This person doesn't seem to understand how pregnancies, particularly unwanted ones, occur. And he is clearly clueless about the complex series of tasks a woman's body must undertake, and succeed at, in order to get and stay pregnant. All these TRAs think the uterus is an easy-bake oven; they have no idea about all the complicated, myriad functions a woman's body has to perform to sustain a pregnancy from the get-go.

Even if it ever were to become possible for TIMs to get uterus transplants, a TIM still could not pregnant by natural means. He could try to have an IVF embryo from a donor egg implanted into the borrowed uterus - though that probably wouldn't be possible through a surgically-created fauxgina since those are by definition dead-ended.

Also, since a TIM wouldn't have female DNA or biochemistry, there's no way the IVF embryo would successfully be implanted into the uterine lining. And since a male body doesn't have the genetic code to instruct it to begin producing the cells and hormones that will cause a woman to begin growing a placenta, an embryo implanted in the endometrium of a uterus put in a male body would not receive adequate blood supply, nutrients, antibodies etc to remain viable.

In other words, a uterus placed in the body of a man wouldn't be able to sustain embryonic life long enough for an abortion to be required. The embryo would die on its own.
