Vascularization
Vascularization was the biological process of increasing the vascular blood flow to a part of the body.

Due to a short pregnancy, Bajoran women vascularized quickly. In 2372, Doctor Julian Bashir cited this fact to explain that he could not transfer Keiko O'Brien's baby back into her womb from Kira Nerys's, where he had transplanted the child, as it would put both Kira and the baby's lives at risk.
