Abstract

We quantified incident pregnancies among reproductive-aged women with and without Schistosoma haematobium infection. Among 245 women, 59 (24.1%) became pregnant during a median follow-up of 370 days. Women with S. haematobium infection had a 52% lower rate of pregnancy within the study period compared with uninfected women (hazard ratio = 0.48 [0.29-0.80], P = .005).
