IUI & Endometriosis?

Do you know if IUI is contraindicated for patients with endometriosis? 
​My doctor did a laparoscopy and she found and treated stage 2 endo. A few days later she had me do my first IUI
I've been reading Dr Sher's book In Vitro Fertilization: The ART of Making Babies.  He says in this book that endo creates a hostile environment for the egg and that IUI isn't likely to work and patients should go to IVF
​Have you heard of this before?  What does your doctor say?
