Success with donor eggs and low morphology sperm?

Hi

At age 44 and after numerous failed ivf and miscarriage I have decided to move on to donor eggs. My partner just took another soerm analysis and his morphology is 1%. My RE says that's "acceptable" for ivf with ICSI.

But I feel nervous and am searching for more info. Anyone have thus problem and improved morphology or gotten pregnant with DE with that low morphology?

I feel like this is a never ending journey of hurdles!

Thanks!
