Question

how and when ovulation occur?​

Answer 1

Answer:

It occurs at about day 14 of a 28-day menstrual cycle. Specifically, ovulation is the release of the egg (ovum) from a woman’s ovary.

Each month, between days six and 14 of the menstrual cycle, follicle-stimulating hormone causes follicles in one of a woman’s ovaries to begin to mature. However, during days 10 to 14, only one of the developing follicles forms a fully mature egg. At about day 14 in the menstrual cycle, a sudden surge in luteinizing hormone causes the ovary to release its egg. The egg begins its five-day travel through a narrow, hollow structure called the fallopian tube to the uterus. As the egg is traveling through the fallopian tube, the level of progesterone, another hormone, rises, which helps prepare the uterine lining for pregnancy.

Answer 2

Answer:

When the amount of estrogen reaches its upper threshold, the egg is ready for release. The brain then produces a surge of luteinizing hormone (LH), triggering ovulation. The release of the egg from the follicle and ovary happens about 24 hours later (10–12 hours after LH peaks) (13, 17).It occurs at about day 14 of a 28-day menstrual cycle
