The duration of pregnancy post ovulationem (p.o.), post hyperthermiam (p.h.), and post menstruationem (p.m.) was calculated for single births with birth weights around 2,500 g against the background of basal temperatures which had been measured by 172 patients. - Average pregnancy durations, p.o. (n = 159) were 263 +/- 11,3 days [boys (n = 81) 262,2 +/- 12,3 days; girls (n = 78) 263,9 +/- 10,1 days]. Average pregnancy durations, p.h. (n = 171) were 260,4 +/- 11,5 days [boys (n = 90) 259,7 +/- 12,2 days; girls (n = 81) 261,2 +/- 10.8 days]. Differences for p.o. and p.h. mean values between girls and boys could not be statistically secured. The average duration of pregnancy, p.m. (n = 166) was 281,7 +/- 11,2 days, with boys being born (n = 89) after 280,8 +/- 12,4 days and girls (n = 77) after 282,7 +/- 9,7 days.
