Sperm: what is it, how is it produced and what does ejaculate consist of?
I understand perfectly well that this is a necessary liquid in order to imagine a new life. All men are ejaculation factories. The sperm, that nimble food, is the cause of conception. They are produced in millions, but only the most agile of them participates in fertilization.

Let”s take a closer look at this mysterious liquid.
What is sperm?
Sperm are male cells responsible for fertility. According to scientific theory, it is a gametophyte. Gametha is half of the whole and speaks a simple language. To obtain the final result, i. e. human embryo, a second gamete is needed — a female egg. When the sperm and egg are found, conception occurs.
Well, now let’s arm ourselves with a microscope and look at the sperm. There are three parts.
Very important components. The head is the breast in which chromatin is stored. Chromatin is made up of DNA and proteins and is a component of chromosomes. Humans have 46 chromosomes. However, it is a complete package. However, a sperm contains 23 chromosomes, and an egg contains 23. 23 + 23 = 46, “a little man comes out.”
This is the membrane that surrounds the head of the sperm. It consists of proteins that help dissolve the egg shell.
- Centromere or centromere.
It produces mitochondria. Mitochondria are responsible for sperm motility.
Life wouldn”t be the same without a tail. No tail — no movement. It is in this area that sperm reach their goal and fertilize the egg. The tail creates a wave-like movement, like a snake in water, due to the fact that Zhivchik moves forward through the woman”s body.
Where is sperm produced
Sperm are produced in the palps, or spermatic circle. In addition, the testicles produce testosterone. This is the hormone that makes a man a man. Women also have it, but it has different tasks.
The process of producing ejaculate is called spermatogenesis. It all starts with a mental flagellum or tubercle. Spermatozoa, future spermatozoa, are born in them.
Before a sperm becomes a sperm, it goes through several stages. It takes time for sperm to mature. On average, it takes about 2. 5 months for a sperm to mature and become a full-fledged sperm. Since this process is always ongoing, fertilization is possible every day without the person”s knowledge.
How long does a sperm live?
One ml of semen from a healthy man contains approximately 100 million sperm. Sperm are extremely tenacious. Entering a woman”s body. They can spend up to five days incubating the eggs. This makes calendar methods of contraception less effective. Surprises often happen.
Sperm count and motility
Healthy sperm is determined by two parameters. The number of sperm in 1 ml of ejaculate and their mobility. The more “feedings”, the faster and denser they are, the higher the likelihood of conception.
Sperm
The male sperm production plant operates 24 hours a day. There is no exact amount of daily sperm production. Everything is very individual and depends on many factors. By the way, the size of the test circle is far from an indicator. You can have bluebells and at the same time bear fruit, or conversely, have a tix sparrow the size of a round “coconut” but at the same time breed like rabbits.

The chemical composition of male sperm is very interesting from a scientific point of view. They say it can be useful too. This is true? Myths and truth Before.
There are interesting studies showing that sperm count is directly related to a man”s ethnicity. For example:
- Hispanics: 231-398 million sperm per day.
- White: 193-318 million sperm per day.
- Chinese: 70-173 million sperm per day.
When couples face infertility problems, men are not left behind. The dark times are over and 50% of infertile couples can now empathize with men. Many factors: ecology, nutrition, lifestyle. Direct effect on sperm quality and male fertility.
Sperm analysis is very simple. Through masturbation, sperm is collected in sterile containers and sent to a laboratory for semen analysis. First of all, it is assessed:
First ejaculate
- Appearance of spermatozoa: presence of all details.
- Mobility. After all, you can look great on the outside but still be completely immobile.
- Ejaculate volume. Therefore, it is recommended to abstain for several days before testing.
- Number of sperm in 1 ml.
Men report infertility if their sperm count is below average. In addition, men may suffer from azoospermia. This is the complete absence of sperm in semen. There are many possible causes, and your doctor will look at them.
Sperm motility
The egg is a lazy young woman who is unable to move. It moves into the uterus using cilia in the fallopian tubes. What can you do, lady? All hope lies in the army of rabid sperm attacking the uterus.
A 2015 study found that 85% of infertile men produce low-quality sperm. This manifests itself in a decrease in sperm motility.
It is important to understand that with age, sperm quality decreases, sperm motility is lost and their morphology is often disrupted. Therefore, even if after 40 years paternity has not worked out, there is no need to become particularly hysterical. In addition to medical indications, there are other factors that can seriously affect sperm quality:
- Lack of exercise. Sure, the couch and TV are tempting after a busy day, but low activity levels can make sperm just as lazy as their owners.
- Alcohol. This is a serious enemy. A drunk sperm poses a serious threat to the future embryo. Well, if it doesn”t end up where it was going. Fortunately, nature has dealt with this, and excessive alcohol consumption can get stuck and harm the scout.
- Nicotine. It works the same way as alcohol.
- Drugs. There are no comments here. They do not kill themselves, much less sperm.
- Steroids and workout supplements. Gyms are great. Until men decide to start taking steroids and supplements to build muscle. There is a risk of becoming like a bull from a dead poster, but at the same time completely sterile. Everything should be in moderation.
- Heart pathology. Cardiovascular disease is a common cause of male infertility.
- Overheating Fans of frequent trips to the sauna should be careful. There is a risk of simply “cooking” unsuccessful sperm. No, nothing bad will happen from spending a few hours in the steam room. But a day of continuous swimming combined with a hot bath is an explosive mixture.
Therefore, it is worth reconsidering your lifestyle if you want to have an heir and experience the joy of fatherhood.
Sperm banking
If a man”s sperm factory is running smoothly and delivering a high-quality product, men can earn extra money by becoming sperm donors. IVF, intrauterine insemination or IUD require donor sperm.
In intrauterine insemination, sperm is injected directly into the uterus. IVF means that eggs are fertilized in a test tube and the already growing embryo is inserted into the uterus.
The sperm is collected into a sterile container through masturbation. It is then examined and either used immediately or frozen.
Let us remind you that donor sperm undergoes strict control for infections and genetic diseases. Therefore, you can be sure of high quality sperm for insemination.
