Brief summary

To assess the impact of cervical mucus cleansing before embryo transfer and compare two different instruments for this purpose.

Detailed description

All patients will be informed about the study and those who give written consent will be included in the study. Women undergoing good quality embryo transfer will be assigned to one of the 3 arms of the study according to the previously determined randomization chart. The first evaluation of the patient will be made on the 12th day after embryo transfer. Pregnancy status will be evaluated with serum βhcg value. If pregnancy is confirmed by serum βhcg value, fetal viability will be evaluated by ultrasound 4 weeks after transfer.

Interventions

PROCEDURECotton swab

Removal of the cervical mucus with a cotton swab before embryo transfer.

PROCEDURECannula

Removal of the cervical mucus with a cannula before embryo transfer.

Masking description

Participant masking: Embryo transfer is done while the patient is lying in lithotomy position in accordance with gynecological examination. The patient is informed about the preparations before the embryo transfer and then the examination is completed. The patient will not be informed about the method used for removal of the cervical mucus. The patient's lying position also does not allow observation of the material used to remove cervical mucus.

Intervention model description

It is a parallel model interventional study. The sample size is calculated as 180 patients. Sixty patients will be assigned to each study arm by randomization. It is planned to use random computerized numbers for randomization. İn arm 1, cervical mucus will be removed with a cotton swab before embryo transfer. In arm 2, cervical mucus will be removed with a canula before embryo transfer. In arm 3, cervical mucus will not be removed.

Inclusion criteria

* 21-40 years old women, * Women undergoing good quality embryo transfer, * Women who are eligible for a single or double embryo transfer.

Design outcomes

Primary

MeasureTime frameDescription
Detecting pregnancy after embryo transfer.12 days after embryo transfer/ intervention.Confirmation of pregnancy with serum βhcg value at the earliest 12th day after embryo transfer.
Confirmation of fetal cardiac activity in detected pregnancy.3-4 weeks after embryo transfer/ intervention.Evaluation of fetal cardiac activity on ultrasound.

Secondary

MeasureTime frameDescription
Success of embryo transfer during intervention.5 minutes after embryo transfer.In some cases, the embryo is transferred to the endometrial cavity and comes back with the transfer cannula. For this reason, the embryology laboratory checks the transfer cannula after the transfer. If the embryo is still in the embryo transfer cannula, a second attempt is made for embryo transfer. As a secondary outcome, we will evaluate the success in the first attempt for embryo transfer.
