A new study suggests women who become pregnant using in-vitro fertilization appear to have a slightly higher risk of severe birth-related complications. Complications include post-partum bleeding, admission to an intensive care unit, infection of the reproductive system, and — in extremely rare cases — death. The study found that roughly 31 of every 1,000 women who received a fertility treatment experienced a severe complication, compared to about 22 per 1,000 who conceived naturally. Dr. Natalie Dayan says women at risk of IVF-related complications should be monitored closely during pregnancy. But she notes for the vast majority of women who cannot conceive naturally, IVF is a very safe, effective method of having a baby.
