Question

Select the correct option regarding various events occurring during menstrual cycle.

• A. Proliferative phase: rapid regeneration of endometrium and ovulation.
• B. Secretory phase: development of corpus luteum and increased production of progesterone.
• C. Menstruation: breakdown of myometrium
• D. Ovulation: the levels of LH are significantly low.

Answer 1

The correct option is B Secretory phase: development of corpus luteum and increased production of progesterone.

Secretory/luteal phase is the post ovulatory phase where development of corpus luteum takes place and thereby, the secretion of progesterone increases.

During the proliferative/follicular phase, rapid regeneration of endometrium takes place but there is no ovulation during this phase.

Menstruation is the breakdown of uterine endometrium.

During ovulation, the levels of LH are very high and that causes ovulation.
