FSH and LH
The FSH and LH tests are carried out in both men and women for infertility. The amount of Luteinizing hormone (LH) and Follicle-stimulating hormone (FSH) along with other hormones are measured in this test for both men and women to determine infertility. These hormones level determine whether male or female reproductive organs are accurately functioning or not.
What are FSH and LH?
LH is a hormone produced in the pituitary gland. If you are a woman, the LH levels are an important part of your menstrual cycle. It works in sync with FSH, which is also made in the pituitary gland. FSH stimulates ovarian follicles in women, which results in the growth of the egg. This hormone is also responsible for triggering the estrogen production in the follicle. If the estrogen level rises, it tells the pituitary gland to halt the production of FSH and to make more LH. The LH level shifts cause an egg to get released from the ovary, which is called ovulation. The cells proliferate in the empty follicle turning into corpus luteum. It releases progesterone hormone, which is necessary for maintaining pregnancy. And if the woman doesn't get pregnant, the progesterone level drops off, and the cycle begins again. Even in men, the pituitary gland also produces LH. The hormone links the receptors to Leydig cells in the testes. This increases the levels of testosterone, which is essential for producing sperm cells.
Why the FSH and LH Hormones Blood Testing Important?
Both the LH and FSH hormones are interlinked with each other. And they help in determining whether the sex organs are working properly or not. The tests monitor the hormone levels.
In women, the test is done when there are:
In men, the levels of LH and FSH are tested, for the following:
If the LH and FSH levels are high in women, it indicates:
In men, the high levels of LH and FSH indicate that:
