The Jolie-Pitts refuted reports that they used fertility drugs to get pregnant with their new twins. We started wondering -- how common is it to have twins without drugs when parents have no family history of multiples?
|Angelina Jolie told Hello! magazine, "If they had been conceived through IVF, we would have been happy to discuss it ... But we have been fortunate never to have had fertility problems." It seems like Hollywood is twin crazy these days -- even Lisa Marie Presley announced that she is having two little bundles -- and there has been no mention of IVF.
We called friend of momlogic and OB/GYN Suzanne Gilberg-Lenz for her perspective:
"The chance of twins varies on your race, nationality, etc. In the U.S., twins of any kind happen in approximately 12 in every 1,000 births. Two out of every three of
|those births are fraternal. Identical twins occur in 4 of every 1,000 births.|
"Twinning increases with the age of the mom -- 3/1,000 under 20 years old and 14/1,000 for women ages 35 - 40. Fertility medication can increase the chance of twinning, and some studies have shown that 22 percent of all IVF pregnancies are twins -- and these are older studies.
"The rate of twin births has gone up 65% since 1980, largely because the use of fertility treatments is more common. Women who don't use fertility treatments have a 1 in 89 chance of having twins.
"So, do the math -- these twins could be spontaneous or not. I'm sure we will ever know and I wouldn't hazard to guess."
