Question

What hormone stimulates ovulation?
a. LH
b. FSH
c. estrogen
d. progesterone

Answer 1

LH (Luteinizing Hormone) is the hormone that triggers ovulation. It is part of a complex hormonal interplay that includes GnRH from the hypothalamus and the pituitary-produced hormones LH and FSH.

Step-by-step explanation:

The hormone that stimulates ovulation is LH (Luteinizing Hormone). Luteinizing Hormone is critical in the reproductive phase for both males and females. It is regulated by the secretion of several hormones, including GnRH (Gonadotropin-Releasing Hormone), which is produced by the hypothalamus. The regulation of LH and FSH (Follicle-Stimulating Hormone) is a complex process involving feedback mechanisms with other hormones such as estrogen and progesterone.

During the female reproductive cycle, LH and FSH, which are produced in the pituitary gland, stimulate the development of ova in the ovaries and the production of estrogen and progesterone. After ovulation, which is induced by a surge in LH, the corpus luteum forms and begins to secrete increasing amounts of estrogen and progesterone, which prepare the endometrial lining of the uterus for potential implantation. With the onset of menopause, the follicles cease to respond to these stimulatory hormones.

Answer 2

LH and FSH.

Step-by-step explanation:

Ovulation may be defined as the process of release of one egg from the ovary each month. This ovulation generally occurs at the 15th or 16th day of the menstrual cycle.

The hormone that triggers ovulation is luteinizing hormone and follicle stimulating hormone. These hormones at the highest peak at the time of ovulation.

Thus, the correct answer is option (a) and (b).
