Sperm DNA fragmentation

It is an honour to write the foreword to this focused issue of TAU on sperm DNA fragmentation (SDF). From my time as a first generation embryologist in the early days at the University of Cambridge with Professor Robert Edwards and in my current role at the London Women’s Clinic, I have become acutely aware of the number of practicalities that still need to be solved in the field of IVF and assisted reproduction. Whilst gene technology and ability to perform mitochondrial transfer are the latest advances applied to early embryos, there are other significant developments, much closer to home, that can influence more people to achieve their goal of achieving a healthy family.
