Too long foreskin is a phenomenon that many male friends have, and many people don't know much about its harm. Director Guo pointed out that too long foreskin is not only harmful to yourself, but also harmful to your partner's health, so you should know more about the harm of too long foreskin to yourself and your partner.

The foreskin means that it cannot leak out when it is not erect, or it is wrapped by more than 2/3. The phimosis is more serious than the foreskin. Theoretically, it means that it cannot leak out during erection, or it is wrapped by 2/3 after erection. The phimosis of prepuce not only affects the growth and development (length and diameter), but also is the chief culprit of prostatitis, urinary tract infection, premature ejaculation, impotence and female reproductive diseases.

1. Affect the development of length and diameter: In adolescence, because the head is tightly wrapped by the foreskin, it can't be stimulated by the outside world, and the development is inhibited, resulting in a smaller crown diameter after maturity. In adulthood, if the foreskin is embedded with phimosis, it can lead to necrosis.

2. It is easy to cause urogenital inflammation: the rich sebaceous glands in the foreskin produce a lot of secretions, which cannot be discharged by the foreskin and accumulate into scales to parasitize many pathogenic bacteria. Bacteria invading the urethra can cause urinary tract infection, which can lead to dermatitis, inflammation and urethritis, and also increase the infection of genital warts, herpes and other sexual diseases.

3. Causes impotence, premature ejaculation, male infertility and other diseases: Because the mucosa is usually stimulated less, the nerve feeling of the mucosa is too sensitive, and the contact friction will be vented during sexual life, which will also cause pain during sexual intercourse. It will also cause infertility due to premature ejaculation, inflammation, impotence, and no ejaculation.

4. Renal function is impaired, which induces cancer: urethral stricture or anterior urethral stricture caused by inflammation affects urine metabolism, and bacteria in the foreskin will infect the kidney, which will damage the function of the kidney for a long time. Studies have shown that echinococcosis is a carcinogen and one of the factors leading to cancer in men. According to the survey, 85%-95% of cancer patients are phimosis or redundant prepuce.

5. Endangering women's reproductive health and disease rehabilitation: male skin scales (residual urine crystals) are one of the important causes of female cervical cancer. Skin scales are covered with all kinds of bacteria. Long-term treatment will lead to repeated infections of female gynecological diseases, stimulate the uterus and induce cervical cancer, which is an important reason for the malignant transformation of female cervix.
