There has been research for implants and the like for women who were not fertile for various sorts of genetic reasons. The last attempt, that I am aware of, a few years ago did not work and at the time the question of male pregnancy came up. The researchers were not even considering that angle and dismissed it as something that, as of this time, was not feasible for various reasons.
Implanting into a TS woman has been tried before, many decades ago, and it tragically failed.
