FSH-LH-Testosterone near me in Kattupakkam

An FSH-LH-Testosterone test measures the levels of three key hormones - follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone in the blood. These hormones are vital for hormonal function and overall reproductive health in both men and women. 

In females, FSH stimulates the growth and recruitment of immature ovarian follicles in the ovary. When the follicle matures and reaches 8–10 mm in diameter it starts to secrete significant amounts of estradiol. The sharp increase in estradiol production by the dominant follicle causes an LH surge. LH levels rise just before ovulation to trigger the release of a mature egg. This way, FSH levels help assess ovarian function in women. In males, FSH levels help assess testicular function. It helps in the growth of sperm-producing structures, while LH stimulates testosterone production.

Testosterone plays a key role in the development of male reproductive tissues such as testicles and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair.

The levels of these hormones are typically low during younger ages. However, as adolescence approaches, the brain starts producing gonadotropin-releasing hormone (GnRH). GnRH stimulates the pituitary gland to release FSH and LH. These gonadotropin hormones play a crucial role in the production of sex hormones such as testosterone, which are responsible for initiating the changes of puberty and controlling reproductive function in both men and women.
