摘要: Purpose During the past few years, many oocyte insemination techniques, including microinjection, have evolved in treatment of male-factor infertility. This preliminary study was designed to evaluate whether microdroplet could be considered a reliable technique, especially for semen samples with defects. The first objective assess fertilization rates obtained by inseminating sibling oocytes using both conventional IVF and method (Group 1). second subsequent embryo development pregnancy resulting from insemination, addition formulating adequate sperm∶ ratios various categories 2). Four were studied fresh normal sperm, frozen/thawed sperm one defect two or three
