OBJECTIVE To investigate fertilization and embryo quality of dysmorphic mature oocytes with specific morphological abnormalities obtained from intracytoplasmic sperm injection (ICSI). METHODS The fertilization rate (FR) and embryo quality were compared among 58 dysmorphic and 42 normal form oocytes (control 1) obtained from 35 consecutive ICSI cycles, each of which yielded at least one dysmor...

the aim of this study was to analyze the incidence of stage of embryonic development, embryo quality and the time of transfer on pregnancy rate in embryo transfer program timed. we were worked a total of 23holsteincowsasembryo donors, super-ovulated with gonadotropin of pregnant mare serum (pmsg) (2500 3000ui).69 cows were used as recipients of holstein dairy heifers with an age of20 months and...

background: abnormal oocyte morphology has been associated with the hormonal environment to which the gametes are exposed. objective: in this study, we evaluated the oocytes morphology, fertilization rate, embryos quality, and implantation rate resulted of retrieved oocytes in different times after human chorionic gonadotrophin (hcg) administration. materials and methods: a total of 985 metapha...

INTRODUCTION In several clinics, elective single-embryo transfer (eSET) is applied in a selected group of patients based on age and the availability of a good-quality embryo. Whether or not eSET can be applied irrespective of the presence of a good-quality embryo in the first cycle, to further reduce the twin pregnancy rate, remains to be elucidated. METHODS In patients <38 years two transfer...

background: determination of oocyte and embryo quality are one of the most important goals in ivf. anti-mullerian hormone (amh) is secreted by the ovarian granulosa cells into blood flow and follicular fluid. follicular fluid anti-mullerian hormone level is probably a marker of activity of granulose cells. objective: to evaluate whether high level of follicular fluid anti-mullerian hormone leve...

Embryo quality is a key determinant of the success IVF. Although focus has been on selecting best embryo for transfer, classification low-grade blastocysts (LGB) in existing scoring systems received less attention. This worrisome; freezing allows optimal use all created embryos, thus maximizing cumulative live birth rate, which arguably most important outcome infertile couples. A PubMed search ...

Morphological embryo classification is of great importance for many laboratory techniques, from basic research to the ones applied to assisted reproductive technology. However, the standard classification method for both human and cattle embryos, is based on quality parameters that reflect the overall morphological quality of the embryo in cattle, or the quality of the individual embryonic stru...

conclusions sperm quality extracted by percutaneous pesa and tese procedures increases fertility outcomes compared to naturally ejaculated sperm in men with idiopathic co. more specifically, embryo quality, which is most relevant to fertility outcome, improved when surgically extracted sperm was used for icsi. results there was a significant difference in fertilization rate, embryo quality, imp...
