Channa Jayasena is a Clinical Senior Lecturer and Consultant in Reproductive Endocrinology and Andrology at Imperial College and Hammersmith Hospital, London. Dr. Jayasena qualified in medicine at Cambridge University, after which he undertook specialist training in Diabetes & Endocrinology in London. Having been awarded a Wellcome Trust Clinical Research Training Fellowship and NIHR Clinical Lectureship, he conducted first-to-human studies at Imperial College investigating the clinical effects of novel hypothalamic neuropeptides such as kisspeptin on the human reproductive axis of men and women. He is currently Clinical Lead for Male Infertility / Andrology at Hammersmith Hospital which has developed cutting edge techniques such as seminal reactive oxygen species (ROS) measurement, microsurgical testicular sperm extraction (mTESE) and testicular mapping.

Dr. Jayasena has recently been awarded an NIHR Post-Doctoral Fellowship investigating the metabolic regulation of male infertility. He is also Chief Investigator on an NIHR Health Technology Assessment (HTA) funded project to investigate the Efficacy and Safety of Testosterone Replacement in Men (TestES Consortium).
