PIP: A study is reported of 966 women, average age 28 years and 9 months, who used the basal temperature control method as the only means of contraception for a total of 59,566 menstrual cycles. 2 methods of temperature control were used. For the ''strict'' method, the ''safe period'' begins the 3rd day after the temperature increase and continues until the next menstruation. The ''combination'' method adds to this ''safe period'' another period which begins with the menstruation and continues to the 6th day before the earliest recorded temperature increase of a series of menstrual cycles. 307 women (11,325 cycles) used the ''strict'' method, with a Pearl index of .8 pregnancies/100 woman-years. 689 women (48,214 cycles) used the ''combined'' method, with a Pearl index of 3.1 pregnancies/100 woman-years. Some natural drawbacks of this method are that infection can cause premature temperature increase, and the ovulation cycle may be irregular naturally or because of medication. 61 of the pregnancies occurred due to intercourse during the fertile period and 40 because of incompletely taken temperature measurements. These apparent patient errors must be considered method failures due to the nature of the method. This contraceptive method is considered an excellent one since it is generally acceptable and agreeable and shows an acceptable degree of efficency.
