Jacques Cohen
Jacques Cohen (born December 26, 1951) is a Dutch embryologist based in New York. He is a Director at Reprogenetics LLC,[1][2] Laboratory Director at ART Institute of Washington at Walter Reed National Military Medical Center[3] (a joint fertility program with NIH), and Scientific Director of R & D at IVF-online.[citation needed] While working with Robert G. Edwards at Bourn Hall Clinic, Cambridge, Cohen reported results in the freezing and successful thawing of a human blastocyst for in vitro fertilization.[4] At the same clinic, he developed methods to treat male factor infertility using in vitro fertilization (IVF) and co-cultured human embryos with helper cells to promote growth.[5] Cohen has been involved in research on the application of micromanipulation techniques to operate on eggs, sperm and embryos. He has (co-)published papers on Intracytoplasmic Sperm Injection (ICSI)[6] and Assisted Hatching.[7] As of October 2024, he is listed as an Emeritus Chief Editor at Reproductive Biomedicine Online.[8] He has also held faculty positions at Emory University, Cornell University Medical College, and the University of Connecticut.[citation needed] Early Career and educationCohen was born in The Hague, Netherlands. In 1970, he went to the State University of Leiden, where he received a BSc degree in Biochemistry and subsequently an MSc degree in Reproductive physiology in 1978.[9] He attended the Erasmus University Rotterdam, where he obtained a PhD degree in Medicine in 1982, for his thesis "Interaction between human spermatozoa and hamster oocytes".[10] EmbryologyIn 1982, Cohen joined Bourn Hall Clinic as an embryologist, working with Patrick Steptoe and Robert G. Edwards on techniques to improve human conception through in vitro fertilization (IVF). Robert G. Edwards was the recipient of the Nobel Prize for Medicine and Physiology in 2010. It was in Cambridge that Cohen first successfully froze and thawed a human blastocyst for use in IVF.[11] Cohen also pioneered the use of micromanipulation techniques now widespread among embryologists. He developed a precursor technique of Intracytoplasmic Sperm Injection (ICSI), now used for the treatment of nearly all male factor infertility diagnoses. Assisted Hatching (AH) is another commonly applied technique aimed at increasing implantation rates among infertile couples. Some of his work, such as cytoplasmic transfer, an attempt to boost development using the cytoplasm of donor eggs to supplement eggs from certain infertility patients, and single sperm freezing, has caused considerable ethical debate.[12] References
