Question

What occurs before ovulation?

• A. A rise in the levels of progesterone only
• B. A rise in the levels of oestrogen only
• C. A rise in the levels of oestrogen and progesterone
• D. A fall in oestrogen levels only

Answer 1

The correct option is B A rise in the levels of oestrogen only

Ovulation is the release of an ovum from the ovaries at around day 14 of the menstrual cycle. This event is triggered by an increase in the levels of luteinizing hormone, called the LH surge. In addition to LH, the levels of estrogen also increase around ovulation.

So, the correct answer is 'A rise in the levels of oestrogen only'.
