This study is to evaluate the efficacy and safety of aromatase inhibitors (AIs) in the treatment of short stature in male children and adolescents. Pooled estimates of final or near-final height, predicted adult height (PAH), bone age, and potential side effects were calculated using a random-effects model or fixed-effects model. Our search identified 11 studies with a total of 463 participants. AI was associated with a significant increase in final or near-final height (weight mean difference (WMD)=3.61 cm, 95 % CI: 0.96, 6.26; p<0.001) and PAH (WMD=2.52 cm, 95 % CI: 0.32, 4.72; p=0.025) compared to other treatment. The use of AI showed an increased risk of minor side effects (risk ratio (RR)=2.90, 95 % CI: 1.15, 7.33; p=0.025), but no severe adverse effects were reported. Subgroup analysis, stratified by patient disease, revealed that AI significantly enhanced final or near-final height in both patients with idiopathic short stature (ISS) and those with constitutional delay of growth and puberty (CDGP). AIs may contribute to height increase in male children and adolescents with short stature, without significantly advancing bone age. However, the increased risk of minor side effects indicates the need for careful monitoring during AI therapy.
