Summary
Many gamete intrafallopian transfer (GIFT) cycles are cancelled. However, cancelled GIFT cycles still offer viable pregnancy options through insemination or intercourse, achieving notable success rates.
Area of Science:
- Reproductive medicine
- Infertility treatments
- Assisted reproductive technologies
Background:
- Gamete intrafallopian transfer (GIFT) is an assisted reproductive technology.
- Cycle cancellation is a significant concern in GIFT procedures.
- Understanding outcomes of cancelled cycles is crucial for patient counseling.
Purpose of the Study:
- To determine the pregnancy rates following insemination or intercourse in cancelled GIFT cycles.
- To assess the reproductive potential of patients after GIFT cycle cancellation.
Main Methods:
- Retrospective analysis of GIFT cycles.
- Categorization of cycles into cancelled and completed.
- Tracking pregnancy outcomes in cancelled cycles based on subsequent insemination or intercourse.
Main Results:
- A substantial 44% of initiated GIFT cycles were cancelled.
- Insemination in cancelled cycles resulted in a 23% pregnancy rate.
- Intercourse in cancelled cycles led to a 10% pregnancy rate.
Conclusions:
- Cancelled GIFT cycles are common but do not necessarily represent a complete loss of reproductive opportunity.
- Insemination and intercourse represent viable, albeit lower, success rate alternatives post-GIFT cancellation.
- These findings can inform clinical decisions and patient expectations regarding cancelled GIFT cycles.
