Q. Which one of the following statements is incorrect about menstruation?
A) The beginning of the cycle of menstruation is called menarche
B) During normal menstruation about 40 ml blood is lost
C) The menstrual fluid can easily clot
D) At menopause in the female, there is especially abrupt increase in gonadotropic hormones
Explanation
[Solution from source] Menstrual blood normally does not clot, because fibrinolytic activity in the endometrium dissolves the clots. The first menstruation is called menarche, and about 40 ml of blood is lost per cycle. At menopause gonadotropins rise because the ovaries stop responding. Answer (3).
