It’s almost impossible to receive medical care, especially fertility or pregnancy care, without hearing all about weight. And polycystic ovary syndrome (PCOS) is a common condition that impacts both weight and fertility. However, the science on weight and fertility, like with health in general, is tricky and usually not as it appears. Higher body weight is frequently described as a “cause” of infertility, but this claim deserves a lot, and I mean a LOT, of scrutiny, as the research base supporting these claims is highly problematic. The reality is that fat women have been having babies throughout human history and women of any weight can struggle with fertility, miscarriage, or health issues.
