[The problem of modifying X-chromatin frequency using hormonal contraceptives].
The ability of the sexual steroids to induce extragenital organ-effects is set in connection to the preovulatory decrease of x-chromatin frequency during the regular menstrual cycle as found by Schmidt and coll. [11]. Under modified techniques of investigation and exact criteria of selection, reproducibility of the results and the behaviour of the x-chromatin-frequency in the artificially controlled anovulatory cycle are checked. The absence of preovulatory decrease shows that a hormonal influence may be assumed.
