The frequency of spermatozoa varies depending on the individual’s physical condition, age, and the amount of sexual stimulation he or she receives. Therefore, there is no clear definition of how often seminal emission is normal. Ejaculation is a condition in which semen flows out of the body without sexual intercourse. Generally, young and middle-aged men who do not have a regular sex life have a relatively high frequency of seminal emission, ranging from 1 to 4 times a month. Middle-aged and old men who have not had regular sex have a relatively low frequency of seminal emission, about 1 to 2 times a month. However, if they are affected by sexual stimulation, the frequency of spermatozoa may increase on the basis of the original. If the frequency of men’s spermatozoa is too high, such as more than eight times a month, and spermatozoa after the emergence of waist and knee pain, anxiety, fatigue and other uncomfortable symptoms, need to pay attention to, should go to the hospital in a timely manner to check, to clarify the cause of the disease, and as soon as possible to carry out targeted treatment.
