During Which Process Does the Shedding of the Endometrium Occur

Question

During which process does the shedding of the endometrium occur?
A) menstruation
B) intercourse
C) ovulation
D) fertilization

Accepted Answer

The shedding of the endometrium occurs during menstruation, which is the monthly shedding of the uterine lining that occurs when fertilization does not occur. Intercourse and fertilization do not involve shedding of the endometrium, and ovulation is the release of an egg from the ovary, not the shedding of the uterine lining.
