The Luteinizing hormone (LH), a glycoprotein hormone produced by the anterior pituitary, is essential for reproduction in both men and women. The Luteinizing (Lh) Test Kit is designed to test for Luteinizing Hormone (LH) and accurately assesses LH levels in the blood.

In women, controlled by a negative feedback loop involving several ovarian hormones, gonadotropin-releasing hormone (GnRH) is secreted in pulses from the hypothalamus, which stimulates LH production from the pituitary gland. As a result, a surge of LH production lasting around 48 hours occurs at the end of the follicular phase in a regular menstrual cycle. This sudden burst of LH causes luteinisation of the ovarian follicles and triggers ovulation.

In men, LH acts on the Leydig cells of the testes to stimulate the production of testosterone, which is necessary for sexual function and spermatogenesis. LH levels are helpful for the clinical assessment of infertility: low levels in men can result in hypogonadism and insufficient sperm production. In women, LH levels are used to determine the occurrence of ovulation for couples trying to conceive. High LH levels are seen in polycystic ovarian syndrome and in precocious puberty; levels are similar to those seen in reproductive-age individuals instead of the lower levels normally seen in children.
