Factors influencing boar sperm cryosurvival.
Optimal sperm cryopreservation is a prerequisite for the sustainable commercial application of frozen-thawed boar semen for AI. Three experiments were performed to identify factors influencing variability of postthaw sperm survival among 464 boar ejaculates. Sperm-rich ejaculate fractions were cryopre-served using a standard freezing-thawing procedure for 0.5-mL plastic straws and computer-cont...
متن کاملFactors influencing visual outcome in anisometropic amblyopes.
AIM To identify which factors influence the final visual acuity in children with anisometropic amblyopia. METHODS A retrospective analysis of 112 children with anisometropic amblyopia, identified from examining all case notes of children who had failed preschool or school screening. RESULTS The age at presentation had no effect on the final visual outcome (p=0.804). Both the degree of refra...
متن کاملFactors influencing sperm retrieval following testicular sperm extraction in nonobstructive azoospermia patients
OBJECTIVE Azoospermia owing to testicular disorders is the most severe manifestation of male infertility. The main concern for patients with nonobstructive azoospermia (NOA) is the probability of successful sperm retrieval following testicular sperm extraction (TESE). Therefore, the goal of this study was to determine predictive factors correlated with sperm retrieval. METHODS We assessed the...
متن کاملFactors influencing human sperm kinematic measurements by the Celltrak computer-assisted sperm analysis system.
This study examines the effect of varying several factors, both extrinsic and technology-dependent, on the reconstruction of human sperm trajectories and the derived kinematic measurements using videotapes and the Motion Analysis Celltrak/S instrument. In semen samples from normal healthy men, curvilinear (VCL) and straight line velocities (VSL) were found to increase 1.5-fold, and linearity (L...
متن کاملSperm preparation for ART
The onset of clinical assisted reproduction, a quarter of a century ago, required the isolation of motile spermatozoa. As the indication of assisted reproduction shifted from mere gynaecological indications to andrological indications during the years, this urged andrological research to understand the physiology of male germ cell better and develop more sophisticated techniques to separate fun...
