any success with letrozole (femara) dexamethasone and iui

Ariel
My RE prescribed 2.5 mg letrozole cd 5-9 and .5 mg dexamethasone days 3-14, and possibly trigger ovulation before <a href="https://glowing.com/glow-fertility-program">IUI</a>.  Has anyone been prescribed this combination when ttc?  What were your side effects and did you have success?  I have elevated androgen levels and my husband has poor sperm morphology.  We ttc for two and a half years naturally before seeing a specialist.  So far we've done two <a href="https://glowing.com/glow-fertility-program">IUI</a>'s where I took letrozole, both BFN.  How many <a href="https://glowing.com/glow-fertility-program">IUI</a>'s did you do before getting a BFP or moving onto <a href="https://glowing.com/glow-fertility-program">IVF</a>?
