A biological calculation rule, consisting essentially of a calculation rule provided with two slides that fit together and slide with each other and with the rule itself, being characterized by the fact that in the upper zone of the rule it is provided with divisions from 1 to 56, which represent days of the menstrual cycle. The lower part of the rule presents important and frequently used biological and chemical constants in all its extension, the upper section presents divisions corresponding to the natural days of the month and the scale goes from five in five units to the thirty division, continuing with divisions of one in a unit until twenty-eight, with which the reglilla presents divisions for a month of thirty days and another of twenty-eight. In addition, this reglilla presents the right, left indications in each respective end. Finally, the lower row indicates the periods of sterility and fertility for which it presents first a blank space followed by an entry that goes from right to left, dividing the numbering in distinctive colors, until eleven a color, then eight divisions of another color that indicates the period of fertility, followed by a new scale that starts at zero and continues until thirty-one and is the same color as the zone from zero to eleven and indicates sterility like that.
