Freezing and subsequent transfer of embryos gives infertile couples just as much of a chance of having a child as using fresh embryos for in vitro fertilization (IVF), research from Ho Chi Minh City, Vietnam, and Adelaide, Australia has found.
In results to be published in The New England Journal of Medicine, the research team shows that ongoing pregnancy rates and live births were equivalent in a group of IVF women implanted with frozen embryos compared with fresh embryos.
New research indicates that pregnant women with pre-gestational diabetes who take metformin are at a higher risk for adverse pregnancy outcomes—such as major birth defects and pregnancy loss—than the general population, but their increased risk is not due to metformin but diabetes.
Prematurity is the main complication of pregnancy, and 15 million babies are born preterm worldwide each year. Physicians worldwide have investigated whether vaginal progesterone administration to women with a mid-trimester sonographic short cervix reduces the rate of preterm birth. Now physicians and researchers have found that when all available information is considered in an individual patient data meta-analysis, the results are clear: vaginal progesterone reduces the rate of preterm birth at <28, <30, <32, <34, <35, and <36 weeks.
A new analysis of published studies found an approximate 80% increased risk of spontaneous preterm birth (both before 37 and 34 weeks) when women become pregnant via in vitro fertilization (IVF) than through spontaneous conception. The Ultrasound in Obstetrics and Gynecology analysis included 15 studies with approximately 62,000 patients and about 3800 preterm births events.
Women who became first-time mothers as teens were significantly more likely than older mothers to have greater risks for heart and blood vessel disease later in life, according to new research in Journal of the American Heart Association.
A new study reveals that due to a lack of specific recommendations for medication use during pregnancy, many pregnant women search the Internet for information.
