The number of spermatozoa ejaculated by a male in one ejaculation is related to the amount of semen as well as the individual’s physical condition. Under normal circumstances, the number of spermatozoa ejaculated by a male in one ejaculation can reach about 100 million to 300 million. In normal men, for example, every 1ml of ejaculate will contain about 20-100 million sperms, and the total amount of ejaculate will be around 3-6ml, so the number of sperms in each ejaculate can be maintained at around 100-300 million. For people who have too much sex, are physically weak and have low testicular reproductive function, the number of sperm contained in each ejaculate will be significantly reduced, and the minimum number of sperm can be less than 40 million, which is also known as oligozoospermia. In some men with azoospermia, a normal amount of semen is ejaculated, but no sperm are detected by laboratory tests or by centrifugal microscopy of the semen. In order to determine the sperm count, it is necessary to go to a specialized hospital for examination.
