@goatsarah It's possible to genetically modify gonads IN ADULTS so they produce desired levels of T or O. It's not even that difficult (for trans men, it would involve a one-off tamoxifen injection directly into the ovaries). As soon as the trans community figures out how to use genetic engineering, governments will find it nearly impossible to stop us: https://onlinelibrary.wiley.com/doi/10.1002/bies.200900193
