Laparoscopic surgeries for uterine fibroids and ovarian cysts reduce ovarian reserve via age- and surgical type-manner.

Aim: Diminished ovarian reserve can be characterized by poor response to ovulation and low number of eggs. The risk factors include endometriosis, receiving cancer treatment, luteal phase deficiency and gynecologic surgery. Uterine fibroids and ovarian cysts are the most common benign gynecological diseases in women globally. This prospective study evaluated the influence of laparoscopic surgery treating benign gynecological diseases on ovarian reserve.

Methods

A total of 121 patients with uterine fibroids or benign ovarian cysts who received laparoscopic surgeries (41 with hysterectomy, 36 with myomectomy, 18 with adnexectomy, and 26 with ovarian cystectomy) were included. The ovarian reserve status defined as serum anti-Mullerian hormone concentration was assessed at 1 month before and after surgery, respectively.

Results

The anti-Mullerian hormone reduction level was 22.34% in cystectomy, 44.1% in adnexectomy, 24.92% in myomectomy, and 47.61% in hysterectomy (p < 0.001). Multivariate analysis showed that adnexectomy had significantly high risk of high serum anti-Mullerian hormone reduction level (adjusted odds ratio (aOR): 14.90, 95% confidence interval (CI): 2.56-86.93, p = 0.003).

Conclusions

These 4 laparoscopic surgeries all reduced the AMH levels 1 month after the procedure. Further prospective studies with longer follow-up are necessary to know the real impact on the ovarian reserve. Adnexectomy was an independent factor of reduced ovarian reserve in 1 month after surgery.
