Etiology 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 کاملthe effect of varicocelectomy on sperm parameters, membrane integrity and sperm chromatin condensation
introduction: varicocele is considered as a common cause of male infertility. the aim of this study was to evaluate the effects of varicocelectomy on sperm parameters, sperm membrane integrity and sperm nuclear maturity. materials and methods: in this study along with routine semen analysis, hypo-osmotic swelling test (host), and aniline blue staining for assessment of as 45 and 90 days after i...
متن کاملEffect of chromatin condensation on frozen-thawed sperm DNA integrity in normozoospermic men
Background and Aim: Sperm cryopreservation is a common technique used for management of male infertility. But this method has detrimental effects on sperm DNA and chromatin quality. Evaluation of different markers associated with the health of genetic material of sperm is beneficial for determination of the fertility of sperm. The aim of this study was to assess the effect of sperm chromatin co...
متن کاملP-75: The Protective Effect of Vitamin C on Sperm Parameters and Chromatin Condensation in Diabetic Mice
Background: Diabetes mellitus (DM), primary or idiopathic, is a chronic disorder of the carbohydrate, lipid and protein metabolism, characterized through hyperglycemia and glycosuria. DM can involve male reproductive function at many levels. Vitamin C ( ascorbic acid) is one of necessary elements in human and mammalian diet that is very important in fertility. Vitamin C prevent from gamets dama...
متن کاملSperm competition influences sperm size in mammals.
Among mammals sperm competition leads to selection for increased sperm numbers but it is not known whether it also leads to changes in sperm size. Two contrasting theoretical predictions have been made. The first hypothesis relies on the assumption that there is a trade-off between sperm numbers and sperm size and predicts that, in species confronting sperm competition, there will be a concomit...
