Luteinizing Hormone (LH) ________

Question

Luteinizing hormone (LH) ________.
A) is released by the corpus luteum
B) is secreted by Sertoli cells
C) stimulates ovulation
D) stimulates follicle growth during the first week of the menstrual cycle

Accepted Answer

LH is responsible for triggering ovulation in females by causing the mature follicle to rupture and release the egg.

Answer: D 
 Follicle-stimulating hormone (FSH) is primarily responsible for stimulating follicle growth during the first week of the menstrual cycle. While LH also plays a role in follicle development, it is primarily involved in triggering ovulation. Therefore, Choice D is incorrect.

Thus, the best choice is C alone (stimulates ovulation).
