Background:
Decreased ovarian function and reserve is one of the complications of hysterectomy. In this study, we aimed to compare anti-müllerian hormone (AMH) levels between total abdominal hysterectomy (TAH), and total laparoscopic hysterectomy (TLH).
Methods:
In this prospective cohort study, serum levels of AMH were compared between the groups undergoing TAH + bilateral salpingectiomy and TLH, in 66 patients (33 in each group) who referred to the hospitals of Shiraz University of Medical Sciences for hysterectomy during one years of work. The collected information included age, weight, gravidity, parity, regularity of menstrual cycle, uterine weight, blood loss during surgery, and serum levels of AMH before and 6 months after surgery, compared between groups.
Results:
Most patients (88% in TAH and 73% in TLH group) aged 40-50 years. Mean age, weight, parity of patients was similar in both groups, while blood loss was significantly less in TLH group (P < 0.01). Median (IQR) of pre-surgical AMH values were 0.40 (0.55) ng/ml in the TLH group and 0.92 (1.23) ng/ml in the TAH group (P = 0.12) that decreased to 0.29 (0.44) ng/ml in the TLH group and 0.15 (0.31) ng/ml in the TAH group (P = 0.02). Also Median (IQR) of the difference between pre and post-surgical AMH values were 0.12 (0.31) and 0.58 (1.17) in TLH and TAH group, respectively (P = 0.003).
Conclusion:
The serum levels of AMH decreased significantly after both methods of hysterectomy (laparoscopy and laparotomy), while this decrease was greater in TAH group that shows.
