Reaction of fresh and frozen bull spermatozoa incubated with fresh and frozen bovine oviduct epithelial cells.
The hypothesis was tested that frozen bovine oviduct epithelial cells (BOEC) could provide a physiologic and standardized system for studying motility and acrosomal changes of fresh and frozen-thawed sperm. The BOEC were collected by lavage from cows and monolayers prepared from both fresh and frozen-thawed cells. Fresh and frozen semen processed from five bulls was extended in a modified Tyrod...
متن کاملExpression of miRNAs in Bull Spermatozoa Correlates with Fertility Rates.
Bull spermatozoa are rich in active miRNAs, and it has been shown that specific spermborne miRNAs can be linked to fertility. Thus, expression profiling of spermatozoa could be helpful for understanding male fertility and the ability of spermatozoa to initiate and sustain zygotic, embryonic and foetal development. Herein we hypothesized that bulls with moderate to high fertility can be identifi...
متن کاملBull Fertility and Its Relation with Density Gradient Selected Sperm
Background sperm selection is generally used to describe methods for separation of spermatozoa for in-vitro-assisted reproduction. Few studies reported relation in vivo fertility and semen parameters after selection of fertile spermatozoa; hence, our research attempt to assess different semen parameters after post-thaw (PT) or after selecting sperm sample (SSp), using density gradient separatio...
متن کاملa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولO-12: Studies on Sequestration of PDC-109 Protein on Cryodamage and In Vitro Fertility of Crossbred Bull Spermatozoa
Background: Plasma membrane of the spermatozoa interacts with and is altered by abundant seminal PDC-109 present in their immediate milieu in vivo with damaging effect in a time- and concentration- dependent manner. Therefore we hypothesized that sequestration of detrimental protein from ejaculates would be beneficial for cryopreservation of sperm cells. To this aim we evaluated the effect of s...
