Question

Which one of the following statements is incorrect about menstrual cycle?

• A. The first menstruation begins at puberty and is called menarche
• B. Lack of menstruation may also occur due to some environmental factors like stress and poor health
• C. Corpus luteum secretes large amounts of progesterone which is essential for maintenance of endometrium
• D. In absence of fertilisation, corpus luteum degenerates in luteal phase and new follicles start developing immediately

Answer 1

The correct option is D In absence of fertilisation, corpus luteum degenerates in luteal phase and new follicles start developing immediately

In the absence of fertilisation, the corpus luteum degenerates in luteal phase. This causes disintegration of the endometrium leading to menstruation, marking a new cycle, not developing new follicles immediately.
