Medical Groups Recommend the Transfer of Fewer Embryos in Fertility Treatments

Yesterday the American Society of Reproductive Medicine and the Society for Assisted Reproductive Technology released revised guidelines for the number of embryos transferred during assisted reproductive therapies, recommending the transfer of no more than two embryos during a single procedure for women younger than age 35. In 1999, the ASRM had released guidelines recommending the transfer of only two embryos for women younger than age 35 with a “healthy” prognosis and three embryos for women with a poorer prognosis for successful implantation. The recommendation rises to as many as four embryos for patients aged 38 to 40 and to five embryos for women over the ago of 40.

Today more than a third of pregnancies conceived using assisted reproductive technology result in a multiple birth. Multiple embryo transfer has also contributed to what are now more than a half million frozen stored embryos awaiting: future use, “adoption,” stem cell research or, for most, destruction.

Liza Mundy writes about couples facing such decisions and the ways in which the nation’s embryo glut is changing the choice debate in the July/August issue of Mother Jones.

DEMOCRACY DOES NOT EXIST...

without free and fair elections, a vigorous free press, and engaged citizens to reclaim power from those who abuse it.

In this election year unlike any other—against a backdrop of a pandemic, an economic crisis, racial reckoning, and so much daily bluster—Mother Jones' journalism is driven by one simple question: Will America move closer to, or further from, justice and equity in the years to come?
