What Family Planning advise then?

Dear Sir,

It will be difficult from now on to give a correct family
planning advise based on the classical standards. What would you suggest
as an alternative? Do you think for example that automated devices which
measures two urinary hormones (and are therefore comparable to the method
you used in this research) have a better and a more reliable predictive
value than other pregnancy control menthods?
