Some IVF Patients Fail to Follow Lifestyle Recommendations

iStockphoto/Thinkstock(BOSTON) -- Women who undergo in vitro fertilization are advised to make several lifestyle changes, but many women do not always take the recommendations to heart, a new study has found.

Most doctors recommend that women stop or cut back on caffeine, alcohol, nicotine and herbs because it decreases their chances of becoming pregnant. Women are even advised to tone down their exercise regimen, as well.

But new research from Boston IVF, an infertility treatment center, examined data from 118 women who underwent an IVF cycle between June 2009 and March 2010 and found that many women were not following recommendations. While it appeared most women were generally living healthier lifestyles than in the five years before their IVF cycles, about half of the study participants reported still drinking one to two alcoholic beverages per week. Three percent reported smoking during their IVF cycle.

Patients at the center are advised to limit caffeine consumption to about 50 milligrams (one soda, one cup of tea) per day, but almost half of the patients reported to continue drinking caffeine each day. Most of those caffeine drinkers reported drinking coffee, which can have anywhere between 60 and 200 milligrams of caffeine in one cup.

And even though patients are told to cut back on exercise, about 12 percent reported exercising at least once a week.

“Something like running can be really jarring and painful during an IVF cycle because the ovaries are enlarged,” said Dr. Alice Domar, the study’s lead author and executive director of the Domar Center for Mind and Body Health of Boston IVF. “While we think going out for a run makes us feel good and feel like we can eat that cupcake later, our bodies take it as we’re running from a bear, which is not conducive to your body if you’re trying to get pregnant.”

While the survey size is too small to make blanket responses and suggestions, Domar said they were surprised by the results because each cycle can cost nearly $20,000, and women really want to get pregnant.

“An IVF cycle is only 28 days, so patients really need to understand that they should maximize their chances of getting pregnant at that time,” Domar said. “If it doesn’t work, then they can go back to their normal lifestyle habits, but they should really capitalize on their chance if they can.”

In IVF, Is Three Embryos Too Many?

iStockphoto/Thinkstock(GLASGOW) -- A new study suggests women undergoing in-vitro fertilization (IVF) should receive no more than two embryos, regardless of their age or the quality of the embryos. But some fertility doctors say the benefits and risks of transferring extra embryos still depend on the woman.

In IVF, a woman’s eggs are fertilized outside of her body and the resulting embryos are transferred into her uterus. Because not all embryos will successfully implant and result in pregnancy, doctors often transfer more than one -- a practice that increases the odds of multiples and, consequently, the risk of complications.

The British study, which was based on a review of more than 120,000 IVF cycles yielding 33,514 live births in the UK, found a higher live birth rate and lower complication rate among women who received two embryos compared with women who received three, regardless of their age. Transferring two embryos was associated with a higher live birth rate than transferring one, and the live birth rate was lower among women over 40, irrespective of the number of embryos transferred.

“In older and younger women, the transfer of two embryos was associated with greatest live birth rates,” the study authors wrote in their report, published Wednesday in The Lancet. “A clear implication of our study is that transfer of three embryos should no longer be supported in women of any age.”

The American Society of Reproductive Medicine and the Society for Assisted Reproductive Technology currently recommend transferring no more than two embryos in women younger than 38, no more than four embryos in women aged 38 to 40, and no more than five embryos in women 41 to 42.
