The process of sperm production and basic knowledge of semen

After the testes produce sperm, the sperm need to mature in the epididymis and are mainly stored in the "storage chamber".

The sperm are stored in the epididymis and seminal vesicles. During ejaculation, the sperm travel along the "highway"-the vas deferens.

The tube was forced into the woman's uterus.

Although there are many details in the process that we are still unclear about, it is undeniable that sperm production requires...

Many internal and external conditions are required: First, the male's testicular structure must be normal and capable of...

First, it provides a complete production line for sperm production; second, it needs to be around puberty, under the influence of hormones...

The male testicles can only produce sperm under certain conditions; thirdly, the male testicles need to have a good environment.

The working and living environment, including its blood supply, nutritional and hormonal support, and suitable temperature, are all important factors.

Finally, of course, all the ducts within the testicles must be unobstructed.

After sperm are produced in the testes, they are transported to the epididymis. In the epididymis, sperm acquire two...

These two abilities are motor ability and the ability to combine with an egg cell for fertilization. For example...

If sperm is extracted directly from the testicles, it is inactive, or rather, immature.

It must further absorb nutrients and energy within the epididymis and undergo further transformation before it can function.

Movement. On the other hand, during the slow journey of sperm from the head, body, to the tail of the epididymis.

It gradually matured, discarding some less useful structures and components, and thus achieved...

The degree to which an egg can be fertilized.

Generally, the entire process takes about 90 days, during which time the sperm is extracted from the testicles.

The time from blastocyst formation to sperm formation is approximately 72 days, and sperm remain in the epididymis for about two weeks after entering the epididymis.

It is then primarily stored in the epididymis and seminal vesicles. During ejaculation, it is released along with other fluids in the semen.

The components are excreted from the body and fertilization occurs within the female body. Therefore, from the initial production to maturity, sperm...

From ripening to transport and excretion, it is a rather complex, delicate, and subtle process.

Clearly, any abnormality in any stage of sperm production can lead to fertility problems.

In the process of spermatogonium production, if genetic abnormalities cause damage to the cells...

If cell division malfunctions, spermatogenic cells will arrest at a certain stage, or stop at the spermatogenic stage.

The germ cells, or those arrested at the spermatogonium stage, no longer divide further. Furthermore, due to the testes...

If there is insufficient hormones or nutrients in the testicles, sperm may die prematurely.

If there is a problem with the epididymis, sperm cannot move or mature within it.

If the seminal vesicles or prostate cannot acquire the ability to fertilize, the woman cannot conceive naturally;

Inflammation of the vas deferens can also interfere with sperm motility; if the vas deferens is blocked, sperm will also be unable to move.

The sperm can successfully reach the woman's body. Therefore, in the entire process of sperm formation, at any point...

Any problems that arise can affect fertility.

What is semen?

Normal semen is a viscous liquid mixture composed of sperm and seminal plasma. Sperm consists of...

The testes develop and mature within the epididymis, and the semen is transported out through the epididymal duct, vas deferens, and other vas deferens ducts.

Serum is mainly a mixture of secretions from accessory glands such as the prostate, seminal vesicles, and bulbourethral glands, and also contains...

Small amounts of testicular fluid and epididymal fluid are present. Normally, sperm and seminal plasma remain in their respective positions during ejaculation.

During the process, sperm and seminal plasma mix to form semen.

Sperm make up about 5% of semen, with the remainder being seminal plasma. Seminal plasma contains a large amount of water and fruit extracts.

In addition to sugars, proteins, and polypeptides, it also contains various other sugars (such as glucose) and enzymes (such as those mentioned above).

Seminal plasma contains prostaglandins, inorganic salts, and small organic molecules, components similar to those found in blood plasma.

The carbohydrates (mainly fructose) and proteins in sperm provide energy and nutrients. In terms of volume...

In fact, 90% of seminal plasma comes from secretions of accessory glands, mainly the prostate gland and spermatorrhea.

Cyst glands, a small portion of which originate from bulbourethral glands and epididymis.

Due to Neisseria gonorrhoeae, HIV, Mycoplasma, Chlamydia, Trichomonas vaginalis, and hepatitis.

Many pathogens, including toxins, can exist in semen, so semen can transmit these pathogens, leading to...

Corresponding diseases. At the same time, dozens of microorganisms can be detected in semen, some of which are pathogenic microorganisms.

This substance can cause reproductive tract infections in women.

How is male infertility classified?

"Primary infertility, secondary infertility, organic infertility, functional infertility-what are these?"

"What does it mean?" Many patients are confused when they see or hear these terms. They want to ask the doctor.

There are too many patients, and the doctor can't explain everything in detail. Actually, infertility can be viewed from different perspectives...

Therefore, there are different classifications. For example, based on the history of infertility, it can be divided into primary infertility and secondary infertility.

Infertility can be classified as absolute or relative based on the likelihood of treatment outcome; it can also be classified based on etiology.

Infertility can be categorized into organic infertility and functional infertility. There are also congenital infertility and acquired infertility.

Classification of infertility, etc. Here we will mainly talk about primary infertility and secondary infertility.

Primary infertility refers to a man's infertility as a condition in which he has never fathered a child with a woman, regardless of whether the woman is a fertile or male.

His wife was also his sexual partner. Secondary infertility, on the other hand, occurs when a man has previously impregnated a woman.

Regardless of whether this woman is his current spouse, and regardless of whether the child is born after conception,

However, despite having had unprotected sex for the past 12 months, the woman has not become pregnant.

In reality, the diagnosis is based on the patient's reproductive history. Generally speaking, secondary infertility has a relatively high incidence rate.

The chances of restoring fertility are high. Therefore, distinguishing between primary and secondary infertility is important.

Clinically significant.
