Comparative assessment of thawing methods for frozen rooster sperm

open access: yesFrontiers in Veterinary Science
IntroductionCryopreservation, widely used in commercial poultry breeding, often reduces sperm motility, viability, and DNA integrity due to cryopreservation-induced damage.

Sperm Sexing in Selected Animals and Humans: Methods, Applications, and Future Prospects

open access: yesAndrology, EarlyView.
ABSTRACT Background Sperm sexing is a technique that enables the selection of offspring sex by sorting spermatozoa based on their sex chromosomes. This technology has gained increasing attention due to its potential applications in both animal breeding and human‐assisted reproduction.

Limited Utility of a Test‐Yolk Buffer Semen Extender for Preserving Human Semen Parameters for Use in a Diagnostic Setting

open access: yesAndrology, EarlyView.
ABSTRACT Background Identification of a preservation medium that accurately retains semen parameters would be advantageous for men requiring semen analysis by allowing them to produce sperm samples at home rather than on site or even facilitate ‘mail order’ semen analysis.

The Effect of Cholesterol‐Loaded Cyclodextrin and Resveratrol Compounds on Post‐Thawing Quality of Ram Semen

open access: yesVeterinary Medicine and Science
Ram sperm are more vulnerable to freezing than those of most other farm animals. During sperm freezing, the cell membrane loses some of its cholesterol, which regulates signalling mechanisms and prevents premature capacitation.

Does synchronising follicular wave emergence improve outcomes in non‐superstimulated donor cattle undergoing ovum pick‐up (OPU) for in vitro embryo production?

open access: yesAustralian Veterinary Journal, EarlyView.
In vitro embryo production (IVEP) is now a widely commercialised assisted reproductive technology used in cattle reproduction. The use of follicle‐stimulating hormone (FSH) to superstimulate donor cattle prior to ovum pick‐up (OPU) is generally regarded as an effective strategy to improve oocyte quality, developmental competence and increase embryo ...

Effects of Resveratrol-Loaded Cyclodextrin on the Quality Characteristics of Ram Spermatozoa Following Cryopreservation

open access: yesAnimals
This study investigated the effects of pure and methyl-β-cyclodextrin loaded forms of resveratrol (10 µg/mL, 20 µg/mL, and 40 µg/mL) on ram sperm functions post-thawing. Semen samples were pooled and divided into ten groups: Control, RES10, RES20, RES40,

Impact of Female Mating Status on Male Courtship Behaviour in a Sexually Cannibalistic New Zealand Fishing Spider

open access: yesEthology, EarlyView.
Scoring of male courtship behaviour in Dolomedes minor revealed no effect of female mating status on courtship duration or sequence structure, but males delayed the initiation of courtship when encountering previously mated females. ABSTRACT The evolution of male courtship rituals has traditionally been attributed to female mate selection, but may also

The effect of green tea extract supplementation in bull semen cryopreservation [PDF]

open access: yesKafkas Universitesi Veteriner Fakültesi Dergisi, 2019
This study aims to investigate the effect of catechin (CT), green tea extract, as a supplement to Tris extender on semen quality parameters in frozen-thawed of bull sperm. Ejaculates were taken with artificial vagina from Holstein bulls and divided equal
