Abstract

Purpose

To compare the expression profiles of Tektin 2 and CatSper 2 motility proteins in the spermatozoa of normozoospermic and oligoasthenozoospermic men and determine its correlation with sperm motility, fertilization rate, embryo quality and pregnancy rate.

Methods

Tektin 2 and CatSper 2 protein expression was studied using Western Blotting and immunofluorescence. Tektin 2 and CatSper 2 protein levels were quantified by ELISA.

Results

Oligoasthenozoospermic men were found to have lower fertilization rates, poor embryo quality and lower pregnancy rates as compared to normozoospermic men. The levels of Tektin 2 and CatSper 2 are significantly lower in spermatozoa of oligoasthenozoospermic men as compared to normozoospermic controls; the levels were also lower in immotile fraction as compared to motile fraction of spermatozoa obtained from normozoospermic individuals. The levels of Tektin 2 and CatSper 2 were higher in individuals demonstrating sperm motility >60 % as compared to sperm motility <30 %. Tektin 2 but not CatSper 2 levels were positively associated with fertilization rate, embryo quality and pregnancy rate.

Conclusion

Levels of Tektin 2 and CatSper 2 proteins are positively associated with sperm motility parameters. Measurements of Tektin 2 levels can be correlated with the clinical outcome of ICSI.

Hirsutismus bei PCOS: Laser- und Lichttherapien helfen

26.04.2024 Hirsutismus Nachrichten

Laser- und Lichtbehandlungen können bei Frauen mit polyzystischem Ovarialsyndrom (PCOS) den übermäßigen Haarwuchs verringern und das Wohlbefinden verbessern – bei alleiniger Anwendung oder in Kombination mit Medikamenten.

ICI-Therapie in der Schwangerschaft wird gut toleriert

Müssen sich Schwangere einer Krebstherapie unterziehen, rufen Immuncheckpointinhibitoren offenbar nicht mehr unerwünschte Wirkungen hervor als andere Mittel gegen Krebs.
