Endometriosis and the risk of postpartum depression: a Danish register-based cohort study

Endometriosis may be linked to postpartum depression and any association may differ according to prior psychiatric history and/or fertility treatment. We aim to examine the risk of PPD in women with endometriosis compared with those without using nationwide registry data. We further assessed whether this association varied according to (i) prior psychiatric history and (ii) conception by medically assisted reproduction (MAR), both of which are closely linked to endometriosis.
