Menstruation and Sexual Activity

Having sexual intercourse during menstruation does not lead to pregnancy as ovulation does not occur during this time. However, such behavior is not advisable, even on the last day of menstruation. This is mainly because women's physical condition is poorer during menstruation, with the cervix dilated, which makes it easier for bacteria to invade and cause gynecological diseases. Even ejaculation outside the body is not allowed. Let's briefly understand this aspect.

1. Having Sexual Intercourse on the Last Day of Menstruation

a. It can lead to prolonged menstruation. During sexual activity, both men and women become excited, and the thrusting of the penis can cause the female reproductive organs to become engorged, leading to increased menstrual flow and prolonged menstruation.

b. It can induce various gynecological infections. During menstruation, the endometrium sheds and bleeds, and the alkaline menstrual blood neutralizes the acidic environment of the vagina, weakening its natural barrier function. Additionally, women's bodies are weaker during this time, and sexual activity can introduce bacteria into the reproductive tract, causing infections and various gynecological inflammations such as endometritis, salpingitis, and pelvic inflammatory disease.

c. It can induce endometriosis. Having sexual intercourse during menstruation can cause uterine contractions due to sexual arousal, which can squeeze fragments of the endometrium into the pelvic cavity, leading to endometriosis.

d. It can induce immune-related infertility. During menstruation, some sperm and semen may enter the female's blood circulation system through small blood vessel ruptures, stimulating the immune system to form sperm antibodies, which can lead to immune-related infertility.

2. Can Ejaculation Outside the Body Cause Pregnancy?

a. During sexual activity, as sexual excitement increases, various glands in the male reproductive system become active, secreting fluids that may contain a certain number of sperm cells. These secretions may leak out of the urethra and enter the female reproductive tract before ejaculation.

b. Many men may not be able to accurately control the timing of ejaculation, and withdrawing the penis too late can easily lead to semen remaining inside or outside the vagina.

c. Semen left around the female vagina, on the male penis, or other areas can potentially enter the female reproductive tract due to various factors.

3. Precautions on the Last Day of Menstruation

a. Adjust your diet. During menstruation, the loss of blood also leads to the loss of plasma proteins, iron, potassium, calcium, magnesium, and other nutrients. Therefore, on the last day of menstruation and within 1-5 days after menstruation ends, it is important to supplement protein, minerals, and blood-enriching foods. Consider foods that have both beauty and blood-enriching effects, such as milk, beef, eggs, spinach, cherries, apples, etc.

b. Increase physical activity. On the last day of menstruation, the body begins to recover gradually. It is advisable to participate in physical exercises such as running, swimming, gymnastics, and other aerobic activities, which can help the body self-regulate and enhance immunity. Additionally, ensure regular sleep patterns, avoid staying up late, and ensure sufficient sleep.

c. Relieve stress appropriately. Menstrual irregularity is closely related to mental stress and emotions. Prolonged exposure to negative emotions and stress can affect the endocrine system, leading to menstrual irregularities. Therefore, it is important to relax, maintain a positive attitude, and avoid dwelling on negative or unpleasant thoughts.
