Ovulation occurs around the midpoint of the menstrual cycle (approximately day 14), triggered by a surge in luteinizing hormone (LH) due to elevated oestrogen levels. This LH peak causes the Graafian follicle to rupture, releasing the ovum.

1. Ovulation happens at the start of the cycle.
2. Ovulation happens at the end of the cycle.
3. Ovulation happens around the middle of the cycle.
4. Ovulation does not occur during the cycle.

Correct answer: Ovulation happens around the middle of the cycle.

Solution

Ovulation typically occurs in the middle of the menstrual cycle, around the 14th day in a 28-day cycle, triggered by the LH surge. This is a well-established fact in human reproduction.
