What is the Origin of Ovarian Attrition?

The term combines "ovarian," relating to the ovaries, with "attrition," derived from the Latin attritio, meaning a wearing down or grinding away. It is a precise term in reproductive endocrinology and gynecology to describe the genetically predetermined and continuous loss of the female germ cell pool over time.

What is the Mechanism of Ovarian Attrition?

The mechanism is characterized by a combination of apoptosis, which is programmed cell death, and atresia, which is the degeneration of ovarian follicles at various stages of development. Although only one dominant follicle typically ovulates per cycle, a large cohort begins to develop, with the vast majority of these undergoing atresia. Since the total number of primordial follicles is fixed at birth, this continuous, non-stop process, potentially exacerbated by environmental or genetic factors, dictates the rate of follicular reserve depletion.

Ovarian Attrition

Meaning

Ovarian Attrition is the irreversible, continuous, and non-replenishable process of decline in the total number of primordial follicles within the ovaries, which serves as the definitive biological clock for the female reproductive lifespan. This physiological decline commences before birth and accelerates markedly as a woman approaches the late reproductive years and perimenopause. The progressive depletion of this follicular reserve is the direct underlying cause of the cessation of menstrual cycles and the ultimate onset of menopause.
