Incidence of sperm-tail tyrosine phosphorylation and hyperactivated motility in normozoospermic and asthenozoospermic human sperm samples.
Our objective was to study the incidence of sperm-tail phosphotyrosine immunoreactivity in normozoospermic and asthenozoospermic human sperm samples, its association with sperm motion parameters, particularly hyperactivated motility, and its potential involvement in the pathogenesis of asthenozoospermia. The work was conducted as a prospective experimental study in the Sperm Biology and Androlo...
متن کاملimpact of sperm cryopreservation on semen parameters in asthenozoospermic men
background: human sperm cryopreservation has proven to be very valuable. cryopreservation has effects on function, morphology and percentage of fertilization capacity of human sperm. also, it has been revealed that cryopreservation has a role in sperm dna fragmentation and infertility. in this study, viability, motility, dna fragmentation and for the first time, intracellular nitric oxide asses...
متن کاملApplication of Vitality Tests on Asthenozoospermic Semen from Infertile Men
Fresh semen obtained from infertile men occasionally exhibits the total absence of motile sperm (100%asthenozoospermia). Vitality tests may reveal that a proportion of the immotile sperm has functional membranes, which are considered viable. An easy test for the prior determination of sperm viability may assist in sperm selection for the microinjection of oocytes. The main objective of this stu...
متن کاملEffect of nerve growth factor on sperm quality in asthenozoosprmic men during cryopreservation.
BACKGROUND Although routinely used in assisted reproductive technology, human sperm cryopreservation is not an entirely successful procedure. This study determined the effect of nerve growth factor (NGF) supplementation of cryopreservation medium on post-thaw viability, motility, intracellular nitric oxide (NO) concentration, and DNA fragmentation of human spermatozoa in asthenozoospermic men. ...
متن کاملSignificant Correlation between High-Risk HPV DNA in Semen and Impairment of Sperm Quality in Infertile Men
Objective Background: Human papillomavirus (HPV) is a DNA virus that causes sexually transmitted infection (STI). Recent reports have suggested that HPV may affect sperm parameters and lead to male infertility. This study is aimed to evaluate the correlation between seminal high-risk HPV infection and impairment of sperm quality in Iranian infertile men. MaterialsAndMethods Materials and Method...
