Optimizing IVF Success: A Case Study of Melatonin-Assisted Frozen Embryo Transfer for Poor Oocyte Quality and Endometriosis.

The case study investigates the journey of a couple facing infertility. It intensifies the challenges, including poor oocyte quality and endometriosis. In spite of two failed fertilization cycles, the decision for ovum pickup (OPU) was made, followed by intra-cytoplasmic sperm injection (ICSI), embryo treatment with melatonin, and frozen embryo transfer (FET) to optimize the chances of a successful pregnancy. The couple opted for this approach. OPU yielded four poor-quality oocytes, prompting ICSI and melatonin treatment to enhance embryo quality. The embryos were exposed to culture supplementation with melatonin for 72 hours before being transferred to conventional media. After 5 days or 120 hours, the embryos developed into 3BB quality blastocysts, indicative of developmental stage and morphology. The blastocysts were then cryopreserved, and after 2 months, FET was conducted, resulting in the transfer of two embryos, which subsequently led to a positive pregnancy indication, as indicated by a β-hCG level of 233 mUI/ml measured 14 days post transfer. This approach highlights the effectiveness of melatonin supplementation in improving embryo quality and ultimately facilitating successful pregnancy in complex scenarios like endometriosis-related infertility.
