What is PERIMON?

For whom is PERIMON?

PERIMON is made for women from 18 to 45 years, who ...
- are interested in simple and time-effective natural birth control,
- appreciate an open system that can be modulated to their individual needs,
- want to perceive the various cyclic changes in their body

What is the difference between PERIMON and other cycle calendars?

To optimise its forecasts PERIMON calculates - in contrast to many other products - your actual cycle length and ovulation date. Furthermore PERIMON was designed with the focal point on safety. Whereas many other calendars only display statistical fertility values or designate too many days as infertile by default, PERIMON's fertility data are based upon the analysis of your individual cycle

Is birth control with PERIMON safe?

It is. If you use PERIMON only with the rhythm method, we estimate the Pearl index to 4.0 (a good safety). If you additionally examine your mucus or cervix - which is easy to do - safety will increase up to 1.0 (details on our web site)

What is the disadvantage of PERIMON?

PERIMON only designates max. 10.5 days per cycle as infertile and it needs ca. 3-8 cycles before it starts with a prediction. These are the limitations of the rhythm method that can be broadened yet, as already mentioned above, by applying e.g. the cervical mucus observation (whenever required).
