FSH(Follicular Stimulating Hormone), LH(Leuitinizing Hormone): It is a key component in male fertility because it stimulates the growth of sperm. When a man has a high level of FSH, it means that the testicles are not producing enough of a hormone called inhibin, which keeps FSH levels in their normal range. LH binds with the Leydig cells in the testes to promote the release of testosterone, which is necessary to the production of sperm cells. Both LH and FSH are vital to the proper production of sperm. Low levels of these hormones can be at least partly responsible for low sperm counts, which is the biggest cause of infertility in men.
Testosterone: It is a primary male sex hormone which plays a key role in the development of male reproductive tissues such as testes and prostate. as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair.
Thyroid Profile: The TSH test measures the level of Thyroid-Stimulating Hormone in your blood. The TSH has a normal test range between 0.4 and 4.0 milli-international units of hormone per liter of blood (mIU/L). The effect is felt in the entire endocrine system leading to male hormonal imbalance, and infertility.
Prolactin: Elevated levels of prolactin in the blood signals the gonads to make less testosterone (hypogonadism). This means that hyperprolactemia can indirectly but definitely cause decreased libido, erectile dysfunction, dimished ejaculate volume, and a low concentration of sperm (oligospermia), and enlarged breasts (in men this is called gynaecomastia).
