FSH, LH, Prolactin & TSH near me in Madurai

The Follicle Stimulating Hormone test measures the level of FSH in your body. FSH is produced and subsequently released into the blood by the pituitary gland. Its production is controlled by a feedback mechanism involving a hormone situated in the hypothalamus in the brain. The released FSH travels through your blood and then attaches to receptors in the ovaries and testes. It exerts functional effects on the reproductive organs, such as sexual development, puberty, and maturation. FSH levels vary throughout the menstrual cycle in response to estradiol and progesterone. Any disruption or issue in this feedback mechanism can prevent the normal function of the testicles or ovaries. Thus, determining its level provides crucial information regarding your health.

The TSH (Thyroid Stimulating Hormone) Ultrasensitive test measures the levels of TSH hormone in the blood. TSH is produced by the pituitary gland located in the brain. Its function is to stimulate and regulate the functioning of the thyroid gland. It signals the thyroid gland to increase or decrease the production of thyroid hormones T3 and T4 (essential for regulating our body’s metabolism, temperature, heart rate, and growth) when their levels are low or high, respectively. Therefore, when the levels of T3 & T4 decrease, the pituitary gland is stimulated to release TSH. This high TSH level, in turn, stimulates the thyroid gland to release more thyroid hormones (T3 & T4); the vice-versa happens when the levels of thyroid hormones increase.

The Serum Prolactin test measures the levels of prolactin hormone in a person’s body. During pregnancy, prolactin, estrogen, and progesterone hormones stimulate breast milk development. Following childbirth, prolactin helps initiate and maintain the breast milk supply. If a woman does not breastfeed, her prolactin concentration will soon drop back to pre-pregnancy levels.

Besides pregnancy, the most common cause of elevated prolactin concentration is prolactinoma, a prolactin-producing tumor of the pituitary gland. Prolactinomas are the most common type of pituitary tumor and are usually benign (non-cancerous). They develop more frequently in women but are also found in men.

If the pituitary gland and/or the tumor enlarge significantly, it can put pressure on the optic nerve, causing headaches and visual disturbances, and can interfere with the other hormones that the pituitary gland produces.

The Luteinising Hormone test determines the level of luteinizing hormone that promotes the functioning of the gonads, i.e., testes in men and ovaries in women. LH is produced by the pituitary gland, a pea-sized gland situated at the base of the brain. The production and release of LH are controlled by a system known as the hypothalamic-pituitary-gonadal axis. A hormone called GnRH is released from the hypothalamus of the brain and binds to the cell receptors in the anterior pituitary gland, which in turn prompts the synthesis and release of luteinizing hormone. LH then travels across the blood and attaches to its target cells in the testes in men and ovaries in women to facilitate optimal sexual and reproductive activities.
