Some people think that phimosis and prepuce are too long and do not hinder sexual life and fertility, so they are not genital diseases. In fact, this view is not scientific. The harm of long foreskin:

1. Penile inflammation:

When phimosis or foreskin is too long, the secretion of sebaceous glands in foreskin can not be discharged, which will produce "scale" Skin scales are suitable for bacterial growth, so it will cause inflammation of the penis head and foreskin. Bacteria can also cause urinary tract infection through urethra. Inflammation at the urethral orifice can lead to stricture of the urethral orifice after healing, resulting in dysuria.

2. Cancer risk:

Excessive prepuce and phimosis may induce penile cancer. Modern scientific research shows that scale is a carcinogen. If you share a room with your wife, it will also bring scale into the vagina, stimulate the uterus and induce cervical cancer.

3. Renal function damage:

Due to inflammation of penis, urethral orifice or anterior urethra can be narrowed, which leads to dysuria. Long-term dysuria will damage the function of the kidney.

4. Hinder penis development and affect sexual harmony;

Phimosis will affect the growth and development of penis, and adults will affect their normal sexual life because of too long foreskin or phimosis. In severe cases, the glans penis will be edematous due to poor blood flow, and even the glans penis will be necrotic.
