, leading to further reductions in the percentage of twins and high-order multiple births, according to the latest data on the use of assisted reproductive technologies in the United States. The data come from the Society for Assisted Reproductive Technology's 2010 IVF IVF in vitro fertilization.

The percentage of cycles resulting in live births among women younger than age 35 was 41.7%, compared with 31.9% for those aged 35-37 years, 22.1% for those aged 38-40, 12.5% for those aged 41-42, and 4.1% for those older than age 42. Corresponding live birth rates from the 2003 IVF Success Rate National Summary were 37.5% for women younger than age 35, 30.4% for those aged 35-37, 20.2% for those aged 38-40, IL2% for those aged 41-42, and 4.5% for those older than age 42.

According to the 2010 report, the average number of embryos transferred per cycle was 2.0 for women younger than age 35, 2.2 for those aged 35-37, 2.6 for those aged 38-40, 3.0 for those aged 41-42, and 3.1 for those older than age 42. In 2003, the corresponding average number of embryos transferred per cycle was 2.6 for women younger than age 35 years, 2.9 those aged 35-37, 3.2 for 40, 3.5 for those aged 41-those older than age 42. those aged 38-42, and 3.5 for those older than age 42.

A striking increase in the use of elective single cell embryo transfer (e-SET) has occurred since 2003, when the percentage of cycles with e-SET was only 0.7% for women younger than age 35, 0.4% for those aged 35-37 years, 0,2% for those aged 38-40, 0.1% for those aged 41-42, and 0.0% for those older than age 42. In 2010, the percentage of cycles with e-SET was 9.6% for women younger than age 35 years, 5.3% for those aged 35-37 years, 1.7% for those aged 38-40, 0.6% for those aged 41-42, and 0.5% for those older than age 42.

The percentage of live births with twins has decreased only slightly over time, but only in the three youngest age categories. In 2003, those rates were 33.5% for women younger than age 35 years, 27.9% for those aged 35-37 years, 22.7% for those aged 38-40, 14.8% for those aged 41-42, and 7.3% for those older than age 42. By 2010 the percentage of live births with twins was 32.4% for women younger than age 35, 27.2% for those aged 35-37, and 22.1% for those aged 38-40, yet had increased to 16.9% for those aged 41-42 and 9.6% for those older than age 42.

Major Finding: In 2010, the percentage of treatment cycles resulting in live births among women younger than age 35 was 41.7%, compared with 31.9% for those aged 35-37, 22.1% for those aged 38-40, 12.5% for those aged 41-42, and 4.1% for those older than age 42.

Data Source: This is a summary of findings from 370 IVF clinics in the United States reporting data to the Society for Assisted Reproductive Technology Assisted reproductive technology (ART) is a general term referring to methods used to achieve pregnancy by artificial or partially artificial means. It is reproductive technology used in infertility treatment, which is the only application routinely used today of  on 146,693 treatment cycles leading to the birth of 58,727 babies.
