Scientific Director

Dr Liow Swee Lian has helped many couples achieve their dream of having a baby, and has enjoyed high success rates in the first cycle with frozen embryos

“I am passionate about helping couples who have difficulties in conceiving, and helping them to fulfill their desire to have a family.”

If you are undergoing IVF treatment with Virtus Fertility Centre Singapore, Dr Liow will be closely involved in your treatment programme from the very beginning. As our Scientific Director, he works closely with our fertility specialists and says it is beneficial to meet with patients and help to counsel them through the process.

Dr Liow joined the Department of Obstetrics and Gynaecology at the National University of Singapore in 1990, where he worked with a pioneering group of reproductive biologists and clinical embryologists in Singapore.

Over the past two decades he has helped many couples achieve their dream of having a baby with a high success rate in the first cycle with frozen embryos.

Working with Virtus Fertility Centre Singapore gives Dr Liow access to the latest technology and assisted reproductive techniques, including ICSI and blastocyst culture. He believes the Virtus laboratory is the best IVF facility in South-East Asia, and that he and his skilled team will continue to break new ground in fertility treatment in the region.

  • Assisted egg activation research to identify a chemical-based activating agent that can effectively assist in the activation process.
  • MSc thesis on laser micromanipulation of mammalian embryos, where laser is used to assist hatching – this is now considered faster and safer. Laser is also now used to extract a cell or cells from the egg for genetic diagnosis.
  • PhD thesis was the first study conducted in a multi-ethnic Asian population on microdeletions of genes responsible for sperm production in the DAZ region of the Y chromosome.
  • Currently, Dr Liow is also collaborating with research scientists from Genome Institute of Singapore (GIS). He has published 54 research papers and abstracts, and six chapters in research publications.
