	Luteinizing hormone (LH) Test Strips
		LH increases dramatically just before women's most fertile day of the month in a process commonly referred to as the "LH Surge” This LH increase triggers ovulation, which means an egg is released from woman's ovary.
		The LH test may also be used to determine when eggs are mature enough to be surgically removed from the ovary as part of the in vitro fertilization process.
		Depending on the concentration of LH in the test specimen, positive results may be observed in as short as 40 seconds.

	Medical Conditions - Reproductive Endocrinology
		A low serum LH to FSH ratio (0.15 to 1.5) on day 2 or 3 of the menstrual cycle (depending on the length of the follicular phase) may be used as an early biomarker of poor ovarian response when evaluating potential IVF outcome.
		LH is useful for distinguishing between hypogonadism due to primary gonadal failure (increased LH and FSH) and hypogonadism caused by deficient gonadal stimulation from the pituitary gland (decreased LH and FSH).
		The interrelationship between LH and estrogen/androgen levels are illustrated by the basal LH decrease in postmenopausal women on estrogen or testosterone therapy, and the absence of the typical mid-cycle LH surge in women on oral contraceptives.

	LH Detect : Cattle (Site not responding. Last check: 2007-11-07)
		The period that elapses between the LH peak and ovulation in the cow is constant and is estimated at 24h ± 2h.
		Accurate detection of the preovulatory LH peak in females therefore enables a reliable estimation to be made of the optimal moment for artificial insemination (AI) in anestrus females having previously undergone ovulation induction treatment, particularly useful in problem herds.
		Example of plasma LH surge and estradiol-17b concentration in a superovulated cow during a CIDR-B synchronized cycle (Lafri et al., 2002).

	LH: The Test
		LH is often used in conjunction with other tests (FSH, testosterone, estradiol and progesterone) in the workup of infertility in both men and women.
		LH levels are also useful in the investigation of menstrual irregularities and to aid in the diagnosis of pituitary disorders.
		LH and FSH may be ordered when a boy or girl does not appear to be entering puberty at an appropriate age (either too late or too soon).

	LH: The Test Sample
		Control of LH production is a complex system involving hormones produced by the gonads (ovaries or testes), the pituitary, and the hypothalamus, such as gonadotrophin-releasing hormone.
		LH levels are relatively constant in men after puberty.
		In infants and children, LH levels rise shortly after birth and then fall to very low levels (by 6 months in boys and 1-2 years in girls).

	LH Surge Secretion (Site not responding. Last check: 2007-11-07)
		Surge secretion of LH results after an apparent stimulation of a LH "surge generator" in the brain by elevated estrogen secretion from preovulatory follicles and is mimicked by a single injection of estradiol in ovariectomized (OVX) gilts.
		However, the preovulatory LH surge may be only a manifestation of simply an attenuation of the negative feedback inhibition of estradiol on the pulse generator rather than subsequent positive feedback stimulation of a specific surge generator.
		Since the characteristics of the LH surge were similar among all gilts, we conclude that there is a distinct surge generator within the CNS of the pig which must be stimulated by estradiol in order for the LH surge to occur.

	ACTH, TSH, FSH, LH (Site not responding. Last check: 2007-11-07)
		LH has the same receptor as growth hormone (GH) though the source of the hormones is different.
		A second function of LH in women is that it acts upon the ruptured follicle to stimulate its conversion to a corpus luteum, which provides an ovarian source of estrogen and subsequently progesterone.
		LH is required for normal survival and function of the corpus luteum during the menstrual cycle.

		When this occurs, the LH level in the serum sample is greater than 1 nanogram per milliliter.
		Precise identification of the fertile period is made by measurement of the LH surge which actually triggers ovulation.
		While progesterone is elevated during the fertile period, the rate of rise varies from bitch to bitch, as does the absolute value of progesterone which coincides with the LH surge or with the optimal time to breed.

	LH Ross & Co., Inc. Order Revoking a Broker-Dealer and Sales Rep. License
		On December 15, 2004, a Hearing Panel of the National Association of Securities Dealers (“NASD”) issued a decision against LH Ross and Michelin for violations of NASD Conduct Rule 2110, which requires members to observe high standards of commercial honor and just and equitable principles of trade in the conduct of their business.
		As a result of its findings, the Hearing Panel in the January 14 decision expelled LH Ross from NASD membership, ordered the firm to permanently cease and desist from violating securities laws and regulations, imposed a $500,000 fine, and ordered the firm to pay over $11 million in restitution.
		Although the Notice was properly served under 32 M.R.S.A. and although LH Ross received it on February 9, 2005, respondents have neither requested a hearing nor otherwise responded to the Notice.

	Luteinizing and Follicle Stimulating Hormones
		As describef for thyroid-simulating hormone, LH and FSH are large glycoproteins composed of alpha and beta subunits.
		In females, ovulation of mature follicles on the ovary is induced by a large burst of LH secretion known as the preovulatory LH surge.
		Progesterone is necessary for maintenance of pregnancy, and, in most mammals, LH is required for continued development and function of corpora lutea.

	LH urine test (home test ) (Site not responding. Last check: 2007-11-07)
		The anterior pituitary gland secrets hormones called gonadotropins (LH is one of these), which stimulate the ovary to prepare a follicle to release an egg.
		Once the follicle has matured, a dramatic rise in LH levels (known as the "LH surge") signals the ovary to release the egg.
		While it would seem that knowing the exact time of ovulation would increase a woman's chances of getting pregnant, research finds that home urinary LH tests are no more likely to help a woman get pregnant than charting her basal body temperature during initial attempts to induce ovulation with clomiphene citrate.

	LH response to GnRH - UMMC
		GnRH stimulates the synthesis and release of LH (luteinizing hormone) and FSH (follicle-stimulating hormone).
		In women, estrogen levels increase during the menstrual cycle until a level is reached at which a positive feedback signal stimulates GnRH and LH release -- a phenomena that is responsible for the LH surge prior to ovulation.
		In men, testosterone decreases the frequency of LH pulses, probably by a direct effect on GnRH release.
