This pituitary hormone works in concert with FSH. FSH starts the development of the egg, and LH finishes the development and starts progesterone production. FSH is important to stimulate the cells of the follicle to produce Estrogen. LH is important to stimulate the cells of the follicle that produce Progesterone during the second half of the menstrual cycle. A certain ratio of FSH to LH tells the ovary when to release the egg (ovulation). In the male, LH stimulates the testicles to produce the male hormone testosterone.

During ovulation in women, the level of LH surges causing the egg to be released from the ovary. In men, LH stimulates production of testerone which also contributes to the development of mature sperm.
Pituitary hormone that causes the testicles in men to manufacture testosterone; in women LH stimulates production of hormones in the ovarian follicle and also triggers ovulation.
In women, the pituitary hormone that triggers ovulation and stimulates the corpus luteum of the ovary to secrete progesterone and androgens during the second half of the menstrual cycle.

Read more about how the Fertility Monitor tracks LH levels and determines your level of fertility in our section on the Fertility Monitor.
A pituitary hormone that stimulates the ovary. Whenestrogen reaches a critical peak, the pituitary releases a surge of LH (theLH spike) that releases an egg from the follicle.

A hormone produced by the pituitary gland located at the base of the brain. In men, LH stimulates the production of testosterone, a hormone necessary for sperm production. In women, LH causes ovulation.
A glycoprotein gonadotropic hormone of the anterior pituitary, which acts with the follicle-stimulating hormone to cause ovulation and secretion of estrogen. In the male, it stimulates the development and functional activity of some testicular cells.
Pituitary hormone that stimulates estrogen secretion, ovulation, and formation of the corpus luteum.
A hormone secreted by the pituitary gland. Secretion of LH increases in the middle of the cycle to induce release of the egg.
(LH) The hormone, or gonadotropin, produced by the pituitary gland to cause, in women, ovulation of a mature follicle in the ovary, resulting in formation of the corpus luteum; in men, stimulates the production of testosterone by the Leydig cells of the testis. Suppressed by GnRH-agonists and GnRH-antagonists, so that (for ovulation induction) an injection of human chorionic gonadotropin (hCG), which acts the same way, has a predictable time course of action. A small amount of LH is essential for normal function of the tertiary follicle and the corpus luteum. See also LH surge and serum LH. Recombinant LH is under development by Serono as Luveris, but its clinical role in place of hCG is not yet established.

LH) The female hormone that triggers ovulation. Abnormal levels may indicate lack of ovarian reserve. Doctors also often look at the LH:FSH ratio to determine if there are any ovulation problems or other conditions that may affect fertility.
Produced by the pituitary gland; in combination with FSH, it stimulates the ovary to release the egg (ovulation).
Around the middle of your menstrual cycle, estrogen triggers a surge of LH, which causes the strongest egg to burst through the ovary wall and move towards the uterus. LH is the substance detected by ovulation predictors. High levels of this hormone can be an indicator of Polycystic Ovary Syndrome.
