What Are the Consequences of Having Sex During Menstruation?
Menstruation is a normal physiological process in women. During this time, the body undergoes certain changes compared to usual, and immunity tends to decline. Because the endometrium sheds, the cervical os opens, and blood is discharged from the vagina during menstruation, sexual intercourse is not advisable under these conditions. So, what are the consequences of having sex during menstruation? The following section addresses this question.

Consequences of Sexual Intercourse During Menstruation
During menstruation, women’s immune function is relatively suppressed, and menstrual blood serves as an excellent medium for bacterial growth. Thus, engaging in sexual intercourse at this time increases the risk of developing gynecological infections—including vaginitis, salpingitis, adnexitis, and pelvic inflammatory disease (PID). In some cases, tubal inflammation and subsequent obstruction may even lead to infertility. Additionally, pelvic congestion commonly occurs during menstruation, often causing lower back and sacral discomfort or pain; sexual activity during this period may exacerbate such symptoms. Women with dysmenorrhea may also experience intensified menstrual pain. Moreover, intercourse during menstruation is not only inconvenient but also unhygienic, as menstrual blood promotes bacterial proliferation—posing infection risks not only to the woman but also potentially to her male partner, thereby adversely affecting both individuals’ health.

Knowledge Extension: Key Precautions During Menstruation
1. Limit intake of spicy, stimulating, and greasy foods, as well as raw, cold, or “cold-natured” foods. Instead, favor warming and nourishing foods—such as red dates and brown sugar—which help alleviate menstrual discomfort and support healthy blood production.
3. Avoid emotional stress and mood fluctuations, as these can disrupt normal menstrual function. Therefore, maintaining emotional stability is essential during menstruation. Sexual intercourse should also be avoided during this period to prevent infection; this precaution must be observed carefully.
The above outlines the potential consequences of sexual intercourse during menstruation. We hope this information is helpful to you.
