It was his response to the law that legalised abortions in Hungary.
The method of Dr. Jonas is based on two independent cycles of fertile days in women. No medication is taken thus the method has no negative effect on the body.
It turned out that the natural conception control has a potential for further use besides contraception.
The accuracy of my calculations has been proved during 35 years and is reliable in 98% of cases, which is the maximum in the field of natural sciences and medicine.
At the moment I focus my research on calculations of the gender of the first child, which is determined already at the point of birth of the woman - future mother. The reliability is so far only 70% and therefore this type of calculations is not yet on offer.

FERTILE DAYS
Fertility is the natural ability of men and women to reproduce. Women can get pregnant and men are able to father a child like a result of unprotected sexual intercourse during fertile days of woman.
Period between two menstruations (usually in the middle of the cycle) is considered as the most appropriate time for the conception. Then supposedly the mature egg is released by the ovary where it enters the fallopian tube and continues to the womb. As it comes to the conception, the fertilized egg is able to implant to the uterine lining. If no conception occurs, the uterine lining as well as blood will be shed and the unfertilized egg will be expelled during the menstrual bleeding.
Scientists found out that certain tribes living in Africa and Asia have sexual intercourse exclusively during the time when a woman has a menstruation. And these tribes reproduce just as fast as any other people on the Earth.
Dr. Eugen Jonas argued that from the very beginning of his research, namely that the conception can happen at any time during the cycle.
Natural conception control apart the fertile days according to the period, considers another cycle of fertile days, which is based on the biorhythm that Dr. Jonas determines for each woman individually.
According to the results of the 35 years of research (1956 – 1992), 85% of the conceptions occur right during this biorhythm fertile period.
Further improvement of the method was introduction into special calculation and small calculation that offer four basic groups:
