Physical, metabolic, and hormonal effects on men of long-term therapy with medroxyprogesterone acetate.
Twenty-three men were treated with injectable medroxyprogesterone acetate (MPA) for sex-offending behavior. The physical, hormonal, and metabolic effects were monitored. The patients had significant (P less than 0.001) weight gain and increases (P less than 0.0001) in systolic blood pressure independent of weight gain. MPA therapy decreased testosterone (P less than 0.0001), luteinizing hormone (P less than 0.005), and testicular size (P less than 0.001), but not follicle-stimulating hormone. MPA's suppression of total sperm count was not consistent, but MPA significantly reduced sperm motility (P less than 0.001) and percent normal morphology (P less than 0.005). Statistically insignificant increases in insulin response without changes in glucose tolerance occurred in all patients, but only one patient developed overt diabetes mellitus. Three men developed gallstones, but none had significant changes in liver function. Patients receiving high-dose MPA therapy should be carefully monitored for blood pressure changes, diabetes mellitus, and gallbladder dysfunction.
