The association between Type-D personality and in vitro fertilization success among women with unexplained infertility.

Objective: To evalute the association between Type-D personality and in vitro fertilization (IVF) success in unexplained infertile women.

Methods: This was a cross-sectional study conducted at the IVF unit of a tertiary center between September 2017 - December 2019. The 21 items Beck Depression Inventory (BDI-21) and 14 items Type-D Scale (DS14) were noted from 256 unexplained infertile women undergoing an IVF cycle.

Results: Paternal educational level and clinical pregnancy were lower and depression was more prevalent in Type-Ds than non-Type-Ds. There was a positive correlation between BDI-21 scores and duration of infertility and cycle count. Age, paternal educational level, anti-mullerian hormone and metaphaseII number were lower and Type-D personality was more prevalent in women who failed to become pregnant than women who achieved pregnancy. After adjustment of factors affect the IVF success, clinical pregnancy was negatively associated with Type-D personality, age and low paternal educational level, whereas it was positively associated with infertility duration and single embryo transfer.

Conclusion: It seems that having a Type-D personality may negatively affect clinical pregnancy after IVF treatment in couples with unexplained infertility.
