Question

Which of the following is a feature of secretory phase of menstrual cycle?

• A. Fall in levels of oestrogen and progesterone
• B. Start of menstrual phase
• C. Bleeding phase
• D. Luteal phase

Answer 1

The correct option is D Luteal phase

The rhythmic reproductive cycle in the female primates is called as the menstrual cycle. The major parts of the menstrual cycle are - menstruation phase (bleeding phase), follicular or proliferative phase and luteal or secretory phase. The luteal phase is the stage where ovulation occurs. During this time progesterone hormone is released by the corpus luteum which thickens the uterus wall for pregnancy. Thus, the correct answer is option D.
