摘要：

Preliminary evidence has suggested that the phosphodiesterase inhibitor pentoxifylline augments the fertilizing potential of asthenozoospermic sperm samples, presumably by improving sperm movement. Here, we used computer-assisted sperm movement analysis to compare the effects of pentoxifylline in normozoospermic and asthenozoospermic specimens. The study focused on the following issues: the changes in individual movement characteristics in response to pentoxifylline, the rapidity of the response, the effect of sperm capacitation on the response, the persistence of the response after drug removal and the variability of responses among asthenozoospermic individuals. Data obtained show that (i) pentoxifylline increases the curvilinear velocity, path velocity, straight-line velocity, lateral head displacement, beat cross frequency and sperm hyperactivation in both normozoospermic and asthenozoospermic specimens, (ii) pentoxifylline does not modify the percentage of motile spermatozoa, (iii) the pentoxifylline effect reaches a maximum within 10 min of treatment in fresh semen as well as in capacitated sperm suspensions and persists for at least 2 h after drug removal and (iv) pentoxifylline improves the movement characteristics in most asthenozoospermic individuals. Results are discussed with regard to methods of therapeutic application of pentoxifylline as an enhancer of sperm movement in assisted reproductive technology.
