Question

Onset of pregnancy

• A. Stimulates testosterone secretion
• B. Inhibits further ovulation
• C. Leads to degeneration of ovary
• D. Inhibits fusion of egg and sperm nuclei

Answer 1

The correct option is B Inhibits further ovulation

During menstruation cycle, rapid secretion of LH induces rupture of Graafian follicle and thereby the release of an ovum (ovulation). The ovulation (ovulatory phase) is followed by the luteal phase during which the remaining parts of the Graafian follicle converts into the corpus luteum if fertilization occurs. The corpus luteum secretes large amounts of progesterone which maintains the events of pregnancy. During pregnancy, all events of the menstrual cycle stop and there is no menstruation and ovulation

So, the correct answer is 'Inhibits further ovulation'
