Infertility Among African American Women With Systemic Lupus Erythematosus Compared to Healthy Women: A Pilot Study.

Objective: Some treatments for systemic lupus erythematosus (SLE) can cause infertility, but the effect of SLE itself on fertility, particularly in African American women, is less clear. We undertook this study to examine infertility experiences in African American women with SLE compared to healthy women.

Methods: We enrolled women ages 22-40 years living in the Atlanta metropolitan area who were diagnosed with SLE after age 17 years. Women who had ever been treated with cyclophosphamide or who had a hysterectomy were excluded. African American women ages 22-40 years who were from the same area and recruited from a marketing list were used for comparison. Women were interviewed about their reproductive histories and goals. Periods of infertility were identified as times when women had regular, unprotected sex for ≥12 months without conceiving after 20 years of age. We separately considered any period of infertility and periods of infertility when attempting pregnancy. We used Cox proportional hazards regression to examine the association between SLE and time to infertility. Models were adjusted for age, nulliparity, and smoking. An age-matched analysis was also conducted to examine periods of infertility occurring after SLE diagnosis.

Results: Our sample included 75 women with SLE and 154 women without SLE. SLE was associated with any infertility (adjusted hazard ratio [HR ] 2.08 [95% confidence interval (95% CI) 1.38-3.15]), but less so with infertility when attempting pregnancy (HR 1.30 [95% CI 0.62-2.71]). The matched analysis generated similar point estimates.

Conclusion: Women with SLE may be more likely to experience episodes of infertility, but this may not translate to an inability to meet reproductive goals.
