During ejaculation, why are so many sperm cells released?

The number of reproductive cells in men and women

Reporting from Live Science, the average man produces approximately 525 billion sperm cells over a lifetime and excretes at least one billion per month. A healthy adult male can release between 40 million and 1.3 billion sperm cells in one ejaculation.

In comparison, women are born with an average of 2 million egg follicles, the sacs that reproduce the egg. At puberty, about 450 eggs mature for fertilization are shed during menstruation.

Every man has a different number of sperm cells

Reporting from the Ovulation Calculator, the number of sperm per man is influenced by the size of the testicles (testicles). The larger the male testicles, the greater the number of sperm cells produced. Because in the larger testes there are more spermatogonia which will divide and develop to produce new sperm.

The sperm spends its time passing through the epididymis to develop a sperm tail that helps it move to reach the egg later.

Why are many sperm cells released during ejaculation?

In women, the large number of unfertilized eggs will shed through menstruation (which of course is not just a drop or a drop of blood). Well, this concept is actually somewhat similar to male ejaculation. Sperm will "decay" in large quantities when a man ejaculates.

When ejaculation occurs, the approximately 250 million sperm stored in a man's body are pushed by muscle contraction through tubes called the vas deferens through the penis. This muscle contraction is called an orgasm. There are usually several bursts from the tip of the penis during orgasm. The first burst, the majority contain sperm cells. Then, the second and third bursts contain the prostate gland and semen produced by the cement sac glands (seminal vesicles).

The more sperm cells released, the greater the chances of conception

Basically, the main function of sperm cells is reproduction. So, the sperm cell must be able to fertilize a woman's egg. This is not easy, considering the vagina is an acid environment and unfortunately quite deadly for sperm cells. The acidity of the vagina itself is actually a woman's body defense from bacteria and viruses. A few minutes after ejaculation, only the fastest and healthiest sperm can penetrate the vagina, up to the cervix, and reach the egg.

Among the many sperm cells that are released, only one is needed to fertilize an egg. So, there was competition between sperm. Sperm speed greatly affects sperm resistance in an acidic environment that kills sperm.

The success of one sperm in fertilizing an egg will create a fetus later. Too many or the accumulation of sperm cells in one egg (polyspermy) can cause extra chromosomes that endanger the sex determination of the fetus, so that the fetus ends up having a miscarriage.

So in short, the more sperm cells that are released, the greater the chance of fertilizing an egg. Imagine if only one sperm cell is released in one ejaculation. This could hamper the survival of mankind because of the difficulty of reproduction.
