Influence of mini-Percoll techniques in sperm capacitation and plasma membrane integrity of ram frozen-thawed sperm. Author(s): OLIVARES, C. C. S.; ALFRADIQUE, V. A. P.; SOUZA FABJAN, J. M. G.; FONSECA, J. F. da; SARAIVA, H. F. R. A.; CÔRTES, L. R.; COSTA, L. C. da; BRANDÃO, F. Z. Abstract: The success of IVF and subsequent development of embryos are directly related to sperm selection and quality. This study aimed to evaluate the effect of different forces and time of centrifu... ... Repository: BDPA Publication year: 2016
Evaluation of boar and bull sperm capacitation and the acrosome reaction using flow cytometry. Author(s): PURDY, P. H.; GRAHAM, J. K.; AZEVEDO, H. C. Repository: BDPA Publication year: 2021
The influence of different methods of frozen-thawed ovine spermatozoa selection on sperm capacitation and viability after incubation. Author(s): OLIVARES, C. C. S.; SOUZA-FABJAN, J. M. G.; PENEIRAS, A. B. V.; BALARO, M. F. A.; FREITAS, V. J. F.; FONSECA, J. F. da; BRANDÃO, F. Z. Abstract: Sperm capacitation is an essential event for fertilization; however, it decreases the sperm lifespan and viability. The aim of this study was to evaluate the effects of four sperm selection... ... Repository: BDPA Publication year: 2015
Influence of caffeine and chondroitin sulfate on swine sperm capacitation and in vitro embryo production. Author(s): OLIVEIRA, V. P.; MARQUES, M. G.; ASSUMPÇÃO, M. E. O. D.; VISITIN, J. A. Repository: BDPA Publication year: 2011
Measurement of sperm capacitation and acrosome reaction - like changes by chlortetracycline test (CTC) can predict the freezability of ram semen? Author(s): AZEVEDO, H. C.; BICUDO, S. D.; SOUSA, D. B.; MAIA, M. da S.; RODELLO, L.; SICHERLE, C. C. The mixture was covered with coverslips, compressed, sealed. Repository: BDPA Publication year: 2008

Mini-Percoll processing of domestic ruminant frozen-thawed semen dispenses the use of heparin in capacitating medium. Author(s): OLIVEIRA, C. C. S.; SOUZA-FABJAN, J. M. G.; FONSECA, J. F. da; BATISTA, R. I. T. P.; BALARO, M. F. A.; SARAIVA, H. F. R. de A.; ALFRADIQUE, V. A. P.; CÔRTES, L. R.; BRANDÃO, F. Z. Sperm capacitation is a prerequisite for mammal successful fertilization. Although usually a capacitating substance such as heparin is used during sheep in vitro fertilization, evidences suggest that... ... Repository: BDPA Publication year: 2017
Comparison of different sperm selection techniques in ram frozen-thawed sperm. Author(s): OLIVARES, C. C. S.; SOUZA-FABJAN, J. M. G. de; FONSECA, J. F. da; BALARO, M. F. A.; FREITAS, V. J. de F.; OLIVEIRA, R. V. de; BRANDÃO, F. Z. Resumo: Background: The success of fertilization is directly associated with semen quality and the sperm preparation. Considering the common use of cryopreserved spermatozoa, there is a need to develo... ... Repository: BDPA Publication year: 2017
Mini-percoll technique induces Similar capacitation features in domestic ruminant frozen-thawed spermatozoa regardless of the presence of heparin. Author(s): ALFRADIQUE, V. A. P.; OLIVARES, C. C. S.; SOUZA-FABJAN, J. M. G. de; FONSECA, J. F. da; BATISTA, R. I. T. P.; BALARO, M. F. A.; SARAIVA, H. F. R. de A.; CÔRTES, L. R.; BRANDÃO, F. Z. Background: Sperm capacitation is a process consists of a series of functional, biochemical, and biophysical modifications that render the ejaculated sperm competent for oocyte fertilization. Secreted... ... Repository: BDPA Publication year: 2019
