Journal of Circadian Rhythm
Newly published peer-reviewed paper examines the relationships among circadian clocks, core body temperature (CBT), and fertility in women. Analysis of CBT via continuous recording reveals patterns in the interactions of circadian and infradian CBT rhythms capable of accurately predicting the fertility window and hormonal patterns suggesting oligo-ovulation and subfertility. New wearable technologies can facilitate employment of hormone-associated changes in CBT for pregnancy planning and offer clinical insight to infertility and menopause.
