Question

Ovulation occurs under the influence of
(a) LH (Luteinizing hormone)
(b) FSH (Follicle- stimulating hormone)
(c) Estrogen
(d) Progesterone

Answer 1

Hint: This hormone stimulates the development of the corpus luteum and the secretion of progesterone. It is a type of gonadotropin hormone, which is secreted by hypothalamus glands.

Complete answer:
Ovulation occurs under the influence of Luteinising hormones (LH) , which are called gonadotropic hormones. They're produced and released by the group of cells of the anterior pituitary gland. It is one among the most hormones that control the reproductive system by controlling the function of female reproductive organs – ovaries and male reproductive organs – testes.
The functions of LH are:
- They are liable for ovulation in females. - They have a crucial role within the cycle. - They are liable for the production of sperm in males. - They stimulate estrogen and progesterone production from the ovary. - They stimulate the corpus luteum to progesterone production. - They stimulate testosterone production from the interstitial cells of the testes.
So, the correct answer is ‘LH (Luteinizing hormone) ’.

Additional information:
Follicle-stimulating hormone (FSH), which promotes the maturation of ovarian follicles and the secretion of estrogen, resulting in ovulation. FSH is therefore predominantly active within half of the cycle. Its secretion is suppressed once ovulation has taken place, to stop other follicles maturing during the present cycle.
Estrogen is the primary female sex hormone. It is liable for the development and stimulation of the female reproductive system and secondary sex characteristics.
Progesterone is a sex hormone that occurs in the menstrual cycle, pregnancy, and embryogenesis. They prepare the endometrium for the potential of pregnancy after ovulation. It triggers the lining to thicken to accept a fertilized egg.
Note: In males, the increased levels of LH lead to primary and secondary testicular failure. Males with increased levels of FSH leads to a genetic disease, which affects sexual development, which frequently causes infertility. In some cases, Klinefelter's syndrome is seen in males with increased levels of FSH.
