Ulcerative colitis: female fecundity before diagnosis, during disease, and after surgery compared with a population sample.
OBJECTIVE
Women with ulcerative colitis generally have normal fertility. The aim of this study was to compare patients' fecundability before and after restorative proctocolectomy with ileal pouch-anal anastomosis with the fecundability of the general population.


METHODS
Historical follow-up was performed on 343 consecutive female patients aged 10.6-40.5 years at surgery and a reference population of 1200 women aged 25-40 years. A total of 290 (85%) patients and 661 (55%) women in the reference population agreed to participate in a structured telephone interview concerning reproductive behavior and waiting times to pregnancy. Cox regression and Kaplan-Meier plots were used for analysis.


RESULTS
Surgery significantly reduced the ratio of patient to reference population fecundability, which decreased to 0.20 (P < 0.0001). Before diagnosis and from diagnosis until colectomy, the fecundability of the patients was similar to that of the reference population.


CONCLUSIONS
Female patients with ulcerative colitis have normal fecundity before surgical treatment. Surgery severely reduces female fecundity. Information about this reduction in fecundity should be given before surgery, and if a woman has an unfulfilled wish for pregnancy after surgery, early referral to a gynecologist is recommended.
