Are you considering pregnancy but have questions regarding how your IBD may affect fertility or pregnancy outcomes?

You are not alone. Many people with IBD have questions regarding their IBD or IBD treatments and pregnancy. Many survey studies around the world have observed that more than 50% of the surveyed women had a lack of knowledge about IBD and pregnancy1. More than 50% of surveyed women were childless, and more than 10% said they chose not to become pregnant (“voluntary childlessness”). Our 2014 survey study and previous studies showed that the concerns women with IBD have are often based on a lack of knowledge and/or incorrect information. Therefore we hope the information resources we present here will help you.

Prepregnancy FAQ

I have an ostomy, where can I find information on sex, intimacy, and fertility?

Sex & Intimacy

If you have an ostomy, either ileostomy or colostomy, here are some handy tips on sex, intimacy, and fertility.

I have Crohn’s disease and need a resection – how could this surgery affect my fertility?

Fertility

For patients with Crohn’s Disease, two common surgeries are the ileal (small bowel only) resection and the ileocolic (small bowel and part of large bowel) resection. During these surgeries the portion of the bowel that is strictured or diseased is removed and the healthy ends are attached. These surgeries usually do not interfere with the reproductive organs and are unlikely to affect fertility. However, adhesions (scar tissue) can form from any surgery, and adhesions that block the fallopian tubes can lead to infertility.

I have ulcerative colitis and need a colectomy – how could that affect my fertility?

Fertility

For patients with ulcerative colitis unresponsive to medical therapy, colectomy is often needed. The small intestine is brought up to an opening in the abdominal skin and formed into an ostomy (Image B).  An ostomy bag sits outside to collect the waste.  The ostomy can be a permanent end-ileostomy, or a temporary ostomy, depending on the situation.

In some cases, the ileum (small bowel) is brought down into the pelvis, shaped into a pelvic pouch, and connected to the anus – ileal pouch-anal anastomosis (IPAA, or J-pouch) surgery.

Since the surgery occurs deep in the pelvis, injury can occur to the fallopian tubes (a reproductive organ through which an egg travels from the ovary to the uterus); scarring and adhesions that form after the surgery can block the fallopian tubes.  

For women who need a colectomy but also wish to have children, it is suggested that they have the colectomy with a temporary ileostomy until they have finished having children.  Then they can undergo the IPAA procedure to create a J pouch.

I have IBD, will my child have IBD?

Risk of IBD

Having a family history of IBD and having certain genes can predispose a person to developing IBD. The risk is less than 10% if one parent has IBD, and about 20-30% if both parents have IBD1.

There are factors other than genetics that can affect the risk of developing IBD

Having a family history of IBD and having certain genes can predispose a person to developing IBD. The risk is less than 10% if one parent has IBD, and about 20-30% if both parents have IBD1.

There are factors other than genetics that can affect the risk of developing IBD

  • The environment is important . . .
    • The environment can provide triggers that lead to the development of IBD. There is a relatively high prevalence of IBD in Western and developed countries2,3. However, the incidence of IBD is rising in developing countries. Children who immigrate take on the risk associated with the country to which they are moving4. Living in an urban setting is associated with an increased risk of developing IBD – this association appears to be stronger for developing Crohn’s disease than ulcerative colitis4.
  • Smoking may play a role . . .
    • Smoking has been reported to be a risk factor for developing and worsening of Crohn’s disease, but a protective factor for developing and for decreasing disease activity in ulcerative colitis2,3.  However, it is not recommended to smoke to decrease the risk of developing ulcerative colitis because of the risks associated with smoking (such as lung cancer, cardiovascular disease, and other health problems).
  • Diet may be important . . .
    • Although studies vary, diets rich in dietary fiber (fruits and vegetables) are thought to be protective against IBD3.  Consuming excessive meat, fish, and fats may increase the risk of developing IBD2,3.
    • Vitamin D has been found to be low in IBD patients and Vitamin D deficiency may lead to immune deregulation and increase the risk of developing IBD5.
  • The intestinal microbiome is important . . .
    • The intestinal microbiome is made of all the bacteria in an individual’s gastrointestinal tract. It is established in infancy and childhood.
    • The microbiome helps to maintain a healthy immune system by
      • opposing certain inflammatory cytokines
      • regulating the development of immune cells that recognize foreign- and self-compounds
      • activating T regulatory cells, which can promote tolerance to microorganisms6
    • The intestinal microbiome needs to be balanced for each individual to have a healthy immune system.
  • Many things affect the intestinal microbiome . . .
    • The intestinal microbiome can be affected by a person’s genes, their environment (including diet), overall health, infections, and medications (such as antibiotics).
  • An unbalanced intestinal microbiome can lead to a dysregulated immune response . . .
    • Multiple factors interact and can lead to a change in the intestinal microbiome. An unbalanced intestinal microbiome can lead to a dysregulated immune response resulting in inflammation characteristic of inflammatory bowel disease.
    • the “hygiene hypothesis” proposes that clean environments limit microbial exposure, leading to an altered immune system that is unable to differentiate between beneficial from harmful bacteria2,3
  • the altered immune system can predispose one to exaggerated immune responses, resulting in the chronic inflammation seen in IBD
