Luteinizing hormone (LH ) is a gonadotropin (a hormone that affects the function of the sex organs) released by the pituitary gland. In women, LH controls the length and sequence of the menstrual cycle, including ovulation, preparation of the uterus for implantation of a fertilized egg, and ovarian production of both estrogen and progesterone. In men, LH stimulates the testes to produce androgen. Also known as interstitial-cell-stimulating hormone (ICSH).
Your blood spot samples will test: LH (Luteinizing Hormone)levels.

The LH Blood Spot home test measures the amount of Luteinizing Hormone (LH) in your bloodstream. LH is produced in the pituitary gland, located at the base of the brain. This hormone is known as a gonadotropin, and it affects the sex organs in both men and women.
In women, the amount of LH in the bloodstream varies throughout the menstrual cycle and changes with pregnancy. LH plays a role in puberty, menstruation, and fertility. It partners with the follicle-stimulating hormone (FSH), another gonadotropin also made in the pituitary gland. When there is a rise in estrogen, your pituitary gland is signaled to stop producing FSH and to start making more LH. Increased LH makes the egg release from the ovary, which is known as ovulation. In the empty follicle, cells proliferate, turning it into a corpus luteum which releases progesterone, a hormone necessary to maintain pregnancy. If pregnancy doesn�t occur, the levels of progesterone drop off and the cycle begins again.
LH is a marker that helps determine the causes of infertility, as well as the beginning of menopause in women and andropause in men.
Knowing the amount of LH in your blood can indicate underlying problems associated with a variety of reproductive health issues.
