Postpartum vaginal atrophy affects 17.2% of women, linked to lactation. This study found a significant pH and maturation index relationship, suggesting further research into estrogen therapies.

Area of Science:

  • Gynecology
  • Reproductive Health
  • Postpartum Care

Background:

  • Postpartum vaginal atrophy is under-documented clinically.
  • Lactation is a potential contributing factor to postpartum vaginal changes.

Purpose of the Study:

  • To investigate the prevalence and characteristics of postpartum vaginal atrophy.
  • To establish the relationship between vaginal pH, maturation index, and postpartum atrophy.

Main Methods:

  • Study included 215 postpartum women at 4 weeks.
  • Evaluated vaginal pH, cytology (maturation index), and physical examination findings.
  • Excluded patients with confounding conditions like bacterial vaginosis.

Main Results:

  • 17.2% of patients exhibited vaginal atrophy with a mean pH of 6.55.

  • Control subjects (37.2%) showed normal vaginal pH (4.68) and maturation index.
  • A statistically significant correlation (p < 0.0001) was found between vaginal pH and maturation index.

    • Conclusions:

    • Postpartum vaginal atrophy is a distinct clinical entity.
    • Lactation appears to be a causal factor in postpartum vaginal atrophy.
    • Estrogen therapy efficacy requires further investigation.
