[Elaboration of a device for detection of the ovulation period in women].

The results are described of studies for evolving of modern methods for determination of the ovulation time in women. After an analysis of literature reports three methods were chosen based on differences in body temperature measurements and a measuring device for these experiments was designed. The results are presented of preliminary experiments with this method of "measurements of changes in the reactivity of blood vessels". Further studies can be conducted only by physicians, and the paper contains proposals of using this device as well as the literature data.
