Laboratory & Research


Our state-of-the-art laboratory is one of the primary reasons that RMANJ can boast such high IVF success rates. The RMANJ laboratory is always being updated to reflect the latest technological advancements and is closed down biannually for comprehensive quality control inspections to ensure that our facilities are meeting the highest global standards.

Over the years, our laboratory has led the industry in important advancements such as preimplantation genetic diagnosis (PGD) and extended embryo culture. Our team of experts are working every day to innovate and improve our practice.
