9 More New Facts About Human Sperm

1. The speed of Sperm
Human sperm move with great speed up to 4 mm per minute, the slowest moving speed is 1 mm per minute. In this case, imagine the size of the sperm of only 55 microns in length, in other words it is 0.055 mm.
The average path length in the fallopian tube 175 mm, thus, to overcome this way the sperm takes 44 minutes, but in theory, in practice, it takes 3 days.


2. The probability of conception, only 25%
Even healthy couples practicing unprotected sex have 25% chance of conceiving a child. If you wear tight-fitting pants, instead of the family, your chances are rapidly declining. In most mammals, the body temperature by 3-6 degrees higher than the temperature of the scrotum. Increased scrotal temperature to body temperature leads to a cessation of spermatogenesis during cell division.


3. Sperm are swimming against the stream always

One of the reasons that the path of sperm takes so long because they move against the flow of fluid. Only every 5th sperm move in the right direction after ejaculation.


4. Flight speed
During ejaculation, the sperm of man moves at a speed of 70 km / h.


5. Spoon sperm

Adult male at a time allocates a tablespoon or 2 to 4 ml of semen. For comparison, wild boar sperm allocates one cup or 250 ml.


6. Size does matter

One of the biggest sperm in the world found in rats 170 microns in length. A large number of mammals, including humans, have some of the smallest sperm cells, with only 40 microns in length.

The largest sperm in a tiny fruit fly Drosophila bifurcation, straighten it if the spiral cells of their length, will be equal to 2.5 cm


7. Time to mature

Sperm takes two and a half months to grow, the question arises, where are all the time sperm is.
Storage and maturation of sperm occurs in the epididymis, on average, in each epididymis stores 150 – 200 million sperm. Approximately it takes one week in passing and storage of spermatozoa through the epididymis. In the absence of ejaculations sperm it accumulate in the tail of the epididymis, where they can remain viable for several weeks. “old” sperm undergo a process of destruction – phagocytosis.


8. Sperm – the source of nutrients

From the total seminal fluid, only 5% of the volume occupied by the sperm, the rest – a combination of nutrients and protective substances, which are designed to maintain the cells on the way to the egg.


9. Health food

How to improve the quality of sperm – eating fresh fruits and vegetables, avoid junk food and , take vitamins, refrain from smoking and alcohol. Also,sperm will be more active.
