Can a female to male transvestite get another female pregnant?

The term "female-to-male transvestite" does not exist because transvestites are cross-dresses. The term that you want is "transsexual." Answering the question with transsexual as the subject, no; a female-to-male transsexual cannot impregnate a female because the transsexual is and always will be female. Apparently, females naturally produce ovum, not sperm. Therefore, she would never be able to produce sperm cells, the very cells that help impregnate females in the first place.
