Question

Which of the following is the most likely reason for the absence of a menstrual period after a regular menstrual cycle?

• A. Maintenance of the hypertrophic endometrial lining
• B. Fertilization of ovum
• C. Maintenance of high concentration of sex hormones in the blood stream
• D. Retention of well-developed corpus luteum

Answer 1

The correct option is B Fertilization of ovum

Menstrual flow takes place only if the ovum is not fertilised.

When the ovum is fertilised the endometrial linning is maintained by the secretion of progesterone and estrogen, which prevents menstruation.
