But at St Mungo's, the introduction of Muggle medicine had only just begun. Many wizards, including Ron, who had two friends from the Muggle world, could not accept that sort of "treatment." Then there was the issue of IVF. Wizards faced an even more severe population problem than Muggles, yet wizards led by Dumbledore prohibited the use of this technology among wizards.
