Abstract

Background: From each six couples, one is affected by infertility and half of these cases traced back to male. Sperm cryopreservation is a useful domain of Assisted Reproductive Technologies (ART's) used to preserve men fertility but unfortunately may be consequence of cryoinjury. Theophylline is an activating substance using to enhance and prolong fresh and thawed sperm motion by increasing a source of energy. Objective: This study was designed to evaluate whether in vitro sperm activation by Theophylline solution before cryopreservation improves percentages of sperm parameters post freezing-thawing process as compared with activation if done by the same substance but after cryopreservation. Subjects, Materials and Methods: Sixty male were participated in this study, twenty normozoospermic male and forty asthenozoospermic male. Semen samples were collected and seminal fluid analysis was done according to (WHO 1999, 2010). Each sample was divided into two aliquots, one of which was equally divided into two groups, the centrifugation was done to remove seminal plasma and then Swim-up technique was dependent for in vitro sperm activation by using FertiCult medium and Theophylline solution respectively prior to cryopreservation and one of which was also divided and activated by the same materials but post cryopreservation. Sperm parameters were measured in each activated group according to (WHO 1999). Results: using of FertiCult Flushing medium and Theophylline solution to activate fresh semen resulted in significant reduction in sperm concentration and also resulted in highly significant improvement (P
