Nicole here too, it's such a monstrous road and so very very heartbreaking to have to go through full stims time after time. I sincerely hope that things become easier for you soon.

Something non medical that people have used on BB is royal jelly (the icky jelly stuff is apparently better than capsule form)... And I can say from myself and a friend of mine, we certainly found our egg quality improved through using it. The additional trick to it though is for you and your partner to take it, with the idea that sperm and egg will be more compatible because they have similar make up iykwim...
Also people have recommended menevite for men's sperm issues... I have no personal experience but some women here have certainly reported improvements.
