Which hormone stimulates testosterone release? What is the hormone secreted by the anterior pituitary that triggers ovulation and then promotes formation of the corpus luteum? What hormones are produced by the
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 surge...
The neuroendocrine control of ovulation and broodiness in the domestic hen involves complex interactions between hypothalamic neuropeptides, neurotransmitters, and ovarian steroids which regulate the secretion of luteinizing hormone (LH) and prolactin. Nuclear progesterone receptor is localized in many neurons...
In vertebrates, folliculogenesis and ovulation are regulated by two distinct pituitary gonadotropins: follicle-stimulating hormone (FSH) and luteinizing hormone (LH). Currently, there is an intriguing consensus that a single hypothalamic neurohormone, gonadotropin-releasing hormone (GnRH), regulates the se...

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...
To determine which hormone induces ovulation, let's analyze the options provided:1. FSH (Follicle Stimulating Hormone): - FSH is primarily responsible for the growth and maturation of ovarian follicles. It stimulates the ov
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 ...
[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 ...
Fill in the blanks: ___ (hormone) produced by G cells in the pyloric antrum stimulates ___ secretion in the stomach. The function of parafollicular cells in the thyroid gland is to produce which of the following? a. Calcitonin b. Insu...
