Disclosure patterns of mode of conception among mothers and fathers-5-year follow-up of the Copenhagen Multi-centre Psychosocial Infertility (COMPI) cohort.

Background: Most studies on disclosure of mode of conception after fertility treatment have focused on donor insemination. We present a large, longitudinal cohort study of fertility patients who conceived through a variety of fertility treatments, including both non-donor and donor techniques.

Methods: A cohort of 2812 women and men (n = 1406 couples) received questionnaires when initiating fertility treatment and at 1-year and 5-year follow-ups.
