I suggest that you
search these forums for the words "fertility" and "pregnant". You'll find dozens of discussions, including
Pregnancy After BMT? and
Aplastic Anemia and Pregnancy.
The question of fertility often comes up when transplants are being discussed. Sometimes your primary hematologist can give you information, but you almost always need to consult specialists to get the answers you need, such as the options for freezing eggs prior to a transplant.
