Reproduction and ovarian ageing
British Menopause Society Journal, 2005Female fertility rates are inherently linked to a woman's age, which is in turn related to ovarian function. Reproductive potential declines gradually until 37–38 years of age, from when the rate of decline hastens. Approximately 1% of women suffer from premature ovarian ageing, and many may not have completed their families.

Ovarian Aging and Osteoporosis
2018Osteoporosis is the most common bone metabolic disease with a very high morbidity, and women usually got a higher risk of osteoporosis than men. The high incidence rate of osteoporosis in women was mainly caused by (1) women having fewer skeletons and bone mass, (2) pregnancy consuming a large amount of calcium and other nutrients, and most importantly

Aging and Ovarian Steroidogenesis in the Rat
Journal of Gerontology, 1977Ovaries obtained from rats of 4 and 18 mo of age were incubated in vitro with 3H-pregnenolone as the added precursor. Incorporation of radioactivity into progesterone (P), 20alpha-dihydroprogesterone (20alpha-P), 17alpha-hydroxyprogesterone (17alpha-OHP), androstenedione, and testosterone were studied by serial paper and thin-layer chromatography ...

Models and Biomarkers for Ovarian Ageing
2023The human ovarian reserve is defined by the number of non-growing follicles (NGFs) in the ovary, with the age-related decline in NGF population determining age at menopause for healthy women. In this chapter, the concept of ovarian reserve is explored in detail, with a sequence of models described that in principle allow any individual to be compared ...

Mutation, ageing, and ovarian cancer
The Lancet, 1997700 Vol 349 • March 8, 1997 This “epidemic” was uniformly spread throughout Sweden. All 25 regions reported an increase in 1990, except for the smallest one, Gotland (60 000 inhabitants), where the series since 1990 was ten, two, eight, ten, ten, and five cases each year to 1995.

Age contrast in ovarian pathology
Cancer, 2010BACKGROUND. Ovarian cancer accounts for approximately 23% of all gynecologic tumors and is the most common fatal gynecologic malignancy. These tumors can occur in women of all ages, but there are differences in the histologic types during various decades of life. CONCLUSIONS.
