Will you get pregnant?

When out of the man's body, semen could spurtwith a speed of 40 km / h. But once reaching the eggs, a process or approach pedekate could take3-5 days for sperm movement so slow 0.3 cm /hour.

Speed ​​of sperm in the female reproductive organswas not always constant, it depends on the qualityand environmental conditions around. One of the most influential indicator of quality is the long tail, the longer it is usually faster.

However, if the average is taken, then the journeyof sperm to penetrate cervical cells or cervicallength is only 5 cm could take many hours. Even to reach the ultimate goal which is to meet the eggcell which is only 15 cm, the sperm takes 3-5 daysbecause of its speed is only 0.3 cm / hour.

Speeds as low as it may sound slow for humans,but has actually been speeding considering thesize of the sperm is on average only 42.3micrometers. Do not compare it to the man whocan drive 6-8 km / h only a small run, because the size is much smaller.

Because sperm movement is so slow to humansize, it is likely already pregnant when having sexwithout a safety net may still be prevented. Sometypes of emergency contraception works by exploiting the pedekate between sperm and egg cells are so slow.

Emergency contraception is also called theMorning After Pill (MAP) or Plan B works by manipulating the hormonal conditions. Quotedfrom Menshealth.com, Tuesday (01/17/2012),changes in hormonal conditions make travel moreinhibited sperm and the egg can only be met afterinfertility.

The use of emergency contraception is usually still very effective in preventing pregnancy up to 2-3 x24 hours, and even then if the sperm is moving faster than average. If the average speed is taken,then emergency contraception is effective up to 120 hours or 5 days after sex.
