Thank you for your question. While a tummy tuck (TT) can help contour the abdominal area by removing excess skin and fat, it is unlikely to significantly impact your penis size. Some plastic surgeons may perform procedures that involve releasing the check rein ligaments of the penis or removing excess fat around the base of the penis, which can slightly enhance the appearance of length. However, these procedures typically do not result in a substantial increase in actual penis size. Given your concern about having a micropenis and hypogonadism, it would be beneficial to consult with a urologist who specializes in male sexual health. A urologist may offer additional options or procedures that could better address your concerns about penis size, such as hormone therapy or surgical interventions specific to penile enhancement. I hope this helps provide clarity, and I encourage you to seek a specialist for more targeted advice. Sincerely, Dr. Katzen
