Lunar birth control is a natural fertility awareness method based on the idea that a woman’s fertility is influenced not only by her menstrual cycle but also by the phases of the moon. Originating from the work of Dr. Eugen Jonas in the 1950s, this theory suggests that a woman’s most fertile days are just 2-3 days before the moon is at the same Soli-Lunar phase as it was at her birth, regardless of when this date falls in the menstrual cycle.
The Soli-Lunar phase refers to the aspect or angle between the Sun (Soli) and Moon (Lunar) at the moment of birth. So, for example, if a woman was born at the full moon (sun and moon opposite each other in the zodiac) she would be more fertile in the 2-3 days before the full moon. And if she was born at the new moon (sun and moon in the same sign of the zodiac) she would be more fertile in the 2-3 days before the new moon, each month.
According to this method, two fertility windows exist: the biological/physical (ovulation) and the lunar (moon phase). This dual approach can be used to either prevent or plan pregnancy without hormonal contraceptives. (Disclaimer: Lunar birth control is not scientifically validated and should not be relied upon as a sole method of contraception without further medical support or backup protection.)
