Introduction
Having sex during menstruation can stimulate uterine contractions, which may increase menstrual flow or lead to prolonged, irregular bleeding. During menstruation, resistance is lowered and the endometrium sheds, leaving an open surface; sexual intercourse can allow pathogenic bacteria to enter the uterine cavity along with menstrual blood, potentially causing gynecological conditions such as pelvic inflammatory disease or endometritis. Sexual activity during menstruation may also cause uterine contractions and retrograde menstruation, leading to endometriosis.

Menstrual period refers to the time of menstruation. Having sex during menstruation can cause various health risks, such as increased menstrual flow, retrograde infection, or endometriosis. In severe cases, it may impair fertility. Therefore, sexual intercourse during menstruation should be strictly avoided. Specific risks are analyzed as follows:

1. Increased Menstrual Flow

Sexual intercourse during menstruation may stimulate uterine contractions. Accelerated contractions can lead to heavier menstrual bleeding or prolonged spotting.

2. Retrograde Infection

During menstruation, the body's resistance decreases and the endometrium sheds, leaving an open surface. Sexual activity may allow pathogens to enter the uterine cavity along with menstrual blood, leading to gynecological infections such as pelvic inflammatory disease or endometritis.

3. Endometriosis

Sex during menstruation causes uterine contractions, which may result in retrograde menstrual flow and implantation of endometrial tissue outside the uterus, leading to endometriosis.

In addition, having sex during menstruation may also lead to other harms such as immune infertility. Sexual activity should be strictly prohibited during menstruation, and proper hygiene and care must be maintained. If intercourse does occur during this period, prompt medication should be used to prevent infection.
