The demonstration that luteinizing hormone (LH) release from the pituitary is episodic rather than constant raises fundamental questions regarding the physiologic control of pulsatile LH secretion and its possible alteration in patients with gonadal disorders. To evaluate this mode of LH secretion, ...

Luteinizing hormone, also known as corpus luteinizing hormone, is a glycoprotein produced by the adenohypophysis. The effect on women contains ovulation and luteal formation, regulating the menstrual cycle and promoting the synthesis of estrogen and androgens. The effect on men is promoting the maturat...
(ovulation) from the ovary, in the female, and testosterone from the testicle, in the male. In men, rising blood levels of testosterone inhibit secretion of luteinizing hormone, while, in women, rising levels of oestradiol (estradiol) prompt an increased secretion of luteinizing hormone in the ...

A luteinizing hormone test measures how much luteinizing hormone (LH) is in your blood. LH helps your reproductive system: specifically, a woman’s ovaries and a man’s testes. It’s also called lutropin and interstitial cell stimulating hormone. It’s made in your pituitary gland, which is...
Compared to saline-treated controls, hCG had no significant effect in either men or postmenopausal women on the basal LH concentration or the response to a GnRH bolus, as determined by peak response and area under the LH/time curve between 0-300 min after GnRH. We conclude that an ultra...
Luteinizing hormone Urine luteinizing hormone (LH) concentration is routinely measured in all antidoping laboratories to exclude recombinantLHabuse and to test any potential alteration of the hypophyseal–gonadal axis. In adult men, LH released from the anterior pituitary stimulates the secretion...
