The menstrual cycle influences carbon dioxide (CO2) sensitivity in women. CO2 sensitivity significantly increases during the luteal phase, likely due to progesterone.

Area of Science:

  • Physiology
  • Reproductive Biology
  • Respiratory Control

Background:

  • Carbon dioxide (CO2) sensitivity is a key regulator of breathing.
  • The influence of the menstrual cycle on respiratory control remains incompletely understood.

Purpose of the Study:

  • To investigate the impact of the menstrual cycle on resting CO2 sensitivity in women.
  • To determine if hormonal fluctuations during the cycle alter ventilatory responses to CO2.

Main Methods:

  • 20 regularly menstruating females participated in the study.
  • CO2 sensitivity and threshold were measured using CO2-rebreathing tests over 6 weeks.
  • The menstrual cycle was divided into three phases (follicular, luteal, menstrual) based on oral temperature.

Main Results:

  • A significant increase in CO2 sensitivity was observed between the follicular and luteal phases.
  • A significant decrease in CO2 sensitivity occurred between the luteal and menstrual phases.
  • No significant difference in CO2 sensitivity was found between the follicular and menstrual phases. CO2 threshold remained unchanged.

Conclusions:

  • Progesterone, elevated during the luteal phase, is likely responsible for the increased CO2 sensitivity.
  • The menstrual cycle significantly modulates resting CO2 sensitivity in women.
  • CO2 threshold is not affected by the menstrual cycle phase.
