Test can predict success of IVF: U.S. report
U.S. researchers have developed a formula that can predict whether fertility treatment will succeed more accurately than using age alone, and used it to develop a commercial test.
They said their test, published in the Proceedings of the National Academy of Sciences on Monday, could save couples the agony and expense of multiple attempts to have babies using in vitro fertilization, also known as IVF.
A team lead by Dr. Mylene Yao of Stanford University in California, decided to look at dozens of factors, including age but also looking at how well and how fast the embryos grow, a woman's hormonal response to the treatment and the condition of her uterus when the embryo is implanted.
They used data from more than 5,000 IVF cycles performed at Stanford Hospital from 2003 to 2008 and matched it to success rates.
