Why does menstruation occur?
Answers
Answer:
When females hit the puberty and become sexually matured then after each 28 days either ovary releases an egg when egg comes to uterus by fallopian tube uterus prepares itself and develops a cushion of blood caplliaries so that foetus can get nutrition and egg in uterus wait for sperm to get fused and fertilised for 2-4 days but if there is no sperm it sheds off through vagina with egg and thick layer of blood caplliaries. This causes bleeding in women which is called menstruation.

Answer:
The menstrual cycle occurs due to the rise and fall of hormones. This cycle results in the thickening of the lining of the uterus, and the growth of an egg, (which is required for pregnancy). ... If pregnancy does not occur, the lining is released in what is known as menstruation.
