alleryIn the female, the luteinizing hormone (LH) from the anterior pituitary mainly brings about:
AReabsorption of water from kidney tubules
BSperm formation in the germinal epithelium
COvulation and formation of the corpus luteum
DConversion of glucose into stored glycogen
Answer & Solution
Correct answer: C. Ovulation and formation of the corpus luteum
1. LH is a gonadotropic hormone of the anterior pituitary.
2. In females it causes ovulation, the rupture of the mature Graafian follicle.
3. It also drives development of the corpus luteum and production of estrogen and progesterone.
4. Water reabsorption is an ADH role and glycogen storage is an insulin role, so they are wrong.
5. Sperm formation is the male FSH role on the germinal epithelium, not the female LH action, so it is ruled out.
6. Hence in females LH triggers ovulation and corpus luteum formation, not the male or kidney roles.
