ASRM reviews fertility highlights


At the American Society for Reproductive Medicine’s (ASRE) annual meeting last week they discussed two topics recently in the news: the success ratio of multiple attempts at in vitro fertilization and the correlation between a woman’s weight and her fertility potential. Both topics have had several articles and research papers devoted to exploring them. At the meeting they brought it all together.

It’s long been a tough question to answer: how many attempts at IVF should a woman go through before giving up? This year’s research teams have provided an answer: depending on your personal situation, after three attempts your chances at success diminish. For most women, give it three tries and then move on to something. Else. The report they considered at the ASRM meeting was out of Michigan State University where they analyzed data on more than 500,000 million IVF attempts from about 300,000 women. The first try had a 36% success rate, the second try was 48% success rate and the third try was 53%. After that it levels off. Barbara Luke from MSU summed up “if women haven’t gotten pregnant by the third attempt the chances are slim to continue.”

Two studies presented at the ASRM meeting concluded that a woman’s weight does in fact affect her fertility. The first study compared menstrual cycles with the height and weight of women using assisted reproductive technology. As women got larger, their chances of conceiving via ART got smaller. For the second study, researchers at Harvard University and Brigham and Women’s Hospital in Boston examined egg and embryo quality as compared to body mass indices. Eggs from high BMI women produced immature oocytes through ART. These eggs are not likely to produce a live birth.
