Bub,
In TCM, our body is being analyse into hot, cold type and further into "nei xu", "nei re", etc... Durian is "hot fruit" by nature, theoretically eating durian can "bu" n "warm" the womb. I took TCM last time to "bu" and the pills I ate pretty "warm", can felt impact like body temper increase n also tummy warmer. Shin sei told me women has infertility would having "cold" womb in common.
