Summary
Filling the bladder before embryo transfer does not improve success rates in in vitro fertilization. This randomized controlled trial found no significant difference in embryo transfer difficulty or pregnancy rates between women with and without a filled bladder.
Area of Science:
- Reproductive medicine
- Gynecology
Background:
- Anteverted uterus positioning can complicate embryo transfer.
- Bladder filling is hypothesized to straighten the uterus, potentially aiding transfer.
Purpose of the Study:
- To investigate if a filled bladder facilitates embryo transfer and improves pregnancy rates in in vitro fertilization (IVF).
Main Methods:
- A randomized controlled trial was conducted with 142 women undergoing IVF.
- Participants were assigned to either a filled bladder or non-filled bladder group.
- Difficulties during embryo transfer and pregnancy outcomes were assessed.
Main Results:
- No significant differences were observed in the ease of embryo transfer between the two groups.
- Pregnancy rates were comparable in women with and without a filled bladder.
Conclusions:
- Bladder filling does not appear to be a beneficial strategy for improving embryo transfer outcomes or pregnancy rates in IVF.
- Current practices for embryo transfer in IVF do not require bladder filling.
