In the early stages of pregnancy, masturbation has a great impact on the patient, and the danger is mainly reflected in the following two aspects. First, it may cause miscarriage. In the early stages of pregnancy, the relationship between the embryonic tissue and the uterine wall is not very close. If the patient masturbates to orgasm, it may cause the contraction of the muscles of the whole body, including the contraction of the uterine muscles. If the uterine muscle contraction may cause the patient’s embryo to be expelled from the body under the action of systolic pressure, that is, the situation of miscarriage. Secondly, masturbation in the early stages of pregnancy may lead to infection. The vaginal resistance of the patient after pregnancy is relatively low, if the patient masturbates without proper sanitary disinfection, during the process of masturbation there may be infections, such as vaginitis or pelvic inflammatory disease.
