You cannot run out of sperms
DURING ejaculation, the epididymis and vas deferens muscles contract to propel the sperm into the ejaculatory duct. Here the sperm is joined with the secretions of the seminal vesicles and prostate gland (which contribute the bulk of the seminal fluid) to form the semen.
DURING ejaculation, the epididymis and vas deferens muscles contract to propel the sperm into the ejaculatory duct. Here the sperm is joined with the secretions of the seminal vesicles and prostate gland (which contribute the bulk of the seminal fluid) to form the semen. The powerful muscles surrounding the base of the urethra then cause the semen to squirt out of the penis at the time of orgasm.
Semen and urine never mix in a healthy male because the bladder sphincter muscle contracts during stimulation, thus closing down the exit from the bladder to the urethra during ejaculation.This prevents urine from leaking out of the bladder during sex and also prevents semen from accidentally going backward into the bladder.
About one teaspoon of semen spurts out of the penis. Sperms account for only about 2 to 3% of semen. Most of it consists of semen, which provide a vehicle for the sperm into the vagina.
A normal ejaculation contains 200 to 500 million sperms. They are very tiny. If one average ejaculation filled an Olympic size swimming pool, each sperm cell would still be smaller than a goldfish. Sperms are the smallest living cells in the human body - and the egg the largest.
Sperms are designed so that they can deliver their contents - the male genetic material - to the egg. This is why they are designed like projectiles - the male DNA is in the chromosomes in the sperm head nucleus, and the tail propels the sperm up towards the egg.
Sperms are also very fragile. Men make so many because very few survive the swim through the female reproductive system to fertilize an egg. Perhaps the reason for this is to get the fittest possible.
Unfortunately, you cannot “store up†sperms. If ejaculation does not occur for many days, the sperms in the reproductive ducts simply die. This is why a sperm count done after many days of abstinence shows a high number of dead or immotile sperms.
But just like you cannot store your sperm, you cannot run out of sperms. The body keeps making them throughout life.
