[The epidemiology of infertility in families]

This study of epidemiology of infertility in families has employed the guidelines of the WHO Program on Human Reproduction. The study involved 1976 infertile couples. It elucidated major diagnosis-related groups in the female and male population and data sets of the couples. The basis of infertility remained uncertain in only 2.1% of the families. Infertility was underlied only by a female reproductive disease in 44.4% of the families, with about half of these cases being endocrine disorders. Diseases of husbands, primarily varicocele and primary testicular lesions, accounted for infertility in 19.3% of the families. Determinants of infertility in both spouses were identified in 34.2% of the families, mostly genital inflammatory diseases.
