Ovarian reserve assessment in crohn patients of reproductive age.

OBJECTIVES
Crohn's disease (CD) is a repeating bowel disease characterized by remission and exacerbation periods. The disease mostly affects adults of reproductive age. Women with desires to conceive are concerned about the effects of CD on their fertility. To demonstrate the relationship between ovarian reserve and CD anti-Müllerian hormone (AMH) levels, antral follicle count (AFC) and ovarian volüme were evaluated.


MATERIAL AND METHODS
The prospective case-controlled study was conducted at a tertiary referral center in Istanbul between March-August 2019. Ovarian functions were evaluated in 50 patients with CD and in 95 healthy women. Serum gonadotropin and AMH levels were determined. AFCs and ovarian volumes were calculated for all subjects.


RESULTS
AMH levels were significantly lower in CD patients (2.1 ± 0.8) compared to the control group (3.3 ± 0.9) (P = 0.001). Serum AMH levels were significantly lower in patients with active CD (2.1 ± 0.6) than the CD patients in remission (2.6 ± 0.8) (p = 0.002). Ovarian volumes and AFC values were significantly lower in both ovaries in CD patients compared to the controls (p < 0.05).


CONCLUSIONS
AMH levels, ovarian volume and AFC counts, and thus ovarian reserve was shown to be decreased in CD patients of reproductive age compared to healthy control subjects. Because possible effects of inflammatory damage may be seen in newly diagnosed female CD patients who desire to have a child, we believe that CD patients should be comprehensively assessed for ovarian reserve.
