Abstract
Infertility has been defined as the disability to fulfill pregnancy after twelve months of regular sex coition, with no contraceptive taken. Male factor infertility was explained in terms of low spermatozoa concentration (oligozoospermia), or morphology (teratozoospermia), impaired motility (asthenozoospermia), or in some cases, total lack of spermatozoa in the ejaculate (azoospermia). In several cases, a collection of one, or more of these sperm variables defects may be noticed, evaluation these factors by the initial and most important step is seminal analysis. Our study aims to study some sperm characteristics in asthenozoospermia men in comparison with normozoospermia men before and after glass wool and Sephadex activation. This study involved 60 semen samples collected from male patients that came to male infertility clinic at Al-Nahrain University; the recruited semen samples were divided into 2 groups, (40 asthenozoospermic and 20 normozoospermic subjects). After collected semen samples, and assessed analysis of seminal fluid. Each semen samples were divided into 3 aliquots. The first aliquot prepared was In-Vitro to assessed sperm characterization before activation, the second part using glass wool filtration (GWF) technique, while the last part was prepared using Sephadex. Both techniques resulted equally in reducing sperm concentration, were equally effective in upgrading sperm motility and in minimizing round cell count; however, Sephadex was superior to glass wool method in upgrading the percentage of morphologically normal sperm. Both Sephadex and glass wool techniques has been proved effective to improve semen quality.
