Pulse rate helps identify start of fertility windows

A woman’s pulse rate could help to work out the beginning of a fertility window, a new study has indicated.

Research from Ava, a medical technology business focused on innovations in female reproductive health, discovered a substantial rise in resting pulse rate at the start of the fertile window in comparison to the menstrual phase.

This rise was an average of two beats per minute and the results could help to create new technologies to help women identify when their fertility window begins and ends. 

Ava’s own health bracelet identifies the five most fertile days of a woman’s cycle, while other available methods of tracking such as LH ovulation strips can only calculate the last 12 to 24 hours of fertility. Some also only recognise the day after ovulation when the fertility window has closed.

Resting pulse rate rises at the start of the fertile window and increases after ovulation, leading to a peak in the mid-luteal phase (when it is 3.5 beats higher than it is in the menstrual phase). 

Peter Stein, Ava co-founder and vice-president of research and development, said: “In our research, we found that resting pulse rate usually is lowest during menstruation but rises significantly five days before ovulation and again after ovulation. 

“Ava is the first technology that uses temperature, resting pulse rate, and other parameters, including heart rate variability, sleep and bioimpedance, to provide a convenient and accurate at-home method to identify the beginning of the fertile window.”

Mr Stein went on to say that we are committed to boosting the technology of women’s health tracking and improving the scientific understanding of the menstrual cycle via clinical research. 

The research was the result of two separate trials and Ava is planning to do more research in order to look at how skin temperature, contraception and other factors will influence fertility. ADNFCR-2094-ID-801835812-ADNFCR
