Fewer complications in IVF pregnancies?

New research suggests IVF pregnancies could have lower rates of some complications

Surprisingly, some complications might actually be less common in pregnancies that result from assisted reproductive technology such as IVF

This seems to go against what fertility doctors, obgyns and midwives have been telling their patients for years, namely that women with IVF pregnancies are more likely than "regular" pregnancies to experience pregnancy complications.

What complications were actually less common in IVF pregnancies?

A group looking at IVF outcome data submitted through the Society for Assisted Reproductive Technology (SART) to the Centers for Disease Control (CDC) found that risk of perinatal mortality (the risk of stillbirth or newborn death) in very premature births was lower in women who conceived with IVF than those who did not. They found this to be true with both single births and multiple births (twins triplets, etc.) This informations was recently presented at the American College of Obstetricians and Gynecologists.

Does this mean getting pregnant with IVF is actually safer than getting pregnant on your own?

Probably not. Women who conceived with IVF were less likely to lose a premature baby than those who got pregnant on their own. We have no idea why this is the case. It could be due to more careful prenatal care with IVF pregnancies, or a higher socioeconomic level in couples doing IVF, rather that a results of what is actually going on with the pregnancy. 

Why is this surprising?

There are many studies show a higher rate of complications in pregnancies that result from assisted reproduction such as IVF, and some others that show no effect. It was surprising to find out from such as large database, that at least one serious complication was less common.

Is the traffic outside affecting your chances of having a baby?

Women who live in high traffic areas are more likely to miscarry

Living in a high traffic area may hurt your chances for success with IVF

Research from Harvard presented at the annual meeting of the American Society for Reproductive Medicine suggests that women with a higher exposure to automotive traffic have lower IVF success rates than other women.

The researchers looked at 660 IVF cycles done over a 14 year period and compared their success rates to  how far they lived from a class A roadway. A class A roadway means an interstate, state or US highway. 

Women who lived more than a kilometer (0.6 miles) from a major roadway were 70% more likely to have a baby than those who lived within 200 meters (about 2 football fields) of a major roadway.

Interestingly, both groups of patients had similar pregnancy rates, but the those who live closed to the highway were more likely to miscarry.

Does this mean moving to a low traffic area will improve your chances  of having a baby?

Not necessarily. It does show what we already know, that the environment we live in and the air we breathe plays a role in reproduction, as it does in other aspects of health.
