Résumé
Pregnancies conceived by To compare the prevalence and types of complications of the third stage of labor following vaginal delivery of singleton infants born to matched groups of women who conceived through IVF or spontaneously. A retrospective case-control study design was used. The electronic delivery files of a tertiary medical center were reviewed for all women with a singleton IVF pregnancy who gave birth by vaginal delivery from August 2011 to March 2014. The women were matched 1:2 for age, gravidity, parity, and week of delivery to women with a singleton spontaneously conceived pregnancy who gave birth by vaginal delivery during the same period at the same hospital. The impact of mode of conception on the length and complications of the third stage of labor was evaluated. The study group consisted of 242 women with IVF pregnancies (cases), and 484 matched controls with spontaneously conceived pregnancies (controls). The length of the third stage was similar in the cases and controls (14.23 ± 8.89 and 13.69 ± 9.19 min, respectively). IVF pregnancy was associated with a significantly higher rate of postpartum hemorrhage (PPH) (5.79 versus 1.45%, After correction for confounders, IVF conception proved to be a significant independent risk factor for PPH, manual removal of the placenta, and blood transfusion in the third stage of labor. Therefore, the management of women who give birth vaginally following IVF pregnancy should be designed to anticipate complications in the third stage even in the absence of other risk factors.

A retrospective case-control study design was used. The electronic delivery files of a tertiary medical center were reviewed for all women with a singleton IVF pregnancy who gave birth by vaginal delivery from August 2011 to March 2014. The women were matched 1:2 for age, gravidity, parity, and week of delivery to women with a singleton spontaneously conceived pregnancy who gave birth by vaginal delivery during the same period at the same hospital.

CONCLUSIONS
After correction for confounders, IVF conception proved to be a significant independent risk factor for PPH, manual removal of the placenta, and blood transfusion in the third stage of labor. Therefore, the management of women who give birth vaginally following IVF pregnancy should be designed to anticipate complications in the third stage even in the absence of other risk factors.
