Academic Bio

Dr Hammoud is interested in the public health aspect of infertility. His current and previous research investigates the effects of obesity and environmental pollution on human reproduction. In particular, he is interested in studying the effect of pollution, obesity and weight loss on the male reproductive potential, including sexual function and sperm parameters. He also studies the environmental, genetic and familial factors of Mullerian anomalies of the uterus.
