...30 seconds and post-thaw sperm quality parameters were assessed. Sperm progressive motility, plasma membrane integrity, acrosomal integrity, viability and chromatin integrity was higher (P<0.05) in extender containing melatonin 0.1 mM and 0.5 mM compared to control. In conclusion, the addition of melatonin 0.1-0.5 mM to extender improved the post-thaw quality of buffalo bull semen.

...Freezing process reduces sperm quality due to membrane damage. Antioxidants protects the membrane of spermatozoa. This study aimed to observe the effects of Snakehead Fish (Channa striata [Bloch 1793]) Extract (SFE) supplementation in tris Egg-yolk extender on mortality and motility of spermatozoa of Limousin bull (Bos primigenius f. taurus [Linnaeus, 1758]) collected from Singosari Artific...

...ic testicular index, and sperm quality in the G3 group, nevertheless, there was a significant (P<0.05) increase in LH, FSH, sperm abnormalities percent, and dead sperm percent in the G3 group. The capacity of Phitofert ® to restore all passive effects of CCL4 and increase epididymal sperm quality was demonstrated in G4 groups.

...om various parameters of sperm quality. Good sperm quality is very influential on reproductive efficiency. Vitamin E plays a role in male fertility because it can increase testicular weight, sperm count or concentration, sperm motility, and vitality. L-carnitine is an amino acid compound and is able to provide energy so that it can help improve sperm quality. The objectives of this resear...

...LP method. Evaluation of sperm quality in terms of concentration, volume, motility, and sperm viability was performed using photometry, flow cytometry, and a computer assisted sperm analyzer. The above studies indicate that all four nucleotide substitutions analyzed in exon 4 of AQP7 gene affect the individual quality characteristics of the analyzed semen of Holstein-Friesian bulls.
