title: Aromatase Inhibitors in the Treatment of Short Stature.
abstract: Reports published in the 1990s of men with estrogen deficiency caused by defective aromatase or estrogen resistance due to a defective estrogen receptor α confirmed the crucial role of estrogen in bone maturation, closure of the epiphyses and cessation of statural growth. Based on these findings, it became reasonable to postulate that selective inhibition of estrogen synthesis with aromatase inhibitors could increase adult height by delaying bone maturation and prolonging the period of growth in males. To date, aromatase inhibitors have been employed in rare pediatric conditions associated with sex steroid excess, and in randomized controlled trials involving boys with short stature and/or constitutional delay of puberty. Findings from these randomized trials suggest that potent aromatase inhibitors increase predicted height, but final adult height data are scarce. Moreover, several safety issues remain inadequately studied. In this paper, published findings on the use of aromatase inhibitors in growth indications are reviewed with emphasis on treatment efficacy and safety.
