Among married men and women who undergo surgical sterilization through a vasectomy or a tubal ligation, it has been estimated that anywhere from ten to twenty percent will come to regret the choice. Sometimes there may be an immediate awareness of wrongdoing following the surgery, while in other cases, as Patrick Coffin, radio host and author of Sex au Naturel notes, sterilized couples may “…drift for years before acknowledging that something between them is no longer in sync. After the initial pregnancy fear subsides, and the vision of 1001 erotic nights turns out be something of a scam, spouse may (subtly) turn against spouse while doing their best to ignore the silent, disturbing ‘presence’ of the choice they made.”
