FSH LH TSH Prolactin Profile Test in Titwala

FSH LH TSH Prolactin test is a blood test to measure hormonal levels of FSH (Follicle stimulating hormone), LH (Luteinizing hormone), Prolactin and TSH in blood. All these four hormones are produced by the pituitary gland. 
FSH and LH are present both in men and women. In women it controls the menstrual cycle and stimulates the production of eggs (ovulation). In men it stimulates the production of sperm. It is present in low levels in children until puberty, post which the FSH levels increase to stimulate the production of oestrogen and testosterone.
Prolactin acts primarily on the mammary glands and its principal action involve - proliferation of mammary glands ; initiation of milk secretion . The levels of this hormone rises in pregnancy and during lactation. 
TSH is synthesized by the pituitary gland and promotes the stimulation of T3 and T4 hormones and controls the metabolic rate in body

Overview

The FSH-LH-Prolactin-TSH test is used to measure the amounts of certain hormones in the blood. FSH stands for Follicle Stimulating Hormone, LH for Luteinising Hormone and TSH for Thyroid Stimulating Hormone. FSH in women is especially active during the first two weeks of the period cycle as it makes the ovaries produce increased amounts of estrogen and some progesterone. FSH maintains normal production of sperm in men. LH has similar roles in the fertility function in both men and women. TSH helps in the production of thyroid hormone which maintains normal metabolic functions of the body.

All of these hormones are secreted by the pituitary gland in the brain. The hormones FSH and LH are present in both men and women. In women, it helps in maintaining the menstrual cycle and plays a role in ovulation. In men, FSH helps in maintaining normal sperm production. These hormones are present in very small amounts in children till they hit puberty.

Prolactin is present in women and it stimulates milk production from the mammary glands. Prolactin increases especially during pregnancy and lactation.

TSH stimulates the thyroid gland to produce hormones T3 and T4 and it plays a role in controlling the metabolism of the body.
