Over 15 million sperm per milliliter is considered normal, according to the WHO in 2010. Older definitions state 20 million. A lower sperm count is considered oligozoospermia. A vasectomy is considered successful if the sample is azoospermic (zero sperm of any kind found). Some define success as when rare/occasional non-motile sperm are observed (fewer than 100,000 per millilitre). Others advocate obtaining a second semen analysis to verify the counts are not increasing (as can happen with re-canalization) and others still may perform a repeat vasectomy for this situation.

It moves to a square that is two squares away horizontally and one square vertically, or two squares vertically and one square horizontally. The complete move therefore looks like the letter ``L''. Unlike all other standard chess pieces, the knight can ``jump over'' all other pieces (of either color) to its destination square. It captures an enemy piece by replacing it on its square. The knight's ability to ``jump over'' other pieces means it tends to be at its most powerful in closed positions , in contrast to a bishop. The knight moves alternately to light and dark squares.
