In Vitro Ovine Embryo Production:the Study of Seasonal and Oocyte Recovery Method Effects
In Vitro Oocyte Maturation Techniques Fertilization in Vitro Embryo Production Sheep Oocytes
2015/10/14
Background: To current knowledge, different oocyte's recovery method and various seasons have profound impact on in vitro embryo production (IVEP).
Social and psychological assessment of women undergoing elective oocyte cryopreservation: A 7-year analysis
Eelective Oocyte Cryopreservation Basal Antral Follicle Count (BAFC)
2013/1/31
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...
Remifentanil Infusion and Paracervical Block Combination for Transvaginal Ultrasound Guided Oocyte Retrieval
Oocyte retrieval paracervical block remifentanil
2009/6/23
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...
An improved mouse sperm-oocyte plasmalemma binding assay: studies on characteristics of sperm binding in medium with or without glucose
Zona-free oocytes pronuclear zygotes in vitro fertilization
2009/2/18
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 impact of reactive oxygen species on bovine sperm fertilizing ability and oocyte maturation
Spermatozoa fertilization development xanthine oxidase
2009/2/17
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...
Evaluation of human sperm hyperactivated motility and its relationship with the zona-free hamster oocyte sperm penetration assay
Motility capacitation fertilizing capacity
2009/2/7
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 ...
A Retrospective Comparison of Pregnancy Outcome Following Conventional Oocyte Insemination vs Intracytoplasmic Sperm Injection for Isolated Abnormalities in Sperm Morphology Using Strict Criteria
In vitro fertilization zona pellucida subfertile male
2008/12/24
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...
Successful Pregnancy and Delivery Following Intracytoplasmic Injection of Frozen-Thawed Nonviable Testicular Sperm and Oocyte Activation With Calcium Ionophore
Successful Pregnancy Delivery Intracytoplasmic Injection Frozen-Thawed Nonviable Testicular Sperm Oocyte Activation
2008/12/24
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...
Induction of the acrosome reaction and zona-free hamster oocyte penetration by a bull with complete teratospermia versus a half brother with normal sperm
zona-free hamster oocyte penetration bull complete teratospermia
2008/12/1
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...
Intracytoplasmic glutathione level in MII oocyte during in vitro maturation of germinal vesicle: Effect of cysteamine
Germinal Vesicle In vitro maturation of oocyte Cysteamine Glutathione
2010/4/6
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...
