Objective: To study the effect of double cryopreservation on the potentiality of the blastocyst in terms of implantation, pregnancy, and perinatal outcomes.
Methods: This study was designed with retrospective data from September 2016 to August 2021 where 39 patients (60 embryos) attempting recryopreserved blastocyst transfer. Endometrial preparation was done solely by hormone replacement therapy (HRT), and any other forms of endometrial preparations were excluded.
Results: Our study found that the implantation rate was 88% and the pregnancy rate was 43.5%, overall wherein 64% were singleton pregnancy rate and 23% were twin pregnancy rate. Perinatal outcomes revealed gestational age, birth weight, and number of ventilation days of the neonates.
Conclusion: Our study concluded that it is advisable to do recryopreservation and embryo transfer (ET) in optimal conditions rather than to waste the embryos by transferring them under trivial conditions.
