Sex Differences in the Effects of Etonogestrel on Respiratory Recovery in an In Vivo Rat Model of Central Chemoreflex Impairment

Key Points

• The research aims to investigate the influence of sex on the effects of etonogestrel on respiratory recovery in rats with central chemoreflex impairment.
• Utilized an in vivo rat model to assess respiratory recovery
• Administered etonogestrel (ETO) to evaluate its effects
• Compared recovery outcomes between male and female rats
• Male rats did not exhibit significant recovery with ETO treatment
• Female rats showed improved respiratory recovery with ETO
• Suggests a sex-specific mechanism in chemoreflex recovery
