Multiple Factors

Background: Assisted reproductive technology (ART) cycles include in vitro fertilization of the sperm and ovum and transferring the embryo formed into the uterus of the patients. In ART cycles, there is still a shroud of doubt regarding the pregnancy outcomes of embryo transfer on day 3 versus the embryo transfers on day 5 as well the better pregnancy outcome with fresh versus frozen embryo transfer and the number of embryos transferred. This study is aimed to evaluate these factors and study the way to optimize methods to obtain highest pregnancy outcomes.Methods: A retrospective study was performed of 87 patients who had undergone embryo transfers during the duration of the study from an IVF centre in Ahmedabad. Multiple factors were studied and the clinical outcome was tabulated. The pregnancy outcomes were compared using the values of beta- hcg (human chorionic gonadotropin). The data was compiled and analyzed using Google spreadsheets. To find the statistical difference between different factors- the statistical method of Fischer’s exact test and p-value was used.Results: No statistical difference between day 3 and day 5 embryo transfer as well as between frozen and fresh embryo transfer were both. All of them were found equally efficacious, although 3 and 5 number of embryo transfers were found efficacious.Conclusions: In conclusion authors recommend a day 5 embryo transfer with 3 or 5 embryos which are best-quality frozen or fresh embryos to achieve maximum pregnancy outcomes.

Objective To evaluate the performance of an in vitro fertilization (IVF) laboratory using a new set of key performance indicators (KPIs) when the main treatment of IVF patients had been changed. Methods Patients who underwent fresh embryo transfer and the freeze-all strategy in August, September, and October 2017 were retrospectively studied to evaluate the performance of an IVF laboratory in September when implantation rate of fresh embryo transfer decreased. KPIs associated with blastocyst culture and the first frozen embryo transfer (FET) cycle in patients with the freeze-all strategy were compared over 3 months. Results Day 5 usable blastocyst and good quality blastocyst rates, and day 3 usable/good quality embryo rates were not different among the three periods. The implantation rate and KPIs associated with morphological changes in warmed blastocysts in the first FET cycle in patients with the freeze-all strategy were also not different among the periods. Conclusions KPIs associated with embryo quality, blastocyst culture, and the pregnancy outcome of the first FET cycle in patients with the freeze-all strategy suggested that performance was unaffected in our IVF laboratory in September. These KPIs might be useful for internal quality control analysis of IVF laboratories.
