Patient's question:
Phimosis and paraphimosis result in the glans not being exposed. I've been confused for a long time and have visited several hospitals.Doctor's answer:
Causes of premature ejaculation, male infertility, and other diseases: Due to the lack of stimulation on the glans mucosa under normal conditions, the nerve sensitivity of the glans mucosa becomes overly sensitive. During sexual activity, the friction between the glans and the vaginal wall leads to immediate ejaculation and sexual pain. Additionally, premature ejaculation, inflammation, and anejaculation can reduce sperm motility and semen viscosity, resulting in infertility.Damages kidney function and induces cancer: Due to inflammation and other factors, the urethral orifice or anterior urethra may narrow, affecting urine metabolism. Bacteria from the foreskin can ascend and infect the kidneys, potentially causing long-term damage to kidney function. Studies have shown that smegma is a carcinogenic substance and is one of the factors leading to penile cancer in men. According to surveys, all patients with penile cancer had phimosis or excessive foreskin.
Endangers female reproductive health and disease recovery: The smegma (residual urine crystals) in the male foreskin is one of the major causes of cervical diseases in women. Smegma is rich in various bacteria, and when introduced into the vagina during sexual activity, it can lead to recurrent and persistent gynecological infections in women. It can also irritate the uterus and induce cervical inflammation, becoming one of the causes of cervical diseases in women.
