Excess body weight impacts fertility during both natural and assisted reproduction (ART) cycles. In men, the immediate effect is hypoandrogenism through decreased testosterone levels and an increase in peripheral aromatization of androgens to estrogen, although this does not seem to cause significant change in conventional semen parameters. In women, the impact seems to be through various pathways, by both animal and human studies.
