title: Comparative study of the impact of past pregnancy outcome on future fertility.
abstract: BACKGROUND
  The impact of previous pregnancy outcome on future fertility in Nigeria has not been appreciated, hence the continued neglect of the adoption of safe motherhood measures in this sub-region. The objective of this study was to compare the past pregnancy outcomes among fertile and infertile patients in a Nigerian population.
  
  
  METHODS
  An institutional-based comparative case-controlled study of past pregnancy outcomes among infertile and fertile women was conducted. The data was managed using Epi-Info and the Statistical Package for Social Sciences.
  
  
  RESULTS
  708 patients consisting of 472 pregnant women (fertile) and 236 infertile women were investigated. Infertile women were at a significant risk of having an adverse pregnancy outcome, such as induced abortion (p-value is 0.0001), postabortal sepsis (p-value is 0.0001), postpartum infection (p-value is 0.001), manual removal of the placenta (p-value is 0.0005) and prolonged unsupervised labour (p-value 0.0001), compared to pregnant fertile women. Logistic regression analysis of variables at 95 percent confidence intervals showed that the adjusted odds ratio for prolonged labour, prolonged rupture of membranes, postabortal sepsis and postpartum infection still remained significant.
  
  
  CONCLUSIONS
  Previous mismanaged pregnancies impacted negatively on future fertility. Efforts should be directed towards the prevention of unplanned pregnancies. Motherhood must be made safer in planned pregnancies by prevention of complications, and aggressive and prompt treatment of any complication if and when it occurs.
