Alexia Chatziparasidou

Sr. Clinical Embryologist, M.Sc.

Alexia Chatziparasidou is a senior clinical embryologist with experience of more than 45,000 IVF cycles. Her scientific interest is mainly focused on the application of modern oocyte and embryo cryopreservation methods and treating male infertility and azoospermia, as well as on developing methods of co-culture with homologous endometrial cells.

She graduated from the Biology Department of the Aristotle University of Thessaloniki (AUTH). After completing postgraduate studies with distinction in 2006 (Clinical Embryology with Honours at the University of Leeds, UK), she was actively involved in preimplantation genetic diagnosis and counselling of infertile couples.

In 2004, Ms Chatziparasidou founded Embryolab, a modern assisted reproduction unit, which she also directs. She is a member of the International Society of Reproductive Scientists, (ALPHA), the European Society of Human Reproduction (ESHRE) and the American Society of Reproductive Medicine (ASRM).

She is involved in a variety of international partnerships, such as with an Italian IVF unit on the cryopreservation of oocytes, an IVF unit in Tokyo, Japan on new embryo and oocyte cryopreservation techniques, with the university IVF unit of Montreal, Canada on new techniques in-vitro matured oocytes, and with a German IVF unit on methods and techniques to preserve female fertility.

Ms Chatziparasidou is co-founder and co-director of the Embryolab Academy, an international research and educational non-profit organisation.
