Question

why does mensuration occurs​

Answer 1

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.
