Abstract
Objective To study the relationship between sperm activity and the level of L-carnitine in seminal plasma of patients with idiopathic asthenospermia by HPLC.Methods Experimental group:idiopathic asthenospermia 50 cases,and the control group:male with pregnancy history 10 cases.The semen parameters (volume,sperm density,viability,motility),and L-carnitine level in seminal plasma were detected with high performance liquid chromatography method.Results There were significant difference between A and B group about sperm density and the percentage of progressive motile spermatozoa,and the level of L-carnitine(P＜0.01).Conclusions The decrease of L-carnitine level in patients with idiopathic asthenospermia,is closely related to the low sperm motility,which shows that L-carnitine can be used to treat idiopathic asthenospermia effectively. Key words: Asthenospermia; Infertility; L-carnitine
