How long you have to abstain from sex in the morning when your morning erection disappears cannot be generalized and needs to be judged in the context of the patient’s specific situation. In fact, the absence of morning erections in the morning does not necessarily require abstinence. This is because adult men usually experience 3-5 erections each night while sleeping, each lasting anywhere from 5-10 minutes. If a man’s penis is still erect before he wakes up, he will wake up in the morning with a penile erection, but the vast majority of nocturnal penile erections will not be noticed. So even if there is no morning erection, it does not mean that there is a problem with sexual function, and if there is no problem, there is no need to deliberately abstain from sex. However, it should be noted that if the loss of morning erection is due to excessive masturbation, declining hormone levels, inflammatory infections of the genitourinary system and other factors, then proper abstinence is necessary, and the specific duration of abstinence is recommended to be adjusted flexibly according to one’s recovery. In short, patients do not necessarily need abstinence in the morning without morning erections, and there is no need to worry excessively. However, if the disappearance of morning erection lasts for more than six months, or if there are problems such as difficulty in erection and poor hardness during sex, it is recommended to seek timely medical attention from the urology department to clarify the cause and then actively treat it.
