Summary
This study found no significant difference in pregnancy rates between rigid and flexible catheters during intrauterine insemination (IUI). Both catheter types are equally effective for infertility treatment.
Area of Science:
- Reproductive Medicine
- Infertility Treatment
- Assisted Reproductive Technologies
Background:
- Intrauterine insemination (IUI) is a common infertility treatment.
- Catheter choice during IUI may influence procedure success.
- Limited comparative data exists for rigid versus flexible IUI catheters.
Purpose of the Study:
- To prospectively compare pregnancy rates in couples undergoing IUI.
- To evaluate the efficacy of rigid (Tomcat) versus flexible (Cook) insemination catheters.
Main Methods:
- Randomized, controlled study at a tertiary care infertility practice.
- 100 infertile women underwent IUI, with 95 receiving ovarian stimulation.
- Timed IUI performed using either rigid or flexible catheters.
Main Results:
- No significant differences observed in patient demographics or cycle parameters between groups.
- Pregnancy rates per cycle were comparable for rigid and flexible catheter groups.
- Insemination ratings and stimulation protocols showed no variation between catheter types.
Conclusions:
- Flexible and rigid IUI catheters demonstrate no statistically significant difference in efficacy.
- Catheter type does not appear to be a determining factor in IUI success rates.
- Clinicians can utilize either catheter type for IUI procedures.
