Paul Devroey is a Belgian researcher and professor specialized in human fertility. He works in the university hospital of the Vrije Universiteit Brussel, where he directs the Center for Reproductive Medicine. Together with André Van Steirteghem and other colleagues from the Center he developed the Intracytoplasmic Sperm Injection (ICSI) technique, in which a single sperm is injected into an egg-cell. This technique is particularly useful in cases where infertility is caused by poor sperm production, thus solving most problems of male infertility. His center also pioneered various other techniques that increase the chances of successful in vitro fertilization, such as preimplantation genetic diagnosis.
Paul Devroey (co-)authored over 440 international peer reviewed articles, some of which have over 1000 citations, and three books. Over his career, he has received three national and four internationals research awards, including the IVI award 2007.
