Should females who transition into men have children?

I'm not against transitioning all together!But when someone already started hormones and transitions I think it's selfish these people decide to have children, I think the hormones could harm the baby. It's sad to see Britain's first pregnant man. Okay if you decided to be a man, please stop attention seeking or trying to break records that are put of norm. I think people have the right to be transgender even if they had a child previous to the transition but once the transition takes place embrace your new role!
