Currently theres no solution for it, other than a full penis transplant (a surgery very hard to get).
I'm so sorry you're going through this. Know that you are not alone and there are options available outside of a shaft transplant.
We actually offer a penile repositioning and ligamentolysis surgery specifically designed to correct micropenis. It's called the MicroMAXL and you can read about it towards the bottom of this page on our website: https://www.rejuvall.com/best-enlargement-technique/
I'm happy to answer any questions you may have. Don't despair; there is hope.
