It is recommended to wear condoms during intercourse during pregnancy, wearing condoms is conducive to reducing the chances of infection, preventing disease transmission, reducing the risk of miscarriage, can maximize the protection of pregnant women and fetuses: 1, reduce the chances of infection: increased secretions during pregnancy, the body’s immune function is in a state of inhibition, sugar metabolism rate is poor, easy to breed mold, suffering from genitourinary system infections, intercourse during pregnancy wearing condoms can reduce body fluids The condom can reduce contact with body fluids, reduce the chance of bacterial infection, wearing condoms can effectively prevent inflammatory infections; 2, to prevent disease transmission: condoms can also prevent men from transmitting AIDS, syphilis, condyloma acuminata, gonorrhea, etc. to pregnant women to avoid maternal and fetal infection; 3, to reduce the risk of miscarriage: male semen contains a large number of prostaglandins, intercourse into the female vagina, participate in a variety of metabolic activities, easy to stimulate the uterus contraction This can lead to abdominal pain and even miscarriage. Wearing a condom can prevent semen from being ejaculated directly into the woman’s vagina and reduce the risk of miscarriage. Intercourse is not recommended in early pregnancy (before 12 weeks of pregnancy) and after late pregnancy (28 weeks of pregnancy). Because the body is weak in early pregnancy, the resistance is obviously reduced, and the embryo is unstable, intercourse at this time can easily stimulate the uterus and cause abnormal contractions, and in serious cases, signs of miscarriage. In the late pregnancy, the uterus increases significantly and the abdomen expands, so if intercourse during this period presses on the abdomen, it will lead to high intrauterine pressure and fetal hypoxia, or stimulate the uterus to cause contractions, thus increasing the risk of preterm delivery.
