More embryos do not lead to better success rates

Haven't we been saying this for a long time?

 

 

A new study of fertility treatment in found that women who get three or more embryos have no better odds of having a baby than those who get just two embryos.

They also have a greater chance of risky multiple births.

“Women who have gone through infertility treatment want

Big surprise: The incidence of twins is up

 

An analysis of three decades of twin births (2009 data are the most recent year included) finds large increases in twin birth rates for all age groups, among all racial and ethnic groups and in the U. S. The overall U.S. twin birth rate increased 76%, from 18.9 in 1980 to 33.2 per 1,000 births in 2009.

Reproductive Partners makes outreach to China

Two Reproductive Partners physicians have been invited to China to present the latest advances in fertility treatment and screening for genetic diseases at a major hospital in Bejing. Drs. Bill Yee and Greg Rosen  are currently lecturing on preimplantation genetic screening, molecular technology to screen for a variety of recessive genetic diseases and criteria for maximizing the success rate

Another factor in selecting single embryo transfer (eSET)

This is one of a series of news items from abstracts of studies presented at the Annual Meeting of the American Society for Reproductive Medicine as complied by Dr. David Meldrum, Scientific Director of Reproductive Partners. We appreciate the enormous amount of work it takes to compile and comment on these abstracts.

Does IVF increase the chance of identical (monozygotic) twins?

It does, at least according to a study in the July 2010 issue of Fertility & Sterility.

The authors surveyed 4976 clinical pregnancies from one large IVF center and found ninety-eight cases of monozygotic twins (MZTs) were diagnosed after first-trimester ultrasound evaluation (2% incidence). In naturally conceived pregnancies the incidence is about 0.25-0.5%. 

The incidence in women transfering embryos from …

RPMG studying financial incentives for eSET

The LA Times article mentioned in the previous post shows the non-signficant difference in success rates between single- and double embryo transfers in a study from Sweden. Most impressive is the reduction in potentially complicated multiple pregnancies by transferring one embryo which should be an incentive for appropriate couples to select this option.

But in most of the U. S.,
