Introduction
In general, "同房" refers to sexual intercourse, and "完" indicates completion. It is not recommended to engage in sexual activity when the menstrual period is about to end. Even near the end of menstruation, the cervix remains slightly open. At this time, engaging in sexual intercourse allows pathogens such as bacteria and viruses to easily enter the cervix through the vagina, potentially causing ascending infections of the endometrium, fallopian tubes, or even the pelvic cavity, leading to conditions such as endometritis or pelvic inflammatory disease.

Generally speaking, "tong fang" refers to sexual intercourse, and "wan" indicates completion. Sexual intercourse is not recommended when the menstrual period is about to end. Detailed explanation is as follows:

When the menstrual period is nearly over, engaging in sexual intercourse usually is not recommended. Even if the period is almost finished, the cervix remains slightly open. At this time, engaging in sexual activity may allow pathogens such as bacteria and viruses to enter the cervix through the vagina, subsequently traveling upward to infect the endometrium, fallopian tubes, or even the pelvic cavity, leading to endometritis or pelvic inflammatory disease. These infections may cause symptoms such as abdominal pain, fever, and abnormal vaginal discharge, and long-term recurrent infections could negatively affect fertility.

During sexual intercourse, stimulation of the genital organs may cause uterine contractions. These contractions might cause the endometrium, which has not yet fully healed, to bleed again, thereby prolonging the menstrual period. It is recommended to wait one to two days after the completion of the menstrual period before engaging in sexual intercourse.

Women are advised to maintain good external genital hygiene and follow a light diet during menstruation to promote recovery.
