Abstract
The evaluation of ovarian reserve, often critical for the elderly infertile woman, is notoriously difficult and inaccurate. The place of ovarian biopsy in this evaluation has been hotly disputed for three decades, but not resolved. To examine the feasibility of ovarian biopsy for this purpose, a project was designed to estimate the total number of oocytes in a human ovary and investigate whether any biopsy regimen is representative of the follicular reserve in an individual. Ovaries removed from patients of reproductive age during operations not involving ovarian pathology were utilized to count the number and type of follicles found in multiple biopsies of 2 and 5 mm and in the whole ovary. Representative results taking into account the total number of follicles found in the whole ovary showed that predicted values based on the biopsies were extremely varied. We concluded that due to the huge variation in the distribution of follicles across the surface of the ovary, there is no place for this procedure in clinical evaluation of reproductive ageing in the individual patient.
