متن کاملSemen Quality Factors Associated with Fertility
Introduction: Since the early 60s, in our lab we sought useful correlations of seminal traits and fertility in order to ultimately predict the reproductive outcome of bovine semen used in artificial breeding or the fertility of a specific male under natural service. Despite these efforts, to this day we can only account for approximately 50-60% of the variation in fertility among males by measu...

متن کاملsperm ubiquitination correlation with human semen quality
background: ubiquitin, an 8.5 kda peptide that marks other proteins for proteasomal degradation, tags defective sperm during epididymal passage. thus, sperm ubiquitination is a universal marker for sperm defects and can be used as a sperm function test. the objective of the present study was to examine the relationships between sperm ubiquitination and clinical semen parameters, using simpl...
متن کاملAntioxidant intake is associated with semen quality in healthy men.
