ObjectiveTo determine demographic characteristics associated with pregnancy and, separately, discontinuation of infertility services when unsuccessful at achieving pregnancy, among a national sample of women who received infertility services.DesignUsing a log-linear regression model, we examined associations with becoming pregnant among women who had received infertility services; and using a Cox proportional hazards model, we examined associations with earlier infertility service discontinuation.Setting2002 National Survey of Family Growth, Cycle 6.Participant(S)A total of 530 women aged 18-44 years in the 2002 National Survey of Family Growth who had received infertility services.Intervention(S)None.Main Outcome Measure(S)Relative risks for predictors of pregnancy after receiving infertility services; median time to discontinuation of infertility services; hazard ratios for predictors of earlier discontinuation of services.Result(S)Fifty-nine percent of respondents became pregnant while receiving infertility services, and 32% reported discontinuing infertility services before establishing a pregnancy. Women received infertility services for a median of 8 months; among those who discontinued services, more than half did so within 1 month. Among women who received infertility services, those who were white, nonsmokers, nulliparous, had insurance coverage, and received more than advice had a higher likelihood of pregnancy. Non-whites, parous women, and smokers discontinued infertility services earlier than others.Conclusion(S)Patients should be adequately counseled regarding modifiable behaviors and the range of services available before making decisions regarding their infertility.
