In-vitro Fertilisation (IVF) is a fertility treatment which involves stimulating of the ovaries to produce a good number of eggs. Unfortunately, the process of stimulating the ovaries may disrupt the endometrium and could impact negatively on the implantation and pregnancy rate, if the embryos are transferred within days after Oocyte Pick-Up (OPU) [1].
In order to circumvent this problem, elective frozen embryo transfer (FET) has gained popularity for several years now. This involves freezing the embryos (also known as embryo cryopreservation), which is then later thawed and transferred into the uterus with minimal or no hormonal intervention. Studies have reported evidences supporting elective FET in reducing the risk of ovarian hyperstimulation (OHSS) and achieving higher pregnancy rate [2].
