Evaluation of cooling and freezing systems of bovine semen
(2018-08-01)
Semen cryopreservation comprises different steps, among them are the cooling and freezing rates which significantly influence the quality of thawed sperm. Different systems with variable freezing rates are used for freezing ...
Evaluation of Sperm Kinetics and Plasma Membrane Integrity of Frozen Equine Semen in Different Storage Volumes and Freezing Conditions
(2013-03-01)
In the present study, different freezing systems (Styrofoam box and Mini Digitcool ZH 400) and storage volumes (0.5- and 0.25-mL straws) were compared with regard to sperm kinetics and plasma membrane integrity of frozen ...
Influência do uso de diferentes crioprotetores e número de palhetas sobre o tempo de congelamento
(2022)
A taxa de congelamento é um dos processos que causam grandes mudanças na
célula, e a busca por taxas de congelamento ótimas pode minimizar fatores
prejudiciais desse processo. Neste trabalho o objetivo foi determinar as ...

Two-step accelerating freezing protocol yields a better motility, membranes and DNA integrities of thawed ram sperm than three-steps freezing protocols
(2019)
The present study compares a protocol that mimics freezing of ram semen in static nitrogen vapor with two protocols with an initial low cooling rate in the first step, followed by higher cooling rates where ice nucleation ...
