|December 27, 1974
Summary
Volatile aliphatic acids in vaginal samples fluctuate with the menstrual cycle, increasing in the follicular phase and decreasing in the luteal phase. Oral contraceptive use alters these acid levels and eliminates cyclical changes.
Area of Science:
- Reproductive biology
- Human physiology
- Analytical chemistry
Background:
- Vaginal volatile compounds play a role in reproductive processes.
- Menstrual cycle phases are associated with physiological changes.
- Aliphatic acids are known to have biological functions.
Purpose of the Study:
- To investigate the cyclical changes of volatile aliphatic acids during the human menstrual cycle.
- To determine the effect of oral contraceptives on vaginal volatile acid levels.
Main Methods:
- Collection of vaginal samples from 50 healthy women using a tampon method.
- Analysis of volatile aliphatic acids via gas chromatography.
Main Results:
- Volatile aliphatic acids showed a distinct pattern, increasing during the late follicular phase and decreasing throughout the luteal phase.
- Women using oral contraceptives exhibited lower concentrations of these acids.
- Oral contraceptive users did not display the rhythmic changes observed in non-users.
Conclusions:
- Vaginal volatile aliphatic acid levels are subject to cyclical changes related to the menstrual cycle.
- Oral contraceptive use significantly impacts the concentration and cyclical variation of these compounds.
- These findings contribute to understanding the biochemical milieu of the human vagina and its potential signaling roles.
