Ovarian ageing and the menopausal transition

Best Practice & Research Clinical Obstetrics & Gynaecology, 2002
The underlying cause of the menopausal transition is a dwindling supply of FSH-responsive follicles available for ovulation. Additional factors may include dysregulation of existing follicles and concurrent follicle and oocyte deficits that may be strictly anatomic or consequences of the hormonal milieu.

Reproductive aging and ovarian volume

International Journal of Gynecology & Obstetrics, 2005
Ovarian volume measurements were first used in ovarian cancer screening. However although the effect of menopause on ovarian size has been demonstrated little and conflicting information was available regarding women of reproductive age. For some authors there was an inverse correlation between age and ovarian size for others there was no such ...

Ovarian aging

Current Opinion in Obstetrics & Gynecology, 2011
In the past few decades, women have been intentionally delaying pregnancy and ovarian aging has become one of the most detrimental factors of pregnancy achievement. This review will discuss contemporary methods of ovarian aging assessment and present an overview of current management strategies.Antimullerian hormone (AMH) and antral follicle count (AFC)

Strategies for Controlled Ovarian Stimulation in the Setting of Ovarian Aging

Seminars in Reproductive Medicine, 2015
In the context of assisted reproduction, the term ovarian aging is often used to refer to declining potential of ovaries to produce oocytes in adequate number or quality in response to controlled ovarian stimulation (COS). Different aspects of COS have been modified with the intention to increase the number and quality of oocytes obtained for in vitro ...

Early ovarian ageing

The Obstetrician & Gynaecologist, 2019
Key content Early ovarian ageing (EOA) affects around 10% of women. Women with early ovarian ageing are frequently asymptomatic with normal fertility; however, continuing follicular loss will result in loss of fertility, menstrual irregularity and, finally, early menopause.

Ovarian Aging and Reproduction

2023
The ovary plays a very significant role in aging. The regenerative capacity of stem cells is the key factor to promote healthy aging, and the stem cell viability would decline sharply after the reproductive period, especially in women. Except for stem cell aging and neuroendocrine aging, ovarian aging is also a hotspot in the field of aging research ...

Is ovarian ageing inexorable?

2009
The total number of oocytes (follicles) declines continuously after birth such that, by the time of menarche, only a quarter of a million follicles remains, or even fewer in girls prone to premature ovarian failure. In this chapter, attention has been drawn to ovarian ageing as an inexorable process, which has sometimes been simplistically compared to ...
