Evaluation method of sperm quality

The invention discloses a sperm quality evaluation method, and belongs to the technical field of biological detection. According to the evaluation method, the proteasome activity in semen is taken as an index, the proteasome activity among different age groups, different sperm motility groups, different DNA fragment groups, different morphological rates and different head malformation rate groups is measured, the proteasome activity among different semen quality index groups is found to have no significant difference, but the higher the sperm proteasome activity expression is, the higher the sperm proteasome activity expression is, the higher the sperm proteasome activity expression is, the higher the sperm proteasome activity is. The fertilization rate and 2PN rate of conventional in-vitro fertilization are higher. Therefore, the sperm proteasome activity of a patient with unknown sterility or low conventional in-vitro fertilization rate can be considered and detected, and a basis is provided for clinically
