The hormone than prepares the ovary to release another ovum is a. luteinizing hormone. b. follicle-stimulating hormone. c. estrogen. d. testosterone. Ovulation: Ovulation is a hormonally-controlled event that involves the rupture of ...
a) Luteinizing hormone is produced by the corpus luteum b) Progesterone is produced by the corpus luteum c) Follicle-stimulating hormone is produced by the hypothalamus d) During the female reproductive cycle, ovulation primarily occurs due to a surg...
Noun1.luteinizing hormone- a gonadotropic hormone that is secreted by the anterior pituitary; stimulates ovulation in female mammals and stimulates androgen release in male mammals ICSH,interstitial cell-stimulating hormone,LH gonadotrophic hormone,gonadotrophin,gonadotropic hormone,gonadotropin- hormone secrete...
In some anurans, a period of low temperature (hibernation) can be essential for ovulation [35, 36] as the function of the toad ovary switches from vitellogenic growth to follicular maturation [37]. Possibly, the females' lack of response to a single ovulatory dose of hormone is from the ...
concluded that SMD is able to block the LH surge and ovulation in rats [33]. Ketaconazole inhibits various enzymes which belong to the CYP450-dependent monooxygenases and also inhibits progesterone synthesis [28, 36]. 2. Interference with hormone storage and release Interference with hormone stora...

The action of follicle-stimulating hormone (FSH) on the follicle is necessary before LH can exert its influence on the ovary. Ovulation, which is induced by LH, depends on the stage of follicular development, for which both the action time of LH and an optimal ratio of LH to FSH are ...
[10]. A follicle is the morphological unit of the ovary that produces oocytes surrounded by follicle cells (theca and granulosa) [58]. The gonadotropin hormones stimulate the secretion of progesterone and testosterone in the ovarian follicles [59]. Luteinizing hormone (LH) stimulates the release ...

Age-related defects include altered transport of cholesterol, a hormone precursor, into the mitochondria and LH-stimulated cAMP production for intracellular signaling [121,124,129,132,134,162]. In light of this evidence, it stands to reason that ageing can reduce testosterone function by mechanisms...
