If a man has the urge to ejaculate during sex, a portion of the sperm triggers the ejaculation phenomenon but is not expelled from the body because the man contracts the urethral sphincter and the sperm cannot be expelled. The reflux of semen can lead to inflammation of the prostate gland, and if more serious, can lead to prostatitis and infection of the male reproductive system, leading to inflammation of the vas deferens or vesiculitis. In the future, if the vesiculitis occurs during the couple’s life, there is a risk of hematospermia, which can repeatedly aggravate the urinary tract infection and cause bilateral obstruction of the vas deferens. If it is more serious, it can also cause the sperm to be unable to discharge on its own, resulting in infertility. The actual fact is that if you’ve got the urge to ejaculate in the course of conjugal life, try not to inhibit it. If the nerve sensitivity is too strong due to premature ejaculation, and there is uncontrollable self-ejaculation, the patient can apply topical time-delay medication for a period of time and wait for the local nerve of the glans to gradually desensitize to restore the normal ejaculation time.
