicles, the production of testosterone (the main male sex hormone), and sperm production. Low testosterone causes decreased energy, sex drive, muscle mass and strength, and blood count (anaemia).
SEX HORMONE-BINDING GLOBULIN
The sex hormone-binding globulin (SHBG) test may be used to help evaluate men for low testosterone and women for excess testosterone production.
