Sexual Transmission
Proper research has confirmed that Crohn’s disease is not sexually transmitted. Because sex organs are close to the rectum and some engage in anal intercourse, people may wonder if the disease can be transmitted when the stool from a person with Crohn’s disease comes in contact with another person. Research does not support this idea.
Although, some conditions with similar symptoms to Crohn’s can be sexually transmitted. Colitis [2] is one example of disease that is similar to Crohn’s and other inflammatory bowel disease except that it can be transmitted sexually. But it is a much different condition with distinct causes, according to a small 2015 study.
Conditions such as chlamydia [3] and syphilis [4] can cause STI colitis. These cause are sexually transmitted. However, there is no link between STIs and Crohn’s disease.
