Abstract
Catsper 1 is an important protein involved in calcium channel synthesis. These channels are essential for the hyperactivity of sperm flagellum, chemotaxis towards the egg, capacitation and acrosome reaction. Data analysis from unexplained infertility (n=50), idiopathic infertile men (Asthenozoospermia (n=50), Oligozoospermia (n=50)), and Normospermia fertile men as a control (n=26). The expression of CatSper1 protein expression in spermatozoa was reduced in unexplained infertility (mean± SD. Error 64.32±2.5 and in Asthenozoospermia 46.6±2.1and Oligozoospermia 53.86±4.1 while significant increase was observed in Normospermia fertile men 115.19±2.3. CatSper1 protein expressions was shown to have a positive correlation between sperm concentration, Sperm Progressive motility percentage and sperm normal morphology present in idiopathic infertile men respectively (r= 0.822, r = 0.651 and r = 0.742). A positive correlation was found between CatSper1 protein expression and sperm concentration, Sperm Progressive motility percentage and sperm normal morphology present in unexplained infertile men Respectively (r=0.845, r = 0.576 and r = 0.582). The present study shows the importance of protein catsper 1 in infertile men and its positive correlation with sperm parameters.
