Relationship of bull fertility to sperm nuclear shape.
The relationship between sperm nuclear shape and bull fertility was determined. Two groups of bulls, 3 per group, were selected. Bulls differed in fertility based on lifetime nonreturn rates. Digital images of propidium iodide-stained sperm from each bull were collected and shape-evaluated by Fourier harmonic amplitudes 0 to 5. A discriminant function (P < .05) was constructed based on harmonic...
متن کاملSperm Characteristics in Cryopreserved Buffalo Bull Semen and Field Fertility
Semen quality and its relationship to fertility are major concern in animal production. The aim of this study was to assess the relationship between frozen thawed sperm characteristics and fertility following in vivo fertility through Artificial Insemination(AI). Semen samples were collected from four buffalo bulls. Semen volume and sperm concentration appeared to be significantly different (P0...
متن کاملSperm Aneuploidy and Dna Integrity: a Review
Male factors leading to infertility account for at least half of all cases of infertility worldwide. The purpose of this review is to highlight the importance of sperm DNA integrity. A systematic literature search was performed up to January 2015 in order to determine the impact of sperm DNA integrity and of the techniques used to determine it. Only articles presenting sperm aneuploidy together...
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 کاملTestis specific histone 2B is associated with sperm chromatin dynamics and bull fertility-a pilot study
BACKGROUND Bull fertility is the degree of sperm's ability to fertilize and activate the egg and support embryo development, and this is critical for herd reproductive performance. We used the bull as a unique model organism for the study of male fertility because cattle genetics and physiology is similar to those of other mammals including humans. Moreover, reliable fertility data along with w...
