Will IUI help us again ???

Patient: My age is 32 yrs. My husband age is also 32 yrs. 4 yrs. Past to our marriage, but still failed to conceive. Lastely from 6 months continuous treatment and observations. Last month we tried IUI. With HCG injected twice. But it also failed.So when this month when we consult again, advised to IUI with HMG injected 4 times. But unfortunately after 3 injection. Only one folic developed and found 4mm polyp in uterus. So avoided IUI this time.Now what direction we should go for?

Symptoms: 4mm polyp in uterus
