The Frisco Institute for Reproductive Medicine is one of a very few programs in the United States (indeed, in the world) that offer single blastocyst transfers. This can only be achieved with a superior in vitro fertilization laboratory that can support the growth of blastocysts well enough to compete with pregnancy rates obtained when transferring two or more embryos. Even though the first successful birth after IVF in 1978 was the result of transferring a single eight-cell embryo, the transfer of single embryos is rarely practiced in the United States. In contrast, the government-mandated transfer of a single, cleavage-stage embryo is common in much of Europe, with emphasis on the cumulative fresh-frozen cycle outcome.
It is perceived by many that risks associated with twin gestations (also see: Complications and Problems with Multiple Births from ASRM) are readily manageable. Expenses related to the medical care of a mother carrying two babies are routinely covered by insurance. The expenses for repeat IVF cycles following a failed attempt or to have a second child must be dealt with by the couple. The above are surely legitimate concerns but outweighed by the need to minimize maternal and infant jeopardy.
