Question

State the following statement is true or false.
Menstrual cycle ceases during pregnancy.

• A. True
• B. False

Answer 1

The correct option is A True

If the fertilization occurs and the foetus is implanted in the endometrium, the trophoblastic cells of the developing placenta and secrete the hormone which is the human chorionic gonadotropin. This hormone, like LH, maintain the Corpus luteum and the secretion of progesterone and oestrogen by it. These two check the breakdown of the endometrium of the uterus. The absence of menstrual bleeding is the earliest sign of pregnancy. Fertilization is diploid condition and equatorial division is complete only fertilization occurs.
