Dr. Jayasena co-chaired the 2021 Society for Endocrinology Guidelines for Testosterone Treatment in men Click for article
Dr. Jayasena leads the NIHR Health Technology Assessment Testosterone Efficacy & Safety (TestES) Consortium of researchers in 17 countries. TestES has provided the most comprehensive study to date on risks of cardiovascular events during testosterone treatment in men with low testosterone. Click for article
He has also conducted work revealing that partners of women with recurrent miscarriage have a high risk of sperm DNA damage and reactive oxidative stress Click for news feed
Dr. Jayasena's team is one of the few international centres with expertise in fertility treatment for men with azoospermia. They has developed cutting edge techniques such as seminal reactive oxygen species (ROS) measurement, microsurgical testicular sperm extraction (mTESE) and testicular mapping.
