Question

Ovulation occurs -

• A. At the mid secretory cycle
• B. Just before the end of the secretory phase
• C. At the beginning of the proliferative phase
• D. At the end of the proliferative phase

Answer 1

The correct option is D

At the end of the proliferative phase

Ovulation takes place at the end of proliferative phase of menstrual cycle. During this phase, the follicle stimulating hormone (FSH) secreted by the anterior lobe of the pituitary gland stimulates the ovarian follicle to secrete estrogen. Estrogen stimulates the proliferation of the endometrium which is accompanied by an increase in the number of uterine glands and blood vessels. This phase ends when the ovarian follicle ruptures releasing the ovum.
