Maintaining a successful pig artificial insemination programme depends on a number of factors, including evaluation of semen characteristics. This study compared the efficacy of different extenders on the sperm motility of Kolbroek semen during short term storage at 4 °C and 25 °C. Semen was collected from Kolbroek boars using the gloved hand technique and transported to the laboratory for eval...

This study aimed to analyze the effects of different osmolalities on the characteristics of spermatozoa originating from whole ejaculates (WE; including the prostatic fluid) and the sperm-rich fractions (SRF). Ejaculates, collected from four mixed-breed dogs, were exposed for 10 min at room temperature to Tris-fructose-citrate (TFC) solution with osmolality ranging from 150 to 1100 mOsm. After ...

This study investigates the effect of supplementing bovine follicular fluids (FF) to rabbit sperm motility, acrosome reaction and transaminases activities. Ovarian FF were collected from 46 pairs of bovine ovaries. Normal follicles were classified, according to their diameters, into small (SFF, ≤4 mm), medium (MFF,>4-8 mm), large (LFF,> 8 mm) and cystic (CSTFF,>20 mm). Rabbit semen was collecte...

Tauopathies are neurodegenerative diseases based on pathological tau-aggregation including Alzheimer's disease, frontotemporal dementia (FTD) and Pick's disease. In general, cargo (e.g., β-amyloid precursor protein, tau, neurofilaments) accumulation is a commonly observed phenomenon in degenerated neurons. Therefore, it is crucial to investigate the interaction between cargo, microtubule-bindin...

UNLABELLED Study Type - Outcomes (cohort series). Level of Evidence 2b What's known on the subject? and What does the study add? Microsurgical vasectomy reversal is an effective and cost-effective method of reinstating fertility in a man who has previously had a vasectomy. The current literature indicates that the success rate (i.e. potency and pregnancy rates) are dependent primarily on the ti...

This research was carried out to investigate the effects of various levels of dietary organic selenium supplementation (0, 0.1,  0.2 and  0.3 mg/Kg) on reproductive traits of rooster. Semen was collected using abdominal massage and samples were mixed together. Sperm characteristics including percentage of motile, viable and abnormal sperms were assessed. This experiment was carried out based on...

the aim of this study was to evaluate changes that occur in motility parameters of progesterone treated mouse spermatozoa during course of hyperactivation. mouse spermatozoa treated with different doses of progesterone were videotaped after 10 min and 90 min of incubation. for each sperm, one second of movement of the head-midpiece junction was traced from the videotape and for each tracing sev...

The effects of different dilutions of seminal plasma (SP) on the qualitative characteristics of rabbit spermatozoa and on their fertilising ability were analysed. Ejaculated semen was centrifuged twice and the sperm resuspended in media with decreasing ratios of SP/Tris: (1/2; 1/5; 1/10; 1/20; 1/30; 1/100) until the complete substitution was with SP. The control constituted sperm in undiluted S...
