    [Truncated abstract] This thesis reports on a comprehensive study of the relationships between male age, oxidative stress and fertility within the context of assisted reproductive technology (ART). The central hypothesis was that oxidative stress is a significant mechanism through which advanced paternal age influences fertility. Two approaches encompassing three studies made up the project – a) a cohort study using a sperm donor model (Study 1) and b) a cell biology approach utilising fresh (Study 2) and cryopreserved (Study 3) semen samples. The first approach, (Study 1) aimed to determine the clinical relevance of male age on fertility. The influence of paternal age on clinical pregnancy was investigated using a donor insemination cohort where female recipients had no known fertility problems. Analyses were undertaken separately within 2141 insemination cycles involving younger women (
