title: [The role of environmental and genetic factors in the development of pathology of the reproductive system in girls].
abstract: Genetic and environmental effects on reproductive development of girls are described. Possible genetic involvement is postulated in girls with opsomenorrhea, second-degree amenorrhea and juvenile bleedings. Abnormal development of the menstrual function is more commonly associated with chronic tonsillitis, stress or weight loss. Environmental effects are particularly frequent and pronounced one year before or during the menarche. Central menstrual disorders were associated with parental reproductive disorders in 47% of the cases.
