The time selection method of periodic sexual abstinence described by Knaus and Ogino is modified by this automatic measurement of the skin temperature in such a way that it offers a reliable method of contraception. The period of sexual abstinence is shortened to such an extent that this method becomes reasonable and acceptable: 5 days instead of 10 as by Knaus/Ogino. The biggest advantage is achieved if children are desired because the few hours when impregnation is possible can be optimally utilised if the time of ovulation is known exactly. Irregularities in the temperature profile are very quickly recognised and represent an excellent diagnostic aid for the treating physician. Overall, this proposed wristwatch represents an aid that enables millions of women to experience the longed-for joy of motherhood and, in addition, contributes to halting the worldwide population explosion.
