Normal male semen volume is 2~6ml. If sex is more frequent, it is normal for a man to ejaculate more semen volume once or twice in the section, and less and less after arrival. If 1 ejaculation can fill the condom’s sperm storage sac, it is more than 2 ml. If there is no ejaculation for several days, weeks or even longer, and the semen volume is still less than 1.5 ml, it is too little semen volume, which may lead to infertility. Low semen volume is usually a problem with the seminal vesicles and prostate gland. It is best to have a semen examination if you do not discharge semen for 3 to 5 days. Excessive semen may also be the result of excessive seminal plasma secretion, which is a manifestation of seminal vesicle inflammation, when the vitality of sperm decreases, which may also affect fertility.
