چکیده

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.

I-32: Management of Diminished Ovarian Reserve

The standard goal of all fertility treatments is the improvement of pregnancy rates in infertile patients. Within the last 20 years, ovulation induction has contributed to the success of assisted reproduction techniques e.g. in vitro fertilization (IVF) and embryo-transfer (ET). The efficacy of these techniques depends on a personalized protocol of controlled ovarian hyperstimulation (COH) and ...

Background: Immaturity of the ovarian follicles results in an infertility citation called Premature Ovarian Failure (POF), affecting approximately 1% of women under the age of 40. Women with this disorder go through early menopause and have high levels of gonadotropin hormones (FSH & LH). Diminished Ovarian Reserve (DOR) is another infertility disorder in which women’s ovaries have the ability ...

Is There any Mean to Postpone The Menopausal Ovarian Senescence?

The ovarian reserve (OR) gradually decreases throughout the female fertile life. This continuous depletion in OR is irreversible. This occurs through a programmed cell death known apoptosis. Some factors hasten such depletion such as chemo- and radiotherapy. Others have been investigated in trials to preserve the OR including gonadotropins, cytokines, growth hormones, nitric oxide and reorganiz...
