Background: To evaluate whether success of fertilization and embryo quality are more probable when follicular fluid Anti-mullerian hormone levels are higher . Materials and Methods: 62 women who underwent IVF cycle were divided into fertilized oocytes group (n=42) and non- fertilized oocytes group (n=20) . Follicular fluid Anti-mullerian hormone levels were measured in both groups. Results: Ant...

BACKGROUND The aim of this study was to evaluate the impact of transferring a single top quality embryo in the first IVF/ICSI cycle of patients <38 years old who chose to have one or two embryos transferred. METHODS A total of 262 patients participated in the study, and 243 transfers were performed: 156 (64%) patients chose the transfer of a single top quality embryo, if available, and two no...

STUDY QUESTION Are there associations between early time-lapse parameters, expression of candidate embryo viability genes in cumulus cells and embryo quality on Day 5? SUMMARY ANSWER Early time-lapse parameters correlate to the expression levels of candidate embryo viability genes in cumulus cells but a combined analysis including both time-lapse and candidate gene expression did not identify...

Background -Recurrent pregnancy loss defined as two or more miscarriage before 20 weeks of pregnancy affecting 1-5 % or women in reproductive age .There are many etiologies have been suggested, like Genetic, Immunologic, Thrombophila, Endocrine and Anatomic; but in 50% of cases, the exact etiology remains uncertain. Endometrium acts as biosensor of embryo quality and endometrium itself contribu...

It is well known that egg storage reduces embryo performance, but the fundamental reasons for reduced embryo quality remain unclear. The objective of this study was to investigate possible cellular and molecular mechanisms that might reduce embryo quality after egg storage. Broiler hatching eggs were obtained from the Ross 308 broiler strain, divided into 2 groups, and stored (4 and 14 d) under...

background: multiple factors have been suggested for prediction of pregnancy in intracytoplasmic sperm injection (icsi) cycles such as the number of injected oocytes, fertilization rate, embryo morphology and quality of transferred embryos. predictive value of these factors is important in icsi outcome. objectives: to evaluate the role of embryo morphology for prediction of pregnancy in icsi cy...

improvements on embryo micromanipulation techniques led to the use of embryo biopsy in commercial embryo transfer programs for genetic analysis of preimplantation bovine embryos. the aim of this study was to evaluate the quality of bovine blastocyst derived from embryos biopsied at different precompacted morulae stages by assessment of cryosurvivability of the resulting blastocysts. the in vitr...
