Starting IVF

I'm starting <a href="https://glowing.com/glow-fertility-program">IVF</a> in December... My husband and I have been trying for a little over 3 1/2 years... We have had 6 failed IUIs... So I think we are ready to try something a little more extreme! Does anyone have any advice on how they were successful? I don't have an issues it is solely a sperm count, shape, and movement issue. Appreciate anything!!
