Is it better to have concentrated sperm or diluted sperm?

A man's body produces sperm and discharges it during sexual intercourse. This goes through a series of complex processes. As we all know, under normal circumstances, a man's semen is white or light yellow. Each ejaculation contains a large number of sperm. In addition, you will also find that sometimes the ejaculated sperm is thicker and sometimes it is thinner. So which type of sperm has better quality?

Is it better to have concentrated sperm or diluted sperm?

For men, normal semen is neither thin nor thick. Semen that is too thick or too thin will have an impact on fertility and will directly affect the motility and activity rate of sperm.

1. Semen is too concentrated

Before ejaculation, semen is stored in the body in liquid form. When semen is ejaculated from the penis, it immediately turns into a milky white or slightly yellow translucent jelly under the action of a protein-like substance secreted by the seminal vesicles. This is the nature of semen that people usually see.

At this time, the sperm is "solidified" in the semen and cannot swim freely. After 5 to 30 minutes, with the participation of a hydrolase secreted by the prostate, the semen begins to liquefy, gradually changing from a jelly-like state to a thin watery state.

It is liquid at the beginning to facilitate the ejaculation of semen. It forms a gel immediately after ejaculation, which helps the semen stay in the vagina for a sufficient period of time so that the sperm can get sufficient rest and energy. Once liquefied, the sperm has enough energy to swim quickly and head straight for the egg for a blind date.

If the prostate or seminal vesicles become inflamed, due to the lack or destruction of the secretion of hydrolytic enzymes, the semen of these patients may not liquefy or liquefy incompletely for a long time after ejaculation. Some may even take half an hour or even an hour to liquefy. This is a pathological phenomenon, medically known as semen liquefaction.

2. Semen is too thin

① Varicocele

When varicocele occurs, the local temperature of the testicles increases and vasoactive substances increase, thus affecting the spermatogenic function of the testicles. However, the degree of varicocele is not proportional to the sperm quality.

② Cryptorchidism

Cryptorchidism is one of the important factors affecting semen quality. About 60% of patients with unilateral cryptorchidism are infertile. Therefore, if the sperm density is low and cryptorchidism exists, early treatment is necessary.

③Urinary tract infection

Chronic infection of the accessory reproductive glands can affect various test indicators in semen, which is more important than whether the semen is thick or thin.

④Autoimmunity

Reproductive immunology studies have found that male autoimmunity can affect fertility, and anti-sperm antibodies can affect sperm production and transport.

⑤ Endocrine abnormalities

Normal male spermatogenesis depends on the normal function of the hypothalamus-pituitary-gonadal axis. Any obstruction in any of these links will cause thin semen.
