Objective:

To examine the impact of different forms of endometriosis, specifically ovarian and deep-infiltrating subtypes, on ovarian reserve and the number of retrieved oocytes, and to identify patients who might benefit from fertility preservation through oocyte cryopreservation.

Key Findings:
  • Endometriosis affects approximately 10% of women of reproductive age and is a significant cause of infertility.
  • Women with endometriosis have a reduced monthly fecundity rate of 2–5% compared to 15–25% in healthy women.
  • Diminished ovarian reserve is particularly evident in women with ovarian endometriosis, indicated by significantly reduced AMH levels.
  • Fertility preservation through oocyte cryopreservation is recommended for women with diminished ovarian reserve due to endometriosis.
Interpretation:

The study highlights the importance of assessing endometriosis subtypes for personalized treatment and fertility preservation strategies, suggesting that tailored approaches may improve outcomes.

Limitations:
  • The study is retrospective and may be subject to selection bias, potentially affecting the generalizability of the findings.
  • Lack of globally recognized guidelines for fertility preservation in endometriosis patients limits the applicability of the results.
Conclusion:

A more detailed analysis of endometriosis subtypes is necessary to understand their differential impact on infertility and ovarian reserve, which could inform future clinical guidelines and research.
