Efficacy of oocyte vitrification combined with blastocyst stage transfer in an egg donation program.
BACKGROUND A successful oocyte vitrification program is important for women with various indications for assisted reproduction technology. The objective of this study was to report the outcome of vitrification of oocytes, obtained through an oocyte donation program, by evaluating the embryo development, pregnancy and implantation rates (IRs) after blastocyst transfer. METHODS A total of 1098 oo...
متن کاملP-121: Which Developmental Stage is Suitable for Re-vitrification? Compact Stage Re-vitrification or Early Blastocyst Stage Re-vitrification
Background: The aim of this study was evaluation of developmental rate and Bax, Bcl-2 and ErbB4 genes expression following re-vitrification in compact and early blastocysts stages. Materials and Methods: 5-8 cell embryos were collected from female mature mice, 60-62 hours post hCG injection. The embryos were divided to five groups including: fresh, vitrified at 5-8 cells, vitrified at blastocys...
متن کاملCumulative ongoing pregnancy rate achieved with oocyte vitrification and cleavage stage transfer without embryo selection in a standard infertility program
BACKGROUND Recent advancement of minimum volume vitrification methods has resulted in a dramatic increase in the efficiency of the process. The aim of this study was to estimate the cumulative reproductive outcome of a cohort of infertile couples undergoing ICSI and oocyte vitrification in restrictive legal conditions, where only a limited number of oocytes could be inseminated per cycle and em...
متن کاملClinical validation of a closed vitrification system in an oocyte-donation programme.
Controversy exists about the risk of microbiological contamination from direct contact with unsterile liquid nitrogen during oocyte vitrification. The aim of this observational study was to evaluate the effectiveness of oocyte vitrification using a high-security closed vitrification system in a donation programme. Oocyte vitrification was performed using CBS High Security closed straws (Cryo Bi...
متن کاملOocyte Donation: an Overview
The use of donor oocytes has expanded the scope of assisted reproductive technology (ART) for women with poor oocyte quantity and quality. In vitro fertilisation with oocyte donation (IVF-OD) is considered to give better implantation, pregnancy, and livebirth rates compared to IVF with autologous oocytes. Maternal age, infertility factors, BMI, smoker status, and ethnicity reduce reproductive o...
