Identification of proteomic differences in asthenozoospermic sperm samples.
BACKGROUND Asthenozoospermia is one of the most common findings present in infertile males, but its aetiology remains unknown in most cases. Present proteomic tools now offer the opportunity to identify proteins which are differentially expressed in asthenozoospermic semen samples and potentially involved in infertility. METHODS We compared the expression of 101 sperm protein spots in 20 asth...
متن کاملIncidence 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 کاملProteomic profile of human spermatozoa in healthy and asthenozoospermic individuals
Asthenozoospermia is considered as a common cause of male infertility and characterized by reduced sperm motility. However, the molecular mechanism that impairs sperm motility remains unknown in most cases. In the present review, we briefly reviewed the proteome of spermatozoa and seminal plasma in asthenozoospermia and considered post-translational modifications in spermatozoa of asthenozoospe...
متن کاملDifferential RNAs in the sperm cells of asthenozoospermic patients.
BACKGROUND Alterations in RNAs present in sperm have been identified using microarrays in teratozoospermic patients and in other types of infertile patients. However, so far, there have been no reports on using microarrays to determine the RNA content of sperm from asthenozoospermic patients. METHODS We started the present project with the goal of characterizing the RNA abundance in the sperm...
متن کاملApplication of proteomic methods for identification of sperm immunogenic antigens.
Although the immunogenic properties of sperm have been explored for a few decades, none of the antigens studied so far appears to be an effective target, to inhibit the fertilization process or shown the full spectrum of sperm antigenic potential. Antisperm antibodies (ASA) collected from infertile individuals and prepubertal boys with cryptorchidism together with two-dimensional (2D) electroph...
