How does the motion of sperm work?

The mobility of sperm is an important function of gestation, usually divided into three categories by type of activity: 1. Forward motion sperm: This refers to sperm that can move forward quickly and move towards the ovaries, a type of sperm that has the chance to successfully gestation. 2. Non-directive motion sperm: is a sperm that, although removable, usually moves in situ or has only a small amount of small motion, and which cannot be conceived. 3. Non-movement sperm: This means that sperm is completely inert and has no ability to move, and the vast majority is dead sperm, which is equally impregnable. Infertility. Infertility.
