AOPA PPS is helpful for most medical issues, but when it comes to transgender pilots they are not very knowledgeable and are unable to assist or speed up the process. We do not recommend AOPA PPS for assisting transgender pilots.
AMAS provides aviation medical services to companies and individuals. Many aviation employers contract AMAS for assisting their pilots in the medical process. If your employer does not contract with them, you can hire them to assist you with the process. They are very knowledgeable in the process and can help move things along more quickly. Its about $100 for a consultation, and $1000+ to have them take your case to the FAA for faster resolution.
