Does open ovarian biopsy in prepubertal age affect ovarian reserve in a rat model?

Abstract

Background: Partial resection of the ovary carries a possible risk of fertility reduction. We studied the influence of open ovarian biopsy on ovarian reserve, including anti-Müllerian hormone and follicle-stimulating hormone serum level evaluation, in a prepubertal rat model. Methods: Interventionsthe initial surgery was unilateral ovarian biopsy (38 rats, group B1, B2) or unilateral ovarian biopsy and ovarian resection of the contralateral gonad (38 rats, group BR1, BR2). The second operation was bilateral ovarian resection and total resection of the remaining ovary. All rats had hormone serum levels evaluated. The control group had only a blood test taken and bilateral ovarian resection done at the second intervention (30 rats, group C1, C2). The collected tissue was examined estimating follicle count and anti-Müllerian hormone immunoexpression. Results: Anti-Müllerian hormone levels were significantly lower at the second intervention in the group BR2 but significantly higher in the group C2. Follicle-stimulating hormone levels were significantly higher in all but one group (BR2). Conclusions: Biopsy itself might not reduce ovarian reserve if done properly but we should know its possible negative effects in the case of a single remaining ovary.

Impacts of endometrioma on ovarian aging from basic science to clinical management

“…In addition, ultrasound detects AFC by identifying follicles with fluid-filled antrum, while it is limited to identify follicles in earlier stages and has difficulties in distinguishing healthy antral follicles from the ones undergoing atresia ( 27 ). The biopsy is a traumatic procedure that may decrease ovarian reserve and lead to other complications if not done properly ( 28 ). In summary, there is a lack of proper methods for assessing ovarian reserve accurately and safely.…”
