Relationship between acrosin activity of human spermatozoa and oxidative stress.
AIM To study the association between seminal oxidative stress and human sperm acrosin activity. METHODS It is a prospective study consisting of 30 infertile men and 12 fertile normozoospermic volunteers. A full history, clinical examination and scrotal ultrasound were done to exclude other related factors such as smoking and varicocele. Presence of white blood cells (WBCs) in semen samples wa...
متن کاملDemonstration of acrosin in mouse spermatozoa.
Gelatinolytic activity of whole mouse spermatozoa was demonstrated by the gelatin film test. The presence of a trypsin-like protease (acrosin) in acidic extracts of mouse spermatozoa was shown by an electrophoretic method to separate the enzyme from a putative inhibitor.
متن کاملVitrification induced apoptosis in spermatozoa from fertile and subfertile men
Background: Phospholipids are distributed asymmetrically between inner and outer leaflets of the plasma membrane of live cells. Early during apoptosis, this asymmetry is disrupted and phosphatidylserine becomes exposed on the outside surface of the plasma membrane. There is little information about the effects of vitrification on apoptosis. Objective: The aim of the present study was to evaluat...

متن کاملRNA dynamics of fertile and infertile spermatozoa.
The presence of a complex population of mRNAs in human mature spermatozoa is well documented; among them, transcripts of aromatase and ERs (oestrogen receptors) have been described but their significance is not clear. Therefore, to clarify the role of this complex population of mRNAs in human ejaculated sperm, we have isolated on discontinuous density gradients two main fractions from the same ...
