What is the function of the LTH hormone?

Answer 1

At puberty, the hypothalamus produces GnRH (gonadotropin releasing hormone.) GnRH then stimulates production of LH (leutinizing hormone) and FSH (follicle stimulating hormone)which are released by the pituitary gland. In males, LH causes secretion of testosterone and other androgens by the interstitial cells (located in between the seminiferous tubules in the testies.) Testosterone,among others duties, aids FSH in the stimulation of spermatogenesis (production of spermatozoa) and promotes the functional maturation of spermatozoa.

Answer 2

Luteinizing hormone (LH, also known as lutropin) is a hormone produced by the anterior pituitary gland. In females, an acute rise of LH called the LH surge triggers ovulation and development of the corpus luteum. In males, where LH had also been calledInterstitial Cell Stimulating Hormone (ICSH), it stimulates Leydig cell production of testosterone

In both males and females, LH is essential for reproduction.

• In females, at the time of menstruation, FSH initiates follicular growth, specifically affecting granulosa cells.With the rise in estrogens, LH receptors are also expressed on the maturing follicle that produces an increasing amount of estradiol. Eventually at the time of the maturation of the follicle, the estrogen rise leads via the hypothalamic interface to the "positive feed-back" effect, a release of LH over a 24-48 hour period. This 'LH surge' triggers ovulation thereby not only releasing the egg, but also initiating the conversion of the residual follicle into a corpus luteum that, in turn, produces progesterone to prepare the endometrium for a possible implantation. LH is necessary to maintain luteal function for the first two weeks. In case of a pregnancy luteal function will be further maintained by the action of hCG (a hormone very similar to LH) from the newly established pregnancy. LH supports thecal cells in the ovary that provide androgens and hormonal precursors for estradiol production.

• In the male, LH acts upon the Leydig cells of the testis and is responsible for the production of testosterone, an androgen that exerts both endocrine activity and intratesticular activity on spermatogenesis.

The release of LH at the pituitary gland is controlled by pulses of gonadotropin-releasing hormone (GnRH) from the hypothalamus. Those pulses, in turn, are subject to the estrogen feedback from the gonads.

Answer 3

Lutenizing hormone is a hormone released by the pituitary gland, a small gland at the base of the brain. The hormone stimulates the ovaries to produce and release eggs each month during the menstrual cycle.

Answer 4

To stimulate the release of the mature egg from the ovaries.

LH ______ Primarily stimulates testosterone production by the testes

Answer 5

To stimulate the release of the mature egg from the ovaries.

Answer 6

LH is a hormone produced by the pituitary gland to stimulate the release of a mature egg in the middle of the menstrual cycle.

Answer 7
