Although the percentage of progressive motility was similar, percentage of viable cells decreased in group H1, while percentage of acrosomal
integrity was major in H1 than in H2.
The polypeptide backbone of recombinant human zona pellucida glycoprotein-3 initiates acrosomal
exocytosis in human spermatozoa in vitro.
argo the axonemal basis migrates to the anterior part of the nucleus and is finally located close to the acrosomal
region of the head should stain light blue and the postacrosomal region should stain dark blue.
Reactive oxygen are responsible to sperm membrane damage and directly damage sperm DNA that cause reduces of the sperm's motility, acrosomal
membrane integrity and sperm metabolic alterations.
Sperm motility, viability and acrosomal
integrity were assessed at 0, 0.
9, black bars), most sperm still exhibited a normal head bearing acrosomal
vesicles with no anterior projections.
Structural integrity of acrosomal
membrane is dependent upon sialic acid and due to alteration in its content the metabolism, motility and fertilizing ability of sperms may also be affected (Riar et al.
The relatively small and flat acrosomal
vacuole is attached to the disc-like nucleus.
The second, third and fourth steps of this process, respectively, are the acrosomal
reaction, the sperm cell and egg cell adhesion through the vitelline envelope, and the actual membrane contact between the two cells.
This result showed that L-carnitine supplementation in freezing extender could not protect cat cryopreserved epididymal spermatozoa against acrosomal
Chapters 8 and 9 discuss the tests such as antisperm antibodies, seminal fluid analysis, acrosomal
integrity and function, sperm cervical mucus interaction and sperm chromatin.
