This study was designed to analyze boar sperm to compare motility, acrosome morphology, viability and ATP by various preservation methods between Duroc boar A with cold shock resistance sperm and Duroc boar B with cold shock sensitivity sperm. Semen volume, sperm concentration, motility and normal acrosome between Duroc boar A and B did not show any differences within 2 h after collection. Ther...

STUDY QUESTION Does neutralization of apoptosis-associated speck-like protein containing a caspase activation and recruitment domain (ASC) improve sperm motility in men with spinal cord injury (SCI)? SUMMARY ANSWER Neutralization of ASC improves sperm motility in men with SCI. WHAT IS KNOWN ALREADY Semen of men with SCI contains normal sperm concentrations but abnormally low sperm motility....

Semen collection evaluation and addition of preservatives to increase storage period of sperm are essential for successful artificial insemination. This study was conducted on 4rams (2 Ghezel Merinos and 2 Merinos Moghani) to evaluate the effect of two diluents in Khalatposhan research station. Average age of rams was 3 years. Rams were trained to serve the artificial insemination and semen sam...

A new instrument for assessing mammalian semen attributes, the Sperm Quality Analyzer, was evaluated as a potential tool for determining rooster sperm quality. The Sperm Quality Analyzer measures the “activity” of sperm in a semen sample as the sperm motility index (SMI). The SMI is defined as the number and amplitude of deflections in a light path per second as a result of sperm movement wit...

BACKGROUND Tobacco smoking is a public health issue and has been implicated in adverse reproductive outcomes including semen quality. Available data however provides conflicting findings. The objective of this study was to evaluate the effect of tobacco smoking on semen quality among men in Ghana. METHODS In this study, a total of 140 subjects were recruited, comprising 95 smokers and 45 non-...

The present study was conducted to investigate the effects of butylated hydroxytoluene (BHT) supplementation on diluted, cooled and frozen-thawed ram spermatozoa. After primary evaluation of collected ejaculates, only semen samples with motility of more than 70% and sperm concentration higher than 3×10 sperm/ml were used for cryopreservation. The selected semen samples were then pooled and dilu...

AIM To assess the changes in semen parameters in men with spinal cord injury (SCI) and the possible causes of these changes. METHODS The study included 45 subjects with SCI. Semen retrieval was done by masturbation (2), vigorous prostatic massage (n = 13), penile vibratory stimulation (n = 13) or electroejaculation (n = 17). RESULTS The semen of men with SCI showed normal volume (2.3 +/- 1....

Background: Sperm preparation is a fundamental step in ART and attempt for developing new methods to be continued. Objective: To evaluate the efficacy of upstream method for separation of human spermatozoa and its effects on sperm parameters including: motility, morphology, and concentration. Materials and Methods: Semen samples from 17 men who referred to infertility clinic for evaluating thei...

The objective of this research was to verify the presence of spermatic abnormalities on semen of Brycon orbignyanus after cryopreservation. Semen was collected from ten four-year-old males who presented secondary reproductive characteristics for migrating fish. Sperm was evaluated for motility, vigor and spermatic morphology before and after cryopreservation. A cryoprotectant solution was made ...
