What effects can colorectal surgery have on my sex life?

Generally minimal: It relly depends on what time of surrgery you are having. However, the only colorectal procedure that may lead to sexual side-effects is surgery for low rectal cancers. Most of the side-effects from this surgery are for men, as well.

Few: Rectal resection carries a small risk of retrograde ejaculation and impotence.

Impotence: Pelvic surgery or ima dissection can affect retrograde ejaculation or impotence in men.
