Clinical Team

Our Embryologists & Research Scientists

Our success in the field of assisted reproduction can be attributed in part to our highly trained laboratory personnel. Our laboratory team is a mixture of scientists from technical, research and medical backgrounds educated to a minimum of MSc level, but most to PhD level. In addition, our andrologists and embryologists are deemed competent and certified in their speciality by the European Society of Human Reproduction and Embryology (ESHRE), an internationally recognised laboratory qualification. Our embryologists also participate in the Continuous Embryology Education Credit system managed by ESHRE. The team frequently attend educational and research-based national meetings and international conferences.
