Varicocelectomy: semen parameters and protamine deficiency

effect of varicocelectomy on semen parameters and protamine deficiency 3 and 6 months post surgery

different methods have been used to evaluate the beneficial effect of varicocelectomy; these include semen parameters and pregnancy rate. due to high biological variability of semen parameters, sperm functional tests have been considered as an efficient end point in assessment of fertility. therefore, the aim of this study was to evaluate the effect of varicocelectomy on semen parameters and sp...

Semen Parameters and Chromatin Packaging in Microsurgical Varicocelectomy Patients

Semen Parameters and Chromatin Packaging in Microsurgical Varicocelectomy Patients

BACKGROUND Varicocelectomy is considered as standard treatment for male infertility for clinical varicocele. The aim of this study is to address the effects of varicocelectomy on semen parameters, chromatin packaging, and pregnancy outcome. MATERIALS AND METHODS This retrospective study was carried out between June 2006 and February 2011 on 145 infertile men with grade II or III varicocele. M...

Sperm parameters, protamine deficiency, and apoptosis in total globozoospermia

BACKGROUND Globozoospermia is a severe form of teratozoospermia (incidence < 0.1%) in infertile men that is characterized by round headed sperm and acrosomeless in semen. OBJECTIVE To compare the semen parameters, protamine deficiency, and apoptosis in ejaculated spermatozoa between globozoospermic and normozoospermic men. MATERIALS AND METHODS Thirty six semen samples were divided into two...
