Among them, the female factor is about 50%, the pure male factor is about 30%, and the male and female factors are about 20%. Clinically, male infertility is divided into two types: sexual dysfunction and normal sexual function. The latter can be further divided into azoospermia, oligospermia, asthenospermia, spermatozoa, and normal sperm count according to semen analysis results. . In recent years, with the increase of people's understanding of human reproductive problems and the rapid development of andrology research, the rate of male infertility detection has gradually increased, which has drawn great attention from male scientists.
