Researchers in Britain and Brazil say a new twist on an old fertility treatment could dramatically improve a woman's chance of getting pregnant though invitro fertilization. This technique is called endometrial scratching. They studied 158 women who had undergone unsuccessful fertility procedures, 77 had received the scratch. Scientists say in the women who has the procedure, the pregnancy rate jumped to 49% from 29%, and it nearly doubled the number of live births to 42% from 23%. Doctors say they are not sure why the scratch works, but one theory is it wakes up the womb. By causing a little bit of damage, the womb has to sort of regenerate and fix its self. Researchers in Britain say they will keep studying the scratch with trials on more women until their final study is released next year.
