Medically assisted reproduction and the risk of preterm birth: a case-control study using data from the Quebec Pregnancy Cohort.

ABSTRACT:

Background

The use of fertility treatments has been growing over the past decade, but these treatments are not without risk. We aimed to quantify the risk of preterm birth associated with the use of ovarian stimulators (OS) and assisted reproductive technologies (ART) overall and by type of fertility treatment.

Methods

We conducted a case-control analysis of data from the Quebec Pregnancy Cohort. We included singleton pregnancies ending in a live birth during the time when Quebec operated a universal reimbursement program for assisted reproduction (2010-2015). Fertility treatments were defined dichotomously, and pregnancies resulting from spontaneous conception were used as the reference. We categorized fertility treatments into subgroups: ovarian stimulators alone, ART alon
