Comparison of in Vitro Fertilization Rates of Oocytes and Embryo Development Using Two Techniques of Semen Processing

Comparison of in Vitro Fertilization Rates of Oocytes and Embryo Development Using Two Techniques of Semen Processing

The investigators propose to assess one method of sperm selection based on the characteristics of spermatozoa recently introduced: Sperm Selection Assay, which used a gradient of concentration of progesterone to act as chemoatractant of spermatozoa of better quality. We will assess in vitro fertilization with two techniques (SSSA versus traditional technique of swin up) as well as embryo development.
