Pregnancy and Crohn's Disease

Abstract: Summary: Of 77 married women with Crohn's disease, 25 were sterile. In the remaining 52 (98 pregnancies) the risks of prematurity, stiilbirth, abortion, or congenital abnormality were not increased. There was no evidence that pregnancy exerted adverse effects on the course of the disease or increased the mortality rate. Sterility was the main problem encountered.

“…While spontaneous abortion rates in patients with quiescent disease at the time of conception disease to age-matched controls found no significant difference in the ability to conceive [4,5], earlier data are similar to those of control groups [12], there is a 60% risk of postoperative spontaneous abortion in those demonstrate reduced fertility [2,6]. Furthermore, one study indicates that colonic as opposed to ileal involve-patients requiring surgical intervention for disease refractory to medical therapy and nonoperative decompression ment leads to greater infertility, 67 versus 26% [7]. Prior studies did not consider disease localization when exam- [13].…”

“…By comparison, UC has less of an effect on fertility, unless patients had undergone any IBD related surgery [12,13] . Several other factors associated with active IBD can also contribute to the overall lower rate of conception in IBD including dyspareunia, low libido, and depression [14][15][16] . Dyspareunia (painful sexual congress) often occurs secondary to pelvic surgery, from IBD-associated inflammation, or psychological stress associated with IBD.…”

“…Reasons for this are likely multifactorial and may be related to fever, pain, diarrhea and malnutrition frequently seen in IBD flares, as well as dyspareunia, decreased libido and depression [10][11][12]. There may also be an immunologic basis involving T-cell dysfunction given young infertile women without IBD but with Th1/Th2 cytokine elevation have improved in vitro fertilization rates using adalimumab, which as a TNF-α inhibitor has been proposed to cause a shift in the Th1/Th2 balance [13].…”
