Oligospermia
（重定向自Oligozoospermia）
Oligozoospermia, refers to semen with a low concentration of sperm and is a common finding in male infertility. Often semen with a decreased sperm concentration may also show significant abnormalities in sperm morphology and motility (technically "oligoasthenoteratozoospermia"). There has been interest in replacing the descriptive terms used in semen analysis with more quantitative information.
