"Jonas Birth Control"

Theory advanced by Dr. Eugen Jonas of Czechslovakia.

It states that a woman has two cycles: her normal fertility cycle, and another in which peak fertility occurs at the time when the transiting solunar separation equals that in her birthchart. According to the research, a woman is most fertile when the peaks coincide; when they do not, she is relatively infertile, even at her own menstrual peak days. Independent studies have failed to confirm this theory.
