Delayed puberty can cause short stature, emotional distress, and social challenges. Testosterone therapy promotes growth and masculinization, but its impact on quality of life remains poorly understood. Few studies have assessed psychosocial outcomes using validated instruments.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"j_jpem-2025-0719_abs_003\">\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Twenty-seven boys enrolled in the Pubertal Replacement in Boys Study and were randomized to testosterone enanthate (75\u202fmg\/month for 6\u00a0months; n=12) (n=12) or testosterone undecanoate (n=12) (250\u202fmg every 3\u00a0months; n=15). Standardized self-report questionnaires assessed generic quality of life (primary outcome), stature-specific quality of life, depressive symptoms, and enjoyment of physical activity. Assessments were conducted at baseline, 6\u00a0months, and 12\u00a0months.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"j_jpem-2025-0719_abs_004\">\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Twenty-six boys completed the study. Both regimens induced pubertal progression and a mean growth of 9.3\u202fcm 12\u00a0months after start of replacement treatment. Significant improvements were observed in generic quality of life and depressive symptoms, with early gains sustained through 12\u00a0months. No changes were detected in stature-specific quality of life or enjoyment of physical activity. No statistical differences were found between treatment groups at 6 or 12\u00a0months. Exploratory analyses suggested that baseline testosterone serum levels were modestly associated with changes in social functioning, whereas later serum levels showed no such relationship.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"j_jpem-2025-0719_abs_005\">\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Low-dose testosterone therapy improves generic quality of life and mood in boys with self-limited delayed puberty, likely reflecting successful pubertal progression.
