What is the Menstruation cycle in human females?

Menstruation is a process that females go through with the onset of puberty. During this process, the female bodies prepare themselves for a potential pregnancy. Regular cycling of hormones takes place in the female reproductive system.

One ovum is released by the ovaries into the fallopian tube once in 28-30 days. Hence, the length of the menstrual cycle is about 28 days. However, it varies for every woman. The release of an egg from the ovary is known as ovulation.

In the absence of sperm, pregnancy does not happen and the egg along with the thick lining of the uterus and blood vessels is shed which causes bleeding in women. It is known as menstruation or the menstrual cycle.

Human females (or women) have the following menstrual cycles:

After reaching adolescence, a female's ova begin to mature and are released by the process of ovulation once every 28 days, or once a month.

Before ovulation, the uterine lining thickens and swells in preparation for receiving the fertilized egg. Menstrual flow refers to the flow of blood and tissue from the vagina that occurs if the egg is not fertilized. If this happens, the uterine or womb lining ruptures loses its lining and leaves the body through the vagina.

This starts on the fourteenth day after ovulation and often lasts three to five days.

The uterus begins preparing for the fertilized egg after this flow ends. The identical series of circumstances repeat itself if it does not get the fertilized egg.

Menstruation or periods typically begin between the ages of 11 and 14 and last until menopause, which occurs at around the age of 51.

Acne, bloating, sore breasts, exhaustion, food cravings, mood swings, irritability, lower back discomfort, headaches, and lethargy are typical indications and symptoms of this cycle.
