Objective: To evaluate the available evidence to assess cryopreservation of all embryos or subsequent frozen embryo transfer (FET) results compared with fresh embryo transfer.
Design: Systematic review and pregnancy outcome ratio.
Setup: Virk Fertility Services Jalandhar, Punjab. IVF lab for reproductive care. Patient(s): Infertility patient(s).
Intervention(s): We included randomized clinical trials comparing outcomes of IVF cycles between fresh and frozen embryo transfers for almost 422 patients.
Main Outcome Measure(s): The outcomes of interest were ongoing pregnancy rate, clinical pregnancy rate.
Result(s): We included three trials accounting for 422 cycles in women aged 20–45 years. Data analysis showed that FET resulted in significantly higher ongoing pregnancy rates and clinical pregnancy rates.
Conclusion(s): Our results of 422 patients showed that frozen embryo transfer can give better pregnancy outcome in 31-45 age group patient. Because by FET we can maintain time gap between the endometrium and embryos transfer. And we can overcome the adverse effects of controlled ovarian hyper-stimulation (COH) on ER during ART cycles.
