What are the risks of multiple births while taking fertility medications?
When used by fertility experts with careful monitoring of their patients, multiple births with Clomid/Serophene should be 6-8%, hMG 15-20%, and IVF 15-25%. High multiples are always undesirable, and careful monitoring of the woman’s response to medications will minimize this risk unless IVF is used. With IVF, the risk increases with the number of embryos transferred, the quality of the IVF lab, and the use of assisted hatching.
