Dr Balaji spent 17 years as the Chief Embryologist at the KKIVF Centre, where he managed the IVF and Andrology labs as well as the National Sperm Bank of Singapore. While there, he performed more than 3,000 intracytoplasmic sperm injections with a clinical pregnancy rate of 40 per cent of embryos transferred.

Dr Balaji has trained many doctors and embryologists on IVF lab techniques,  and was instrumental in achieving Singapore’s first pregnancy and live birth via Laser Assisted Hatching. His more recent achievement was the world’s first live birth from frozen-thawed embryos obtained after in-vitro maturation (IVM) in the lab and intracytoplasmic sperm injections of oocytes recovered from a surgically removed cancerous ovary.
