It is not difficult for both men and women to know these three common knowledge of gynecology.

As a sexual partner, if you don't even understand the basic gynecological knowledge, first, you can't have sex during your menstruation. Women have a few special days of menstruation every month, which can stimulate the inner wall of the uterus, or lead to increased bleeding, and are easy to be infected during sex. Bacteria in women's vaginas can also be transmitted to men through sexual intercourse. Men must remember not to share a room during the menstrual period. Second, the safe period is not necessarily safe. Every menstrual cycle of women is divided into menstrual period, ovulation period and safe period. The period from the day when menstruation is clean to the day before ovulation begins is the safe period before ovulation. Many men have absolute confidence in the safe period and believe that they will not get pregnant even if they have sex without wearing a condom. Some women's ovulation is not so regular, the effects of some endocrine diseases will also change the timing of ovulation, and some women are extremely excited during sexual intercourse will lead to early ovulation, women may ovulate at any time of the month, leading to ovulation fluctuations.

Seeing this topic, many male classmates will wonder: why should men understand the common sense of gynaecology? Does it have anything to do with us? It really does matter, you know, many diseases are caused by sexual transmission, as a sexual partner if you do not even understand the basic gynecological knowledge, it may cause big trouble. What common sense of gynaecology should we know? Let's see.

First, you can't share a room during your menstruation.

This is the most basic. Women have a few special days of menstruation every month, usually 3-7 days, and men should put up with them. During the menstrual period, the female endometrium falls off, and some blood vessels are open and exposed. if you have sex at this time, it will stimulate the inner wall of the uterus, or it will lead to an increase in bleeding and prolonged menstruation, and the immunity of women at this time is low. It is easy to be infected during sex, causing infection, the most common is pelvic inflammation.

For men, it is not a good thing, menstrual sex, women's vagina bacteria can also be transmitted to men through sexual intercourse. Therefore, men must remember not to have sex with each other during menstruation, for the sake of their partner and for themselves.

Second, the safe period may not be safe.

Each menstrual cycle of women is divided into menstrual period, ovulation period and safe period. The period from the day when menstruation is clean to the day before ovulation begins is the safe period before ovulation. Many men have absolute confidence in the safe period and believe that they will not get pregnant even if they have sex without wearing a condom. In fact, gynaecologists said that the safe period is not necessarily safe, and some women's ovulation is not so regular. in addition, the effects of some endocrine diseases will also change the timing of ovulation, and some women will be extremely excited during sexual intercourse, which will lead to ovulation in advance. These things happen from time to time.

Women may ovulate at any time of the month, subject to changes in individual endocrine, emotional, environmental and other factors, leading to ovulation fluctuations, and even more ovulation. Examples of safe periods are also common in life, so it is recommended not to blindly believe in safe periods.

Third, if you can't get pregnant for many years, it's not necessarily a woman's problem.

Many people have been unable to get pregnant for many years, and many people put the blame on the woman. There are many reasons for infertility. These reasons have nothing to do with women:

1. Men take drugs for a long time, which cause permanent damage to sperm, such as various hormone drugs, blood pressure lowering drugs and so on.

2, sperm motility is not good, some men smoke too much alcohol and tobacco, work pressure, often stay up late, resulting in lack of sperm motility, and even lead to sperm deformity

3. Obesity may gradually lead to the decrease of sperm survival rate and motility, which may lead to male infertility.

4. the abnormal chromosome of the man, the abnormal number and structure of chromosome can easily lead to multiple miscarriages, which can increase the probability of conception through the third generation of test-tube babies.
