Rock-A-Bye … Embryo?!
January 20, 2010While trying to improve the survival rates of embryos during the IVF process, researchers came across this astounding discovery.
Just like Mom used to do
According to MSNBC, “by gently rocking embryos while they grew during in vitro fertilization, scientists increased pregnancy rates in mice by more than 20 percent. The same rock-a-bye procedure could lead to more success for in vitro fertilization in humans, the researchers say.” Statistics show that only a small portion (about 35%) of fertilized eggs survive the implantation, so these efforts to increase their viability is encouraging news to waiting parents with infertility problems.
“One of our goals for years now has been to modify how we grow embryos in the lab to be more like how they grow in the human body, because we know that the human body grows them most efficiently,” said Gary Smith, associate professor of Obstetrics and Gynecology at the University of Michigan, Ann Arbor.
The hand that rocks the cradle…
It’s been said that the hand that rocks the cradle rules the world. But, what happens when it’s a scientist that does the rocking? In this case, it can make a world of difference. Mimicking the motion embryos experience in the body as they make their way down the woman’s Fallopian tube to the uterus, Smith’s device gently rocks them to their destination. “By making the cells feel more at home, we get better cells, which is key to having better infertility treatment,” said study researcher Shu Takayama. An added benefit–the device allows nutrient-rich fluids to flow in and waste to move out. The periodic “rocking” by the fluid flow fosters a more healthy environment.
