Understanding IUI Success Rates: What to Expect

IUI Success Rates by Age

Success rates for IUI vary significantly with age:

Under 35: 15-20% per cycle

35-37: 12-15% per cycle

38-40: 8-12% per cycle

Over 40: 5-8% per cycle

Sperm Quality

Higher sperm counts and motility after washing lead to better outcomes. A post-wash count of over 10 million motile sperm is ideal.

Ovarian Response

Women who respond well to ovulation induction medications and produce 2-3 follicles have higher success rates.

Timing

Precise timing of insemination relative to ovulation is critical. Ultrasound monitoring helps optimize this.

Diagnosis

Unexplained infertility responds best to IUI

Mild endometriosis has moderate success

Severe male factor may need IVF instead

Most specialists recommend trying 3-6 IUI cycles before moving to IVF, depending on your age and diagnosis.

Maintain a healthy BMI

Avoid smoking and alcohol

Take prenatal vitamins

Manage stress

Follow your doctor's medication protocol precisely
