What are signs that pubertal gynecomastia is going away? How can I expedite the process?

Confusing question. Pubertal gynecomastia will occur in 1/3 to 1/2 of males ; generally last about a year before fading.Intensity varies from small lump to generous boobs.Overweight kids can appear to have it from just fat accumulation.If present after 3 years, and or weight loss,surgical removal of the glandular tissue ; liposuction of any associated fatty tissue will do the job.
