Reduction is the removal of one of the implanted embryos at an early stage of pregnancy. Why do that? The chances of multifetal pregnancy resulting from artificial insemination are much higher than the chances of multifetal pregnancy achieved by natural conception. Usually, more than one embryo is transferred into the uterine cavity. And yes, theoretically they all can implant. Then the decision of whether to leave everything as it is or to remove the weaker embryo so that the stronger one can grow healthily is made. This procedure has both moral, ethical, and medical aspects. We will talk about them today with the Biotexcom clinic Ph.D., Olena Mozhova.
