clinical reproductive centers produce large amounts of surplus poor-quality embryos annually, how to maximize the use of these embryos, and which of them have the potential to develop into blastocyst stage and influencing factors were lack of systematic research. objective: to investigate the fate of surplus poor-quality embryos which were cultured to obtain blastocyst, determine the factors wh...
Comparison of Embryo Quality Cultured in Ham's F-10+%10 Maternal Serum and GIIII S.G.A. Jorsaraie PhD , M. Zeinalzadeh MD , T. Nazari MD2, Y.R. YousofniaPasha MD A.A. Beiki MPh , A. Bazram GP Received: 10/01/07 Sent for Revision: 17/04/07 Received Revised Manuscript: 07/08/07 Accepted: 26/08/07 Background and Objectives: Appropriate culture media and environment for embryonic cell growth consid...
Background: Last decades, we have observed major improvements in treating infertility by using microinjection. However, reduction in abortion or increase in fertility has not been significant. It seems use of corticosteroids improves clinical outcomes during assisted reproductive technology (ART) techniques. Therefore, this study tried to show how corticosteroids therapy improves the results of...
Oocyte Scoring Enhances Embryo-Scoring in Predicting Pregnancy Chances with IVF Where It Counts Most
CONTEXT Our center's quality improvement optimization process on many occasions anecdotally suggested that oocyte assessments might enhance embryo assessment in predicting pregnancy chances with in vitro fertilization (IVF). OBJECTIVE To prospectively compare a morphologic oocyte grading system to standard day-3 morphologic embryo assessment. DESIGN, SETTING, PATIENTS We prospectively inves...
OBJECTIVE To describe a patient selection method for elective single embryo transfer (eSET), emphasizing inclusion criteria and results. METHODS This retrospective study included all cases seen in a private clinic between June 2011 and December 2016, in La Paz, Bolivia (3600 meters above sea level). Elective single embryo transfer was the method of choice in 34 IVF/ICSI cycles, all in the bla...
OBJECTIVES In assisted reproductive technology, it is important to choose high quality embryos for embryo transfer. The aim of the present study was to determine the grade A embryo count and factors related to it in infertile women. MATERIALS AND METHODS This historical cohort study included 996 infertile women. The main outcome was the number of grade A embryos. Zero-Inflated Poisson (ZIP) r...
Background The purpose was to investigate the effect of the duration of gamete incubation on fertilization rate, embryo cleavage, and embryo quality before and after freezing in mice. MaterialsAndMethods Ovulated oocytes collected from superovulated mice after ip injection of PMSG and hCG were divided randomly into control and experimental groups. Oocytes from the control group were inseminated...
A model was developed for the economic evaluation of embryos for producing bull lines for use in commercial beef production. The fundamental concept underlying the model is that a cloned and sexed embryo of known genetic characteristics for beef traits is used to produce a bull. After reaching physiological maturity, the bull is used in natural matings. Equations relating feed energy requiremen...
Background: This retrospective study compared pregnancy outcomes from single embryo transfer (SET) with multiple embryo transfer (MET) in too young (≤25 years) and young (>25 years) infertile patients. Materials and Methods: Data from infertile patients who referred for ART treatment to Yazd infertility center during 1992 to 2012 were studied retrospectively. Records of patients with SET or MET...
