Ivf prep

I’m pretty certain my husband and I will be told ivf is our best option, we have a month until our follow up and on a wait list for fertility clinic so realistically we probably have a few months. Does anyone have any advice or supplements they recommend? I want to make sure my body and eggs and his sperm is in tip top shape for best outcomes! Thanks

Back story - we are 29&32 , I am as far as we can tell perfectly fine, ovulate regularly hsg/ bloodwork is good. His motility count is just very low.

Thanks!
