You are viewing: What is Sperm?

Sperm is a fluid secreted from the penis of a man. To fertilize, they must swim through the cervix, then through the uterus to reach the fallopian tubes and ovaries of the woman. How fast is sperm motility? How long do sperm live? The answer will surprise you.

Most sperm don’t actually swim straight. Usually, common, normal, Sperm movement speed classified into one of the following three groups:

Actively moves in a straight line or large circle.Moves in all patterns but does not move forward .Move – no movement.

The speed of sperm movement is described as an obstacle race and requires a successful finish. In fact, most of the advocacy work of sperm It is carried out by the muscles of the uterus, which attract sperm along the fallopian tubes towards the egg.

Sperm Thicker does not necessarily mean stronger sperm. Usually, there is a high concentration or a large number of abnormally shaped sperm, so they still need help from the female reproductive system to stay safe.

When sperm enter the vagina, they come into contact with cervical mucus. This mucus does two things: Protect and deny. It protects sperm from the acidity of the vagina as well as eliminates sperm with shape and motility that cannot reach an egg.

The lifespan of sperm also depends on where the sperm “landed” after ejaculation. After being ejaculated into the vagina, sperm can live up to five days. This is due to the protective effect of cervical mucus.

But if the sperm dries out, they die. Ejaculated sperm that fall on dry, cold objects can die after a few minutes, although very rarely they can last up to 30 minutes. They can even die faster in a hot tub or from heat or chemicals in the water.

It is quite a long journey for the sperm to reach the egg. During intercourse, when the sperm leaves penis, they will not go directly to the uterus. Some sperm will be attached to epithelial cells in the fallopian tubes or stored in tiny chambers called “crypts” until primordial fertilization – “ovulation”.

5. Sperm always proliferate and stay healthy for life

One of the long-standing myths has been that while a woman’s eggs are limited, sperm is always produced throughout a man’s life.

It is true that sperm production, or spermatogenesis goes on indefinitely, but sperm quality and motility decline with age.

According to an Icelandic study, How long do sperm live? depends on the age and genes of the man. Older men are also more likely to pass the gene mutation on to their children, about four times faster than women.

Also according to a 2017 study, it was found that about 1.4 million people in Sweden have a consistent linear relationship between a man’s age and the likelihood that their children will be born with a mutation. genetic variation that neither parent has.

Wearing tight panties reduces sperm count, while loose panties help keep everything at the right temperature for sperm production. But actually, underwear has almost no effect on your sperm.

A 2016 study found little difference in sperm count based on underwear choice. But another 2018 study made science waves when it found that men who wore loose panties had 17% more sperm than men who wore tight panties. However, the 2018 study authors cautioned that their results did not take into account other factors that affect sperm production, such as the type of pants or fabric. Ideally, wear what makes you comfortable.

Most sperm cannot penetrate an egg for a number of reasons. To be fertile, even 100% of sperm don’t need to move, as long as 40% can move then you should be fertile. And in that 40%, not all sperm can get into the egg.

Sperm movement speed and the shape of the sperm is also an important part of the success of their journey to their destination. Having multiple heads, tails, odd shapes, or missing parts can cause unsuitable sperm to be discarded. And even healthy sperm cannot pass this “contest”. Sperm can travel through the fallopian tubes and lodge in a woman’s fluid reservoir around her internal organs. Yes, sperm can float in the body, but cannot fertilize.

This is wrong. Biologically speaking, pre-cum does not contain sperm – but sperm remains in the urethra, through the tube, both urine and semen are expelled, possibly mixing. into each other. A 2011 study found that nearly 37% of pre-cum fluid samples collected from 27 different subjects contained significant amounts of healthy, motile sperm. And a 2016 study found 42 men had at least 17% of pre-cum samples filled with viable sperm. So even if you use external ejaculation, some sperm still have a chance to get into the vagina and cause pregnancy.

9. More sperm will easily conceive successfully

This is quite the opposite. A large sperm count in a single ejaculate is good, but it still has a disadvantage. The higher the sperm concentration, the greater the chance that the sperm can fertilize an egg.

Normally, only one sperm cell is allowed to fertilize an egg cell, resulting in the development of an embryo. After the first sperm breaks down a layer of protein around the egg, this layer stops other sperm from getting through. But in the rare case of too many sperm reaching the egg (two – or more), they can break through this layer and eventually fertilize the egg. This is called polyspermy.

By adding genetic element to the egg, this has increased the risk of DNA mutations, brain conditions such as Down syndrome or potentially fatal defects of the heart, spine and skull. .

Keep this in mind if you and your husband decide to use in vitro fertilization (IVF) to get pregnant. Because IVF By bypassing many reproductive functions that limit the number of sperm that can get into an egg, your semen doesn’t need to have millions of sperm in it to reproduce.

This is an unscientific thought. You have to digest more than 100 times the amount of sperm in order to see any nutritional benefits from it.

Although it is true that semen consists of components such as vitamin C, zinc, protein compounds, cholesterol and sodium, but claiming that sperm contributes to your daily nutritional value is false advertising. Plus, some people actually have an allergic reaction to semen, so you shouldn’t eat it.

It is said that pineapple is good for the taste of semen, but this argument is not actually supported by any scientific evidence.

The first thing to learn here is that the smell and taste of semen, like many of your bodily fluids, is influenced by overall genetics, diet, and lifestyle. Just like the smell of breath, the smell of semen also has a different taste in each person.

The next thing is that no food or liquid can significantly change the scent of semen. Following a diet rich in nutrients like vitamins C and B-12 can have a positive effect on sperm count, their morphology, and their ability to function.
