Infertility in men with inflammatory bowel disease.
Inflammatory bowel disease (IBD) predominantly affects young adults. Fertility-related issues are therefore important in the management of patients with IBD. However, relatively modest attention has been paid to reproductive issues faced by men with IBD. To investigate the effects of IBD and its treatment on male fertility, we reviewed the current literature using a systematic search for published studies. A PubMed search were performed using the main search terms "IBD AND male infertility", "Crohn's disease AND male infertility", "ulcerative colitis AND male infertility". References in review articles were used if relevant. We noted that active inflammation, poor nutrition, alcohol use, smoking, medications, and surgery may cause infertility in men with IBD. In surgery such as proctocolectomy with ileal pouch-anal anastomosis, rectal incision seems to be associated with sexual dysfunction. Of the medications used for IBD, sulfasalazine reversibly reduces male fertility. No other medications appear to affect male fertility significantly, although small studies suggested some adverse effects. There are limited data on the effects of drugs for IBD on male fertility and pregnancy outcomes; however, patients should be informed of the possible effects of paternal drug exposure. This review provides information on fertility-related issues in men with IBD and discusses treatment options.
