Dr Helen O'Neill: The woman who is changing what we know about hormones

Season 8, Ep. 4

Dr Helen O'Neill is many things: a mirror twin, an associate professor in reproductive and molecular genetics at UCL, and also the co-founder and chief executive of Hertility, the at-home hormone testing company which is changing what we know about infertility: the company has built up a database of 700,000 people whose responses to its health survey may shed new light on its causes. Meanwhile, O'Neill's research is giving us new information about why, for example, male embryos develop slightly faster than female embryos.


Meanwhile, Emma Whitney, director of embryology and genetics at The Evewell, explains PGT-A to us. Is it worth it?
