The quantity, motility, and shape of the sperm determine the quality of the seed. Impaired semen qualities often involve a combination of these three factors.
A man with few sperms that little mobile, makes a smaller chance of achieving fertilization than someone with a little good but motile. Most men with optimal seed there is a combination of low, low motility and many different types of cells.
Even with reduced sperm quality, a pregnancy occurs, although less likely than whether it takes longer. The seed of reduced quality shows no increased risk of malformations in an infant.
The number of cells is an initial factor. Normally, on a 100 until and 200 million cells, Fri Per milliliter is that 20 to 50 million. In less than 20 million sperm per milliliter is called oligo-zoosperm (few cells).
