Evaluation of Fertility Success Rate with Simultaneous Transfer of Embryos with Different Qualities in IVF/ICSI Candidates
One of the most important factors in the success of assisted reproductive techniques is the quality of the embryo generated in the laboratory. Whether to transfer only one high-quality embryo or a combination of high- and low-quality embryos is a dilemma.
The present study reviewed the embryo transfer records of IVF/intra cytoplasmic sperm injection (ICSI) patients in Dezful Infertility Center, Iran, to evaluate the impact of the simultaneous transfer of a low-quality embryo on the growth and implantation of a high-quality embryo and live birth.
This cross-sectional study evaluated the files and records of 802 patients undergoing IVF/ICSI at Dezful Infertility Treatment Center from 2013 to September 2020. The patients were classified into group 1: Patients with the transfer of only one grade A (equal blastomeres without fragmentation) embryo, group 2: Patients with the transfer of two grade A and B (equal blastomeres with slight fragmentation) embryos, group 3: Patients with the transfer of two grade A and C (unequal blastomeres with or without fragmentation) embryos, and group 4: Patients with the transfer of two grade C and B embryos.
The mean age of women and men was 32.52 ± 5.10 and 37.59 ± 6.60 years, respectively. Age, duration of infertility, cause of infertility, endometrial diameter, estradiol level, oocyte number, and embryo number had no significant differences between the groups (P> 0.05). Also, the findings indicated no significant differences between the groups in terms of implantation rate, live birth rate, fertility rate, multiple pregnancies rate, and chemical and clinical abortions (P > 0.05).
It seems that the simultaneous transfer of embryos with different qualities does not affect the success rateandfertility outcomes in IVF/ICSI candidates.
