Dear Irina! SCIENTIFIC references in occasion of planning a floor of the child does not exist. Certainly, there can be certain macrolaws, under what conditions the probability of conception of the certain floor is more probable, as the certain parity or ratio of floors in a population is supported or maintained by natural selection. BUT: the vector of selection is defined or determined very much by a lot or plenty significant faktorovi, and in each individual case PROBABLE value or meaning;importance of a vector of selection not so necessarily will precisely predict or forecast, what floor the child will be conceived in each concrete case. In particular, for example, there is an opinion, that in families of seamen of long voyage where the seasonal rhythm of a sexual life actually takes place, girls, than boys is more often are born. But it does not mean at all, that in such families boys as well as does not mean are not born, that in families with a regular sexual life boys is more often are born. The same concerns to planning conception during the certain periods of a cycle - the slightest deviations or rejections in the hormonal status of an organism, and microcyclicity is broken or disturbed. The sequence of events from the moment of an output or exit of a mature ootid till the moment actually conceptions is individual also: time and number of sexual certificates or acts (that usually serves as a strong point of occuring theories) - far not unique factors - is still, for example, number of active spermatozoons and t. Probably, in the future some of these factors also it will be possible to supervise item, but while about it or this to speak early.
