Table 1. Possible effects of adipokines adiponectin, resistin and leptin on insulin sensitivity and ovulation.
Hormone	Circulating levels in obese	Primary effects	Effect on insulin sensitivity	Possible effect on ovulation
Adiponectin	Decreased	Increases fat oxidation and insulin sensitivity	Increased	Enhanced ovulation
Leptin	Increased	Integrative signal of energy stores, anorexic	Increased	Adverse ovulation
Resistin	Increased	Increases insulin resistance	Decreased	Adverse ovulation
