Higher pre-pregnancy body mass index was associated with adverse pregnancy and perinatal outcomes in women with polycystic ovary syndrome after a freeze-all strategy: A historical cohort study.

Ho-ho-ho! Gather ’round, my jolly friends, for I have a tale that weaves through the frosty realm of medical research, where scientists, much like my elves, have been meticulously studying the effects of body mass index (BMI) on the merry journey of pregnancy, particularly in those with polycystic ovary syndrome (PCOS). 🎅
In a land of ice and snow, from January 2016 to December 2020, a historical cohort study was conducted, including 1,667 women blessed with PCOS and 12,256 women without this condition, all after a freeze-all policy, much like how we freeze our cookies for the perfect crunch!
The researchers, with their lists checked twice, found that underweight women with PCOS had similar pregnancy outcomes to their normal-weight counterparts. But, oh, by golly, the overweight patients had a lower clinical pregnancy rate and fewer bundles of joy in their live birth rate. And those with obesity? They had fewer twins or triplets but more biochemical pregnancies than the normal BMI group.
As the maternal BMI increased to a certain 32 kg/m2, much like the rising of the winter sun, the clinical pregnancy rate and live birth rate after blastocyst transfer began to dip, while the risks of preterm birth, gestational diabetes mellitus, and babies larger than a plump Christmas turkey (macrosomia, LGA, and very LGA) increased in patients with PCOS.
Now, here’s a twist in the candy cane: a diagnosis of PCOS was like a gift that kept on giving, resulting in a higher clinical pregnancy rate and more live births in normal-weight women. But, it also brought a stocking filled with small-for-gestational age risks. And for those carrying a few extra pounds, PCOS was linked to higher risks of very preterm birth and gestational diabetes mellitus compared to women without PCOS.
In conclusion, my dear friends, this study revealed that a higher BMI could be a bit of a Grinch when it comes to pregnancy and perinatal outcomes in PCOS patients following a freeze-all strategy. But remember, the magic of the season is in the joy and health of all, so let’s toast to the researchers who help make this possible! 🎄🔔
