Young girls, entering their reproductive years, thinking that this month and why they are needed. Menstruation - physiological uterine bleeding, wearing regular and necessary for reproduction of healthy offspring, perform a protective function. There are several theories why we need periods: one of them is a legend, and the other is scientific evidence.

The legend of the appearance of menses

There is a legend that says, why girls go monthly. According to religious giving, women did not have secretions except postpartum period. But changes have occurred as soon as the Virgin Mary gave birth to Jesus.

She asked her maid to take it a shirt with blood stains in the river water. In this case, the girl was not allowed to deploy attire and look at it, but she disobeyed. Mary became angry and ordered that all women, except pregnant and after giving birth, held monthly cleansing procedure using menstrual blood, which was called "shirt".

How things really

If fertilization does not occur, the corpus luteum reduced in size and formed into scar tissue. After this start month, the uterus is cleared, i.e. a functional layer is rejected. This process is accompanied by damage to the small blood vessels that feed the body appears as a result of bleeding from the vagina. Together with the secretions out pieces of endometrium. First menstruation is abundant, and then gradually subsides. Each month, the cycle repeats.

Why can not we do without menstruation

There are several reasons why your period is needed.

Monthly need for regular updating of uterine epithelium, which during each cycle is rejected and then re-formed. This process allows the woman's uterus cleaned monthly, allowing the egg to go out again in the next cycle.

In addition, on the critical day can judge the state of the organism in certain cases:

• If the next menstrual period occurred after the conception of the child, it will show the woman on the likelihood of miscarriage or the presence of other pathologies;
• based on last menstrual period date, you can calculate the ovulation period, to build a calendar of "safe" sex life by using it as a means of protection against unwanted conception;
• during pregnancy planning by the appearance of menstruation can be understood that fertilization has not occurred. This simplifies the troubleshooting process.

Another answer to the question, what is needed monthly in a woman's life, is to ensure the safety function. This version is a science fiction and has no full evidence. It is believed that the mother functional layer has the ability to diagnose the presence of various defects in the fertilized egg cell (this includes serious disorder or chromosomal DNA failures). Further blocked the possibility of implantation of such cells that protects the body from the defect during pregnancy. Ovum dies and torn away from the epithelium. Ie menstruation allegedly helping a woman give birth to a healthy child only.
