Question

Ovulation is stimulated by
A. LH
B. FSH
C. Estrogen
D. Both A and B

Answer 1

Hint: It is the process in which an egg is released from the ovary of the female into the fallopian tube. It mostly occurs in 13–15 days before the onset of each period. The cycle of ovulation depends upon the female to female. The menstrual cycle starts from the first day of the period and continues till the next day of the periods.

Complete answer: Ovulation is the release of a mature egg from one of the ovaries, which occurs every month. A woman is most fertile at the time of ovulation.
A. Luteinizing hormone or LH helps in the stimulation of the growth of an ovarian follicle in females.
In males, this hormone is known as interstitial cell-stimulating hormone or ICSH and it further affects the Leydig cells of testes.
B. Follicle-stimulating hormone (FSH) is mainly discarded from the anterior part of the pituitary gland.
It helps in the growth of ovarian follicles in females and promotes the growth of the seminiferous tubules in males.
C. Estrogen is the female sex hormone extravasated from ovarian follicles and further stimulate the development of female secondary sex organs.
Hence, ovulation is stimulated by LH and FSH because these hormones stimulate the growth of ovarian follicles and ovum or egg is released from the mature follicles.
So, luteinizing hormone and the follicle-stimulating hormone is responsible for the stimulation of the ovulation.
Hence, the correct answer is option D.

Note: Females near ovulation experience changes in the cervical mucus, and in their basal body temperature. Furthermore, many females experience secondary fertility signs including Mittelschmerz (pain associated with ovulation) and a heightened sense of smell and can sense the precise moment of ovulation.
