Endometrioma Related Reduced Ovarian Reserve (ERROR)

December 16, 2017 updated by: GÜRKAN UNCU,PROF. MD, Uludag University

The Effect Of The Presence Of Endometriomas On Ovarian Reserve

Prior studies have shown surgical excision of endometriomas are associated with a decline in ovarian reserve as assessed by serum anti-Mullerian Hormone (AMH) levels. However, the natural history of serum AMH levels in the presence of untreated endometriomas are unknown. Purpose of this study is to determine whether the presence of endometriomas cause a faster decline in serum AMH levels than in healthy women over a six months period.

Detailed Description

The study is a prospective cohort study. Women diagnosed with endometriomas by transvaginal or transabdominal ultrasound or MRI will be recruited from a tertiary care endometriosis clinic. Age matched healthy controls will be recruited from the staff of the same hospital. A priorly published historical group of women who underwent endometrioma excision will be a second comparator.

Probability Sample

Study Population

The decision to include a healthy control group was taken five months after starting recruitment of women with endometrioma. Only 12 women with endometriomas had been recruited until then and none of them had six month serum AMH level measured.

Since healthy controls were reluctant to undergo transvaginal ultrasound examination, antral follicle counts were not measured as another marker of ovarian reserve for healthy controls and some women in the endometrioma group.

Description

Inclusion Criteria:

  • Reproductive age
  • Endometrioma without indication for surgery or treatment with combined contraceptive, progestin or other hormonal intervention.

Exclusion Criteria:

  • Menstrual cycle irregularity
  • Polycystic ovarian syndrome
  • Women who were pregnant or contemplating pregnancy in the next six months
  • History of ovarian surgery
  • Using medication which could affect ovarian function during six months before recruitment
  • Indication for surgical excision

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Endometrioma
Reproductive aged women diagnosed with endometrioma. Conservative follow up for six months.
Other: Conservative follow up
Healthy Controls

Women with regular menstrual cycles and without ovarian pathology will be recruited from physicians, nurses and other staff of the same hospital.

Controls will be matched for age with the women in the endometrioma group. They will be conservatively followed up for six months.
Other: Conservative follow up
Historical controls who underwent surgical excision
20 women who underwent surgical excision of endometrioma in the same clinic had serum AMH levels measured preoperatively and on post operative sixth month. Their values will be compared with that of endometrioma group. These data were priorly published in detail (Uncu et al. 2013).
Procedure: laparoscopic endometrioma excision
