Began research career at the University of Cambridge where he gained his PhD under the supervision of Professor Robert Edwards. During these early years Dr Fishel, amongst other research work, was the first to demonstrate that the embryo ‘communicates’ with its environment; and, later, was the first to publish on the secretion of HCG by the human embryo. Concomitant with his appointment as a don at Churchill College, Cambridge in 1978, was the award of the prestigious Beit Memorial Foundation Fellowship; and he also became a Cambridge University Lecturer. Subsequently, in 1980, while maintaining his University position, Dr Fishel became Deputy Scientific Director at the opening of the world's first "test tube baby clinic" at Bourn Hall in Cambridge continuing his work with Robert Edwards and Patrick Steptoe. It was at Bourn Hall that Dr Fishel was renowned for his scientific publications of a number of seminal papers on the early work of IVF and human embryology. He had been working with Robert Edwards for a number of years before the birth of the world's first test tube baby, Louise Brown. Dr Fishel is one of the world's most experienced practitioners in the field of Assisted Reproduction Technology/ Assisted Conception, and after more than 30 years, is the “longest-running” practitioner of clinical human embryology/IVF. He has established IVF clinics all over the world, including being part of the first team invited by the W.H.O. to introduce IVF to mainland China. He is regarded as one of the pioneers of in vitro fertilisation technology and specifically the use of micromanipulation techniques for sperm injection and embryo biopsy, and has published over 200 papers and three books in the field, including the early ‘best seller’ In Vitro Fertilisation – Past, Present, Future in 1986.
