Dr S. Repping (1974) has been named Professor of Human Reproductive Biology at the University of Amsterdam's Faculty of Medicine (AMC-UvA).
Sjoerd Repping conducts fundamental and translational research in the area of human reproduction. The study is designed to gain insight into the first few cell divisions of the human pre-implantation embryo and the development of spermatozoa from spermatogonial stem cells. The general purpose of the study is to improve healthcare for people with fertility problems by finding the most effective and safe treatment methods in a laboratory setting and developing new techniques. In his capacity as head of the Fertility Laboratory of the AMC's Centre for Reproductive Medicine, Repping contributed to several recent developments in reproductive medicine in the Netherlands, such as eliminating HIV from the sperm of HIV-infected men, extracting spermatozoa from the testes of infertile men (TESE), the genetic screening of human embryos (PGS) and the vitrification of ova.
Repping is principal investigator at the AMC's Obstetrics/Gynaecology department and serves on the board of the Association for Clinical Embryology (KLEM) and the European Society for Human Reproduction and Embryology (ESHRA). In 2008, Repping received a VIDI grant from the Netherlands Organisation for Scientific Research in support of his research on the development of a stem cell in the testis to a fully developed spermatozoon. Four years ago, he received a VIDI grant to study how errors in the Y chromosome can result in poor quality sperm and infertility. Repping has published articles in various leading international scientific periodicals such as Nature Genetics, Cell, NEJM and JAMA.
