Brief summary
Multiple pregnancies are considered an ART complication. The only effective way to reduce its incidence is to transfer a single embryo. Nonetheless, there is some reluctance among the patients to accept this strategy. In IVF/ICSI programs, it has been demonstrated that, after receiving the information about the similar cumulative live birth rate after single embryo transfer (SET) and double embryo transfer (DET) and the obstetric and perinatal risks of multiple pregnancy, a significant number of patients opt for SET. Up to date, no comparable studies have been published in oocyte recipients. The aim of this study is to evaluate if the information given to the patients influence their preference on the number of embryos to be transferred. It also seeks to identify factors which determine the initial preference and factors which can explain a hypothetic change in this preference.
Interventions
BEHAVIORALOral and written counselling
Recipients were informed about success rates of SET and DET and also about the possible risks of DET. All the information was given orally and written.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Preference change on the number of embryos to be transferred | Up to 3 months | Preference was evaluated at the first consultation and after counselling using a self-report questionnaire. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Factors which determine the initial preference on the number of embryos to be transferred | At the first consultation | Factor's weight is analysed using a self-report questionnaire. Each factor is scored 1-10 according its relevance. |
| Factors which can explain a change in the preference on the number of embryos to be transferred | Up to 3 months | Each factor is scored 1-10 according its relevance. Score before counselling and score after counselling were compared. |
