When having sex and reaching ejaculation, many sperm cells are released even reaching 250 million in number. Even though only one sperm cell is needed to fertilize sperm cells. Why are so many sperm released during ejaculation? Consider the following review.
Number of reproductive cells in men and women
Reported from Live Science, the average man produces approximately 525 billion sperm cells over a lifetime and spends at least one billion per month. A healthy adult man 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, that is, the bag that reproduces the egg cell. At puberty, about 450 mature eggs for fertilization are shed during menstruation.
Every man has a different number of sperm cells
Reporting from the Ovulation Calculator, the number of sperm counts each man is influenced by the size of the testicles (testicles). The greater the male testicles, the more 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 time passing through the epididymis to develop a tail of sperm that helps it move to reach the egg later.
Why are many sperm cells released during ejaculation?
In women, the number of unfertilized eggs will collapse through menstruation (which is certainly not just a drop or a drop of blood). Well, this concept is actually rather similar to male ejaculation. Sperm will "collapse" in large numbers when men ejaculate.
When ejaculation occurs, about 250 million sperm stored in a man's body are driven by muscle contraction through a tube called the vas deferens through the penis. This muscle contraction is called orgasm. Usually there are several bursts of the tip of the penis during orgasm. The first burst, the majority contains sperm cells. Then, the second and third bursts contain the prostate gland and semen produced by the gland of the semen bag (seminal vesicles).
The more sperm cells are released, the greater the chance of fertilization
Basically, the main function of sperm cells is reproduction. So, sperm cells must be able to fertilize a woman's egg. This is not easy, considering the vagina is an acidic environment and unfortunately is quite deadly for sperm cells. Vaginal acidity itself is actually a woman's body defense from bacterial and viral attacks. 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 released, only one is needed to fertilize the egg. So, there was competition between the ages. The speed of sperm is very influential on the resistance of sperm in the vaginal environment which is quite acidic and capable of killing sperm.
The success of one sperm fertilizing an egg will create a fetus later. Too much or accumulation of sperm cells in one egg (polyspermy) can cause extra chromosomes that endanger the sex determination of the fetus, so that the fetus eventually miscarries.
So in short, the more sperm cells are released, the greater the chance of fertilizing the egg. Imagine if only one sperm cell was released in one ejaculation. This can hinder the survival of humanity because of the difficulty of reproduction.
