Abstract

In the context of artificial insemination, male fertility is defined as the ability to produce functional spermatozoa able to withstand cryopreservation. We hypothesized that interindividual variations in fertility depend on the proportion of the fully functional sperm population contained in the ...

Abstract

Objective: To evaluate effect of tris-extender supplemented with various concentrations of strawberry (Fragaria spp.) on bull semen preservability. Methods: Pooled bull semen were extended with tris-citrate-fructose egg yolk diluent (control, 0% strawberry) and various concentrations of tris...

Abstract

Prediction of male fertility with in vitro semen quality parameters remains a challenge for the bull industry. Fluorescein staining and computer-assisted semen analysis (CASA) ensure kinetically proper and functionally objective results to improve spermatological parameter control. Therefore, we...

AbstractFull Text

Equilibration is the one of the important steps of semen cryopreservation and it is the stage in which semen is cooled and phase changes occur. The condition of equilibration is mostly regarded; and success of the equilibration conditions depend on empirical experiences. The aim of this study was...

AbstractFull Text

Computer Assisted Sperm Analysis (CASA) represents an objective, reproducible and reliable method of sperm quality assessment, however, not many reports exist that correlate its accuracy with bull semen fertility. The aim of this study was to evaluate the correlation between selected CASA motility...

Abstract

BACKGROUND: The membrane and acrosomal integrity of sperm play a vital role in fertilization process; however they are compromised upon cryopreservation. OBJECTIVE: To study the effect of cholesterol-loaded cyclodextrin (CLC) on membrane and acrosome status of Hariana bull sperm during...

Abstract

The present study aimed to investigate effects of superoxide dismutase (SOD) and reduced glutathione (GSH) on the quality of frozen-thawed semen of Sahiwal bulls. Semen was collected twice a week for 8 weeks by artificial vagina from six Sahiwal bulls, kept at the Semen Production Unit Qadirabad,...

Abstract

Sixty-four ejaculates (eight from each bull) were collected from matured bulls. Ejaculates were classified into the freezable (n=49) and non-freezable (n=15) based on the initial parameters (motility ≥70%, mass activity ≥3 and post-thaw motility 50%). Correlation between functional and biochemical...
