How many times the seminal vesicles can be emptied refers to the emptying of the semen inside the seminal vesicles, and the exact number of times varies from person to person. The semen in the seminal vesicles is produced continuously and is usually not emptied. However, if a man has sex too often or ejaculates continuously, the amount of semen discharged will gradually decrease, or even the case of twitching but no semen ejaculated from the urethra. The male body will produce several large quantities of sperm every day, which will decrease after continuous ejaculation. If there is no sex within a few days, the amount of semen will gradually return to the normal level. It is recommended that men pay attention to appropriate exercise in normal times, which can enhance physical fitness, and pay attention to avoid excessive sexual life, so as not to cause damage to the body.
