[Status of studying the reproductive function of women--passenger train engineers]

Analysis of medico-demographic indices of 3450 women--conductors of passenger long-distance trains give evidence of the presence of changes in the status of the reproductive function. Birth indices are low, in spite of favourable marriage levels. Childlessness levels in women working on trains are 5-6 times higher compared to the average values in the country. Unfavourable tendencies are observed in women of any age, however, they are more profoundly marked in older women who have been handling maximal contact with harmful occupational factors during many years of work. Significant relationships have not been observed between birth level and such parameters as nationality, place of living, educational level etc.
