Causes of Female Infertility

a. Prevalence data presented are based on the World Health Organization (WHO) task force on Diagnosis and Treatment of Infertility (90)

b. The chart on the left represents three broad classifications of the etiologies (hormonal dysregulation; anatomical or functional reproductive organ abnormalities; unexplained or unknown causes); the chart on the right denotes sub-classifications of these categories.

c. To our knowledge, the prevalence of the causes of female factor infertility have yet to be comprehensively and concurrently delineated. For example, a comprehensive accounting of population prevalence would include at least the following factors: hormonal dysregulation, anatomical or functional reproductive organ abnormalities, unexplained or unknown conditions, lifestyle and environmental influences, disease and iatrogenesis.
