Women are in a more sensitive period during menstruation, in which their health condition is poor. Menstrual blood can provide a suitable environment for germs to grow, and bacteria are very easy to breed with menstrual blood, thus leading to pathogens entering into the location of the vagina and uterus because of sex, spreading along the endometrium in many tiny wounds and ruptured small blood vessels.

 

Then, women's fallopian tubes will be infected, resulting in nasal congestion, etc., raising the chances of suffering from endometritis, acute adnexitis, fallopian tube infections and pelvic peritonitis, and other gynecological diseases. This can lead to vaginal bleeding, lower abdominal pain or swelling, increased leucorrhea, cervical congestion and edema, fever, and other aches.

 

 

When menstrual periods come, the endometrium in the pelvic cavity will also periodically shed and cause bleeding, resulting in severe abdominal pains or discomforts, which will increase the risk of menstrual blood countercurrent. If the menstrual blood enters the pelvic cavity by backward flow, the shed endometrium will enter the pelvic with menstrual blood and plant in the pelvic cavity, resulting in endometriosis, causing congestions of the female genitalia, and uterine, thus leading to increased menstrual volume, dysmenorrhea, prolonged menstruation, repeated menstrual periods and other disorders.

 

 

Even with condoms, intense sexual activities can cause inflammation and swelling of the vaginal opening. It is easy for women to get sick because their immunity and anti-viral ability decline during this time (this is the same reason they are especially prone to catching a cold during their periods).

 

The endometrium is shed during menstruation to form a traumatic surface, and the uterine mouth is also slightly open. The endometrial debris will also be squeezed into the pelvis due to the contraction of the uterus during sexual impulses, causing acute attacks of chronic pelvic inflammation in those patients who have had chronic pelvic inflammatory diseases before. 

 

In addition, the acidic environment in the vagina is diluted, and the self-cleaning ability of the vagina is weakened due to the discharge of menstrual blood. During sexual intercourse, male genitalia will bring the bacteria in and infect the endometrium, leading to pelvic inflammatory diseases.

 

 

Women can easily reach orgasm because the endometrium is shedding during menstruation, but the contracted uterine fragments are carried to the fallopian tubes, and even to the woman's abdominal cavity and disc cavity, leading to ectopic endometrium or causing adhesions among the fallopian tubes, the uterus and the pelvic cavity, thus affecting the normal ovulation function of women and causing obstacles to the development and growth of normal eggs.

 

 

When a woman is on her period, male sperm may enter the woman's bloodstream in the damaged area of the uterus due to damage to the mucous membrane of the reproductive tract, causing the woman's immune system to produce anti-sperm antibodies (ASAb). Once this antibody is produced in the woman's body, it will cause the injected sperm to agglomerate during sex, losing its vitality, thus preventing conception, which is called immune infertility.

 

It can be seen above that intercourse during menstruation will increase the risks of diseases in women, especially some gynecological diseases, which will seriously harm women's health and easily lead to infertility. Therefore, it is not recommended to have intercourse during menstruation for the sake of health, family, and fertility!
