The effectiveness of several measures that may reduce the risk of luteal phase pregnancies after interval tubal sterilization was analyzed. Using data from the Collaborative Review of Sterilization on 5495 women, 18 luteal phase pregnancies were identified. Women who underwent sterilization after their estimated date of ovulation had a low risk of having a luteal phase pregnancy if they used oral contraceptives or an intrauterine device in the month before sterilization. Of the 18 luteal phase pregnancies, 14 (78%) occurred among the 16.8% of the women who were sterilized after their estimated date of ovulation and who had used barrier, rhythm, or withdrawal methods of contraception in the month before sterilization. The use of concurrent dilatation and curettage in these women at increased risk of luteal phase pregnancy did not lower their risk to that of women who were sterilized before their estimated date of ovulation.
