User consultation: yesterday, I found that my foreskin was red and swollen after masturbation. Maybe it's too big. Excuse me, doctor, how should I deal with this problem? The doctor replied: Your symptoms now are mainly local minor injuries caused by masturbation violence, and you don't pay attention to cleaning. Remind you not to masturbate too much. At the same time, I suggest you go to the hospital to check whether there is too long foreskin or other infections. If there is a problem of too long foreskin, you should go to a regular male hospital for foreskin surgery in time. If there are other infection problems, we should also actively check and actively treat them. What are the hazards of long foreskin? (1) Hinder penis development and affect sexual harmony: phimosis will affect penis growth and development. In adolescence, because the penis head is tightly wrapped by the foreskin, it can't be stimulated by the outside world, and the development of the penis head is greatly inhibited, which leads to the obvious reduction of the circumference of the penis crown after the sexual organs mature, which affects sexual pleasure. Adults will affect their normal sexual life because their foreskin is too long or phimosis. Especially for men whose foreskin is too small, it can't be recovered after the foreskin is turned up, and the foreskin is tightly stuck in the coronary sulcus, forming incarcerated phimosis, which is not very painful. In severe cases, the glans penis will be edematous due to poor blood flow, and even the glans penis will be necrotic. (2) Risk of cancer: The foreskin is too long, and phimosis may induce penile cancer. Modern scientific research shows that echinococcosis is a carcinogen. According to the survey, 85%-95% of patients with penile cancer are phimosis or redundant prepuce. The phimosis and foreskin are too long, which not only affects the health, but also brings scale into the vagina, stimulates the uterus and induces cervical cancer if you sleep with your wife. (3) Renal function damage: Due to penis inflammation, urethral orifice or anterior urethra can be narrowed, resulting in dysuria. Long-term dysuria will damage the function of the kidney. (4) Penile inflammation: There are abundant sebaceous glands in the foreskin, which can secrete a lot of sebum. When phimosis or foreskin is too long, the secretion of sebaceous glands in foreskin cannot be discharged, and the sediment in sebum and urine synthesizes cheese-like smelly "skin 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. What if the foreskin is too long? At present, Guangzhou Men's Hospital performs circumcision for patients with redundant prepuce, which is based on the cutting-edge minimally invasive technology, adopts a professional all-digital reproductive plastic surgery system in the field of plastic surgery, is operated by a first-class minimally invasive medical doctor in a professional reproductive plastic surgery center, cooperates with the use of advanced materials, advanced technology and a professional laminar ultra-clean aseptic operating room, and adopts a radical and one-step method to remove patients' redundant prepuce painlessly and minimally invasive.
