%X Background: Constitutional delay of growth and puberty (CDGP) can cause significant psychological distress in adolescent boys. Although testosterone usage in this group has not been shown to affect the final adult height, the effect on the first year height velocity has not been widely reported.
%X Objectives: The aim is to determine whether testosterone treatment improves the first year height velocity in boys with CDGP when compared to boys with CDGP who go through puberty spontaneously
%X Methods: Retrospective data from 23 adolescent boys with CDGP was analysed. Ten out of 23 boys (43%) received testosterone injection (testosterone enanthate, 125 mg), once every 6 weeks for 3 doses in total. Both the groups (treated and untreated) had their height, bone age and testicular volume measured at the baseline, The height velocity and final predicted adult height were compared at the end of one year between both the groups.
%X Results: In the testosterone-untreated group, the mean (± SD) chronological age, bone age, height standard deviation scores (SDS) and testicular volume were 14.3 years (± 0.3),12.1 years (± 1.6), -1.9 (± 0.8) and 4.7 mL (± 1.1) respectively. Within the testosterone-treated group the mean (± SD) chronological age, bone age, height SDS and testicular volume at presentation were 14.4 years (± 0.4), 11 years (± 1.6), -2.1 SD(± 0.6) and 4.5 mL (± 1.2) respectively. The mean age of treatment with testosterone was 14.4 years (± 0.44). The mean height velocity one year after treatment was 8.4 cm/year (± 1.7) in the testosterone treated group when compared to 6.1 cm/year (± 2.1) in the patients who did not receive treatment (P = 0.01). There was no significant difference in the final predicted height between the 2 groups (P = 0.15).
%X Conclusions: Testosterone therapy improves the first year height velocity in boys with CDGP, without influencing their final predicted height.
