Varicocele Time-dependently Affects DNA Integrity of Sperm Cells: Evidence for Lower In vitro Fertilization Rate in Varicocele-positive Rats

BACKGROUND We designed this study to clarify how varicocele can time-dependently affect sperm morphological parameters and DNA integrity. In this study, we intend to estimate the effect of various periods of varicocele on the in vitro fertilization (IVF) rate in rats. MATERIALS AND METHODS In this experimental study, left varicocele were induced as the test group (n=18) which was further sub-...

P-17: Body Mass Index and Sperm Counts Associated with Varicocele in Infertile Men

Background: Varicocele is a progressive disease and etiology of varicocele is not well known. Some studies have been reported that prevalence of varicocele decreases with increasing BMI. The aim of this study was to determine interrelation of varicocoele with height, body mass index (BMI) and sperm counts in infertile men. Materials and Methods: We retrospectively evaluated the data of all pati...

P-5: Assessment of Sperm Chromatin Status in Rat Experimental Varicocele

Background: Varicocele is considered as a common cause of male infertility and can affect spermatogenesis. In addition, it also predisposed sperm to chromatin damage and morphological alternation. Other factors, such as environmental and genetic conditions also predispose sperm to these conditions. To answer this question, we aimed to evaluation of DNA fragmentation and protamine deficiency thr...
