ABSTRACT
The objective of this study was to explore the influencing factors of asthenospermia. Electronic medical record and semen samples were collected from 201 male patients in The Fourth People’s Hospital of Taizhou from November 2021 to March 2023. Multivariate logistic regression model was used to analyze the risk factors of asthenospermia after adjusting all covariables. Linear regression model was conducted to analyze risk factors for the three main indicators of asthenospermia. Men with asthenospermia have higher rates of sperm malformation and sperm DNA fragmentation (97.2% versus 95.1%; 31.4% versus 17.9%). Computer usage, sperm malformation rate and smoking were risk factors for asthenospermia, the adjusted ORs were 1.87, 3.97 and 1.40, respectively. The protective factor of sperm motility, sperm forward motility rate and sperm non-forward motility was exercise. It was concluded that lifestyle factors (computer usage hours, smoking and alcohol consumption), sperm malformation rate and sperm fragmentation rate significantly affected asthenospermia, however exercise reduces the risk of asthenospermia.
