IVF Procedures In 2012 Led To Record Number Of Births

By Karen Kaplan, Los Angeles Times

LOS ANGELES — More than 1.5 percent of babies born in the U.S. in 2012 were conceived in a laboratory dish thanks to in vitro fertilization — an all-time high, according to a report released Monday by the Society of Assisted Reproductive Technology.

The 379 fertility clinics that are members of SART performed a total of 165,172 procedures in 2012, resulting in the births of 61,740 babies. Both figures are new records as well, SART says.

In more than 99 percent of the cases, the reproductive technology used was IVF. Two methods that are more invasive — gamete intrafallopian transfer (GIFT) and zygote intrafallopian transfer (ZIFT)– made up less than 1 percent of the total.

For women under the age of 35, 40.7 percent of fertility treatment attempts resulted in a live birth. So did 31.3 percent of the attempts by women ages 35 to 37; 22.2 percent of the attempts by women ages 38 to 40; 11.8 percent of the attempts by women who were 41 or 42; and 3.9 percent for women who were 43 or older.

The clinics reported progress toward their goal of reducing the number of multiple births, especially higher-order multiples (triplets, quadruplets, or in the worst-case scenario, Octomom). The expense of IVF prompts most couples to transfer more than one embryo in a cycle, to improve the odds that at least one will implant.

However, doctors were able to persuade women under the age of 35 to transfer a single embryo in 14.8 percent of the cycles. The story was the same for 8.9 percent of cycles involving women ages 35 to 37. That helped push down the average number of embryos transferred per cycle of IVF to 2.0 or lower.

Even for women in the oldest cohorts, the average number of embryos transferred was still below 3 (though just barely — it was 2.9).

Mothers under the age of 35 gave birth to twins in 29.5 percent of the treatment cycles. Twins were also born 25 percent of the time to mothers between the ages of 35 and 37; 20.3 percent of the time to mothers ages 30 to 40; 13.4 percent of the time to mothers who were 41 or 42; and in 9 percent of cycles among mothers who were 43 or older.

Triplets and higher-order multiples were rare, accounting for only 1.1 percent of cycles in the youngest group of women and less than 1 percent for older mothers.

Remembering A Great American: Edwin Fancher, 1923-2023

Norman Mailer, seated, Ed Fancher and Dan Wolf, founders of The Village Voice

If you are lucky in your life, you come to know one or two people who made you who you are other than your parents who gave you the extraordinary gift of life. Edwin Fancher, who it is my sad duty to inform you died last Wednesday in his apartment on Gramercy Park at the age of 100, is one such person in my life. He was one of the three founders of The Village Voice, the Greenwich Village weekly that became known as the nation’s first alternative newspaper. The Voice, and he, were so much more than that.

How Is That Whole 'Law And Order' Thing Working Out For You, Republicans?

Former Georgia Republican Party chair David Shafer

One of the great ironies – and there are more than a few – in the case in Georgia against Donald Trump and 18 co-defendants is the law being used against them: The Georgia RICO, or Racketeering and Corrupt Organizations Act. The original RICO Act, passed by Congress in 1970, was meant to make it easier for the Department of Justice to go after crimes committed by the Mafia and drug dealers. The first time the Georgia RICO law was used after it was passed in 1980 was in a prosecution of the so-called Dixie Mafia, a group of white criminals in the South who engaged in crimes of moving stolen goods and liquor and drug dealing.
