You may be thinking… hmm, another weight and infertility post. But this time, the focus isn’t on your CURRENT weight but on how much you weighed when you were born 😄
… or even more importantly, what your husband/male partner/boyfriend’s weight was when he was born!
With about 50% of infertility cases due to men (in part or in whole), it’s so important that fertility research is not limited to just women. This particular study looked at infertility rates in both men and women.
Have a look at what researchers found:
Previous studies have found differences in (sex) hormone levels and testicular volume when comparing low birth-weight to average birth weight men. But until now, it wasn’t clear if this was associated with infertility later in life.
So researchers from Denmark wanted to explore just that. They discovered that men who were born very small for gestational age (birth weight below the 10th percentile), had up to a 55% increased risk of male-factor infertility later in life compared to men with a higher birth weight.
The higher risk can be partially explained by certain health conditions associated with premature birth as well as infertility. But for women, having a (very) low birth weight did not matter in terms of fertility.
