P-50: Evaluation of Sperm Parameters and Chromatin Abnormalities in Infertility with CASA and Chromatin Dispersion Test
Background: Although sperm selection according to morphologic and motility characteristic, made to some what the fertility successful, but sperm’s normal morphology cannot demonstrate sperm DNA competence. Since the health of sperm DNA is affecting the results of assisted reproductive technology; the aim of this study is to evaluate semen parameters measured by CASA with sperm chromatin abnorma...
متن کاملP-117: Methamphetamine Can Induce Sperm Chromatin Abnormality and Apoptosis in Mice
Background: It is showed that methamphetamine has harmful effects on male reproductive system. The aim of this study was to investigate the effects of methamphetamine administration on testis weight, sperm count, sperm morphology, and chromatin status as well as sperm apoptotis followed by the cytochemical tests in a mouse model. Materials and Methods: Twenty four NMRI male mice were divided in...
متن کاملP-61: Effects of Acrylamid on Sperm Parameters and Chromatin Quality in Mice
Background: Acrylamid (AA) is found in carbohydraterich foods that are prepared at high temperatures, such as French fries and potato chips. The toxic effects of AA in male animals include degeneration of epithelial cells of seminiferous tubules, decreased number of sperm and elevation in abnormal spermatozoa. The aim of this study was to evaluate the detrimental effects of AA on sperm paramete...
متن کاملEtiology and Evaluation of Sperm Chromatin Anomalies
Evidence suggests that human sperm chromatin anomalies adversely affect reproductive outcomes and infertile men possess substantially amount of sperm with chromatin anomalies than fertile men. Routine semen analysis evaluates parameters such as sperm motility and morphology, but does not examine the nuclear DNA integrity of spermatozoa. It has been suggested that altered nuclear chromatin struc...
متن کاملP-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...
