Luteinising Hormone

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 gonadotropin-releasing hormone is released from the hypothalamus of the brain and binds on 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.

Follicle Stimulating Hormone

A 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 gonadotropin-releasing 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 and exerts its 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 normal function of the testicles or ovaries. Thus determining its level provides crucial information regarding your health.

Testosterone Total

A Testosterone Total test measures the level of testosterone hormone in the blood. Testosterone is a steroid hormone primarily produced in the testes in men, although it is also present in smaller quantities in the adrenal glands. In women, it is made in small amounts by the ovaries. It is predominantly associated with male physiology and significantly influences physiological functions in both men and women. 

The pituitary gland produces luteinizing hormone (LH), which regulates testosterone production. As testosterone levels rise, LH production decreases, slowing down testosterone production. Conversely, when testosterone levels fall, LH production increases, stimulating testosterone production.

Most of the testosterone circulating in the blood gets attached to two proteins, albumin and sex hormone-binding globulin (SHBG), and some of it remains unattached, called free testosterone. Free testosterone and albumin-bound testosterone are also known as bioavailable testosterone, as they are readily available for the body to use for proper functioning.
