A study by Sir et al suggested that gynecomastia can impinge on male sexual function. The study, which included 47 patients and 30 healthy controls, found that, as evaluated with the International Index of Erectile Function (IIEF), scores for erectile function, orgasmic function, and intercourse satisfaction were significantly lower in patients with gynecomastia than in the control group. However, the gynecomastia patients had a significantly higher mean IIEF desire score than did the controls. The study also found that hormone profiles (serum free triiodothyronine [T3], free thyroxine [T4], thyroid-stimulating hormone [TSH], follicle-stimulating hormone [FSH], prolactin, estradiol, total testosterone, free testosterone, luteinizing hormone, and dehydroepiandrosterone sulfate [DHEA-SO4]) for the gynecomastia patients were similar to those of the controls, with the exception of FSH and free T3, which were significantly lower.
