Oogenesis and early embryology

The Hartshorne group studies oocyte formation (oogenesis) and embryo growth (embryogenesis) with a view to gaining a deeper understanding of human reproduction and development. Our work is closely linked with assisted conception and we aim to promote improvements in clinical treatments in reproduction, particularly the alleviation of infertility. We also explore the social dimensions of our work through research. All our research is approved and licensed under UK regulations.

The group spans the Clinical Sciences Research Laboratories, University of Warwick and the Centre for Reproductive Medicine CRM. Both labs are located on the University Hospital site, Walsgrave, Coventry, CV2 2DX, UK.
