OP again - agreed, yes, such can often be modified through things like lifestyle changes. Or not, if that is the size and BMI that your body naturally is.
Also if time is a factor - which in my case it is because I am AMA - taking ‘a few months to lose some weight’ may not be an option. In fact, my doctors and even SGF specifically recommend NOT doing this, rather, encourage me to keep focusing on the healthy habits such as balanced eating and regular exercise. I would love if taking the time needed to healthily lose weight was an option, and had very much been working on this prior to TTC. Nor am I interested in quickly and unhealthily losing weight.
With my specific case, though (which is all I can speak to), my health and hormonal metrics indicate that I am extremely healthy. Given that, I was not presented any data, studies, or analysis on why my weight or BMI might be the issue, as such issues frequently present as hormonal imbalances, which I do not have. The Dr’s response when I asked that question: “we don’t know why, then, but it may be.” Not a great answer, and fell into the realm of fertility fat shaming for me.

From article above: “Research suggests that BMI alone frequently misclassifies metabolic health, which is linked to how much fat a person has and how it is distributed. And, BMI may be particularly unreliable during pregnancy, for athletes, and the elderly.“
