7 widely believed facts about sperm, which are actually wrong.

The common tale says that millions of people between 20 and 300 million, in order to be precise, heroic sperm swims in competition with each other to reach the egg.

No.

First of all, sperm cells really don't swim straight for most of them. The ability of sperm movement, known as mobility, is often classified as one of the three groups - progressive mobility, non - progressive and rigid mobility.

More than a straight path, the sperm path is a “path with challenging military barriers” and it needs to help female reproductive organs to make sure they reach the finish line. In fact, most of the movement's work is done by the cervical muscles that direct sperm along the phallopian tubes toward the egg.

2. The thickest sperm is the most fertile

This usually means that there is a high concentration of sperm or a high number of irregular - shaped sperms.

3. Spermatoids live only for a short time 

Not always! Life expectancy depends on where sperm “zbarkon” after the spill. In a cold, dry place, sperm can rarely last up to 30 minutes.

4. Spermatoids stay fertile and healthy for the rest of a man's life

Spermatoseoids, or sperm, are developed indefinitely, but the quality and mobility of sperms declines with age.

5. Every sperm is healthy

Most sperm cells never get to the egg for a number of reasons. To be considered fertile, even 100% spermoids should not be moved as long as 40% are mobile, we're dealing with a fertility man. And of those 40%, not all get to the egg.

6. Para-spemas cannot cause pregnancy

Wrong! Biologically, pre-reservation should not contain spermoside, but the remaining sperms in the bridge, the tube through which urine and sperm are extracted, can be mixed. So, even if you remove your penis during the exfil, there's a little, small chance, that some sperm will cause pregnancy.

7. Ananas makes sperm taste amazing

The aroma and flavor of sperm, such as that of many body fluids, are affected by general genetics, diets, and life - styles. As everyone's spirit smells, the sperm of each one has its own unique fragrance.
