Why does every woman have a period and why don t men?

Because every woman has a uterus, and the uterus has menstruation when the uterus functions normally, and the reason why men don't have menstruation is because men don't have a uterus.

Both sexes have special physiological structures. Women have normal shedding of the endometrium that causes menstruation.

Because a woman needs to have children, she must menstruate every month, if a woman does not have menstruation, she will not be able to have children, and men will not have the need to have children, and of course there will be no menstruation.

Women want to have children, men sometimes lose sperm, but sperm loss is much more expensive than menstruation, because a drop of sperm and ten drops of blood, so women's menstruation is normal.

Because every woman has a normal uterus, when the uterus develops to a certain extent, it will shed the endometrium and bleed, and this bleeding is menstruation, while men do not have a uterus, so there is no menstruation.

Why do women have menstruation every month, menstruation is similar to the eggs laid by birds, and women's monthly ovulation is similar to birds laying eggs. Men are mainly responsible for spreading seeds. When an egg is conceived, there will be a chick, and a woman's egg is the same, so menstruation occurs every month.

Women's body structure determines their physiological characteristics, and women have a uterus, so there is this phenomenon. The body of a boy is different from that of a woman. So men don't have that kind of phenomenon as women.

Every woman has a period, but a man doesn't, and that's because of the physiological phenomenon, every woman has a monthly period.

Hello! This is a woman's physiological reaction, there is no reason for this, it is the same as why there are men and why there are women, there is no why, this is the characteristic given to women by the Creator, thank you!

Hello this friend, you are talking about this problem because of the different physiology between men and women. There's nothing strange about it. If you took a physiology class when you were in school, you know.

Hello, the natural phenomenon of male and female physiology is different, there is a difference.

This is a physiological program unique to women and a cycle of fertility

This is a natural phenomenon.

Menstruation is caused by fluctuations in ovarian hormones, which cause the endometrium to periodically shed and bleed. Menstruation marks the beginning of puberty and is a sign of ovarian maturation.

Men have long beards, but don't women also have no beards?

This is a problem that the doctor can do for you...

Because women are responsible for childbearing, ovulation every month can give birth to offspring. Although boys do not have obvious menstrual symptoms, they also have physiological fluctuations from month to month.

Because this is a very normal phenomenon, then your direct physique is different from some of their structures.

This is related to the difference in the physiological structure of male and female students, just like male spermatozoa, but female students will not have it, which is a unique physiological phenomenon of men and women.
