Serum anti-Müllerian hormone levels decrease after endometriosis surgery.

Area of Science:

• Reproductive Endocrinology
• Gynecologic Surgery

Background:

• Anti-Müllerian hormone (AMH) is a key indicator of ovarian reserve.
• Endometriosis is a common gynecologic condition affecting women of reproductive age.
• Surgical intervention for ovarian cysts in endometriosis patients may impact ovarian function.

Purpose of the Study:

• To compare post-operative serum AMH levels in patients with endometriosis versus other benign ovarian cysts.
• To investigate factors of endometriosis influencing AMH levels after surgery.
• To assess the impact of laparoscopic ovarian cystectomy on AMH levels.

Main Methods:

• Prospective recruitment of 75 patients between 2011-2012.
• Categorization into endometriosis (n=59) and other benign ovarian cyst (n=16) groups.
• Measurement and comparison of pre- and post-operative serum AMH levels.

Main Results:

• A significant decrease in AMH levels was observed post-operatively in the endometriosis group (4.3±0.4 to 2.8±0.2, p<.001).
• This AMH decline was significant regardless of endometriosis multiplicity or bilaterality.
• Patients with stage III-IV endometriosis also showed a significant AMH decrease (p<.001).

Conclusions:

• Laparoscopic ovarian cystectomy may lead to a reduction in serum AMH levels in women with endometriosis.
• Pre- and post-operative AMH evaluation is recommended for reproductive-aged women with endometriosis.
• AMH monitoring can aid in fertility preservation counseling for these patients.
