Background: To current knowledge, different oocyte's recovery method and various seasons have profound impact on in vitro embryo production (IVEP).
Our study focused on a retrospective analysis from 2004-2011 of patients considering elective oocyte cryopreservation (OC). We investigated the psychological and social aspects related to women who el...
The optimal anesthetic technique for transvaginal ultrasound guided oocyte retrieval (TUGOR) is not known. We present a case series of patients having TUGOR under intravenous remifentanil infusion and...
Sperm binding to the oocyte plasmalemma is crucial to subsequent steps in fertilization. However, the usual in vitro assay for sperm-oocyte binding does not distinguish between nonspecific attachmen...
The objective of this study was to examine the effects of reactive oxygen species (ROS) on bovine sperm function and on the developmental competence of in vitro-matured bovine oocytes. In a first se...
The authors studied hyperactivated motility of human spermatozoa as a method of evaluating capacitation by examining its relationship to results of zona-free hamster oocyte sperm penetration assays ...
Initial in vitro fertilization (IVF)–embryo transfer studies found poor fertilization and pregnancy rates following conventional fertilization of oocytes when using sperm with <4% normal morpholo...
Several pregnancies have been reported using frozenthawed testicular sperm (Fisher et al, 1996; Podsiadly et al, 1996; Khalifeh et al, 1997), stressing the role of sperm motility for successful outc...
A fertile bull producing normal sperm and a sterile half brother exhibiting 100% teratospermia were available to study an induced sperm acrosome reaction and oocyte penetration. Pedigree analysis in...
In the present study the kinetics of glutathione (GSH) concentration during in vitro maturation in the presence of Cysteamine in culture medium was examined. Also the effects of different doses of Cys...
