A. The beginning of the cycle of menstruation is called menarche
B. At menopause in the female, there is especially abrupt increase in gonadotropic hormones
C. The menstrual fluid can easily clot
D. During normal menstruation about \[40\]mL blood is lost

Answer 1

Hint: Menstruation is the steady flow of blood and mucous tissue from the endometrium through the vagina. Menstrual cycle can be characterized by rise and fall of the hormones. Menstruation is triggered by a drop in progesterone levels and is a sign that pregnancy has not yet taken place. The first period, the period known as the menarche, usually begins between the ages of twelve and fifteen. Menstruation that begins as early as age eight is still considered normal.

Complete answer:
Option A: The beginning of the cycle of menstruation is called menarche: Menarche is the first menstrual cycle or the first menstrual bleeding in a woman. From both a social and medical point of view, it is often considered the central event of female puberty because it signals fertility. Girls go through menarche at different ages.
Hence option A is true and not the correct answer.
Option B: At menopause in the female, there is an especially abrupt increase in gonadotropic hormones: Menopause is the time in a woman's life when her period stops permanently and she is no longer able to have children. Health professionals generally define menopause as when a woman has not had a period for a year. There is also an abrupt increase in gonadotropin hormones during menopause.
Hence option B is true and not the correct answer.
Option C: The menstrual fluid can easily clot: Menstrual blood contains many anticoagulants that help break down thick clots and prevent blood from clotting. This helps maintain free-flow consistency. Menstrual blood also contains plasminogen activators that cause fibrinolysis, which dissolves blood clots.
Hence option C is false and is the correct answer.
Option D: During normal menstruation about \[40\]mL blood is lost: On average, people who menstruate lose almost about \[70 - 80\]ml of fluid which contains about \[35 - 40\]ml of blood per period.
Hence option D is true and not the correct answer.

So, the correct answer is “Option C”.

Note:
The menstrual cycle is a series of natural changes in hormone production and the structure of the uterus and ovaries of the female reproductive system that helps with pregnancy. The ovarian cycle controls the production and release of eggs as well as the cyclical release of estrogen and progesterone. The preparation and maintenance of the lining of the uterus or womb to receive a fertilized egg is governed by the uterine cycle.
