单词	multifetal
释义	multifetal /ˌməltēˈfētl/ /ˌməltī- / adjective Involving two or more fetuses: multifetal pregnancy... Pressure has mounted to decrease the number of embryos transferred in pregnancy attempts, because multifetal gestations are associated with serious health risks for mothers and children. In high order multiple pregnancies (triplets or greater) multifetal pregnancy reduction confers a clear benefit in terms of perinatal outcome. Finally, although huge efforts are now being made to counteract multifetal pregnancy rates through elective single embryo transfer, the multiple birth epidemic may continue as a result of the wide use of ovulation inducing agents.
