Horacio
CROXATTO MD. Professor,
Faculty of Biological Sciences
and Faculty of Medicine, Pontificia Universidad Católica
de Chile. Presidential Chair in Science.
Professor Horacio Croxatto had
his research training in Neuroendocrinology with Professor
Charles Sawyer, University of California in Los Angeles and
then in Reproductive Endocrinology with Professor Sheldon
Segal at Rockefeller University. The focus of his
basic research has been on the physiology of gamete
and embryo transport in the female genital tract of mammals.
Using rodents, he established that egg transport through the
oviduct occurs neither at random nor with an invariable determinism,
but is subject to physiologic regulation. He
organized a research training program in reproductive biology,
addressed to young Latin American scientists which was funded
by the Rockefeller Foundation for five consecutive triennia
since 1980. He has served in a number of international committees
concerned with reproductive sciences, including WHO/Human
Reproduction Program, the International Committee for Contraception
Research of the Population Council, The Program for Appropriate
Technology for Health (PATH) and the Committee on Applications
of Biotechnology to Contraceptive Research & Development
of the Institute of Medicine, National Academy of Sciences,
U.S.A. and the Latinamerican Association of Reserchers in
Human Reproduction (ALIRH). He was nominated member of the
Latin American Academy of Sciences. He founded the Chilean
Institute for Reproductive Medicine, a private not for profit
organization devoted to research, service and education oriented
to promote reproductive health. Dr. Croxatto is a recipient
of a Presidential Chair Award from the Chilean Government.
