Effect of swim-up sperm washing and subsequent capacitation on acrosome
status and functional membrane integrity of normal sperm.
Effects of cryopreservation on human sperm acrosomes
ABSTRACT: Effect of two antioxidants (Taurine and Manganese) in extender on different sperm parameters (sperm motility, live sperm percentage, membrane and acrosome
integrity) of Sahiwal bulls was evaluated.
HBPs have been viewed as favouring capacitation, acrosome
reaction, and altering the immune system response toward the sperm.
Success of fertilization depends on various cellular characteristics of the spermatozoa such as membrane and acrosome
integrity, mitochondrial activity, and production of reactive oxygen species (ROS) (Lu & Wu 2005, Espinoza et al.
more or less oval head shapes with less condensed chromatin, partially present and even invaginated acrosomes
The database included the seminal variables: concentration, morphology (head, mid piece and tail), membrane structural integrity (MSI), acrosome
integrity (ACRI), and membrane functional integrity (MFI); proximal cytoplasmic droplet, (PCD), distal cytoplasmic droplet (DCD), and total cytoplasmic droplets (TCD).
The supravital stain trypan-blue was used to distinguish live and dead spermatozoa while giemsa stain was used to evaluate the integrity of the acrosome
To be viable, sperm must have intact acrosomes
(Bearden & Fuquay, 1999; Schmitt & Webb, 2002).
2) Glycocalyx also plays an important role in sperm protection against the female immune system, acrosome
reaction, and ability of the sperm to fertilize oocytes.
