Shot of sperm when ejaculation Exceed 40 km/hour

During orgasm, men experience genital contractions are strong enough to be able to eject sperm with speed 48 km / hr. But once into the vagina, the sperm takes 3 days to reach the egg a distance of only 15 cm.

The strong blast of sperm during ejaculation is triggered by the contraction of muscles around the vas deferens or sperm channel. Shortly before orgasm, the sperm collected in the vicinity of first base of the penis, so that when the time comes, the thick white liquid would be sprayed with a high speed.

Dr. Trina Read, konsultas sex of the Society for the Scientific Study of Sexuality (SSSS) said the blast of sperm had an average speed of 48 km / h and sometimes even reaches 69.2 km / hr. This far exceeds the speed limit safely drive in the city that is 40 km / hr.

Strength bursts of sperm in the ejaculate can be weakened due to various factors including the distance of time with the previous ejaculation. The longer given the lag, the optimal power semburannya. Of course, the quality of stimulation and health conditions affecting male genitalia participate.

"After ejaculation, the penis will experience muscle relaxation so that its size decreases. Need lag time called the refractory period to get an erection again, the length varies in every man," says Dr Read as quoted from its website, TrinaRead, Monday (07/03/2011 .)

Although spraying with high strength, but slows the rate of sperm immediately upon entering the vagina. To pass through the cervix or neck of the womb a distance of less than 5 cm, the sperm takes about 5 minutes and even took 72 hours to reach the egg a distance of only 15 cm.

Men who semburannya below the average speed is also no need to be discouraged, because it did not affect the ability to fertilize their partner. Male fertility is determined by the motility or the ability of each sperm cell to keep swimming toward the egg.
