The percentages apply to all women whose ovarian reserve declines in line with a particular model where late and early menopause are associated with high and low peak NGF populations, respectively. It is estimated that for 95% of women by the age of 30 years only 12% of their maximum pre-birth NGF population is present and by the age of 40 ...
Menopause typically occurs between 44 and 58 years of age. [8] DNA testing is rarely carried out to confirm claims of maternity at advanced ages, but in one large study, among 12,549 African and Middle Eastern immigrant mothers, confirmed by DNA testing, only two mothers were found to be older than fifty; the oldest mother being 52.1 years at conception (and the youngest mother 10.7 years old).

By her late 40s, Weber was experiencing symptoms of perimenopause, including the occasional missed period. Assuming she was no longer fertile, she went off birth control.
By virtue of the "inefficient" nature of folliculogenesis (discussed later), only 400–500 of these follicles will ever reach the preovulatory stage. At menopause, only 1,000 follicles remain. It seems likely that early menopause occurs for women with low populations at birth, and late menopause occurs for women with high populations at birth ...
It's a common question, but Dr. Batur says it can be challenging to provide a hard-and-fast answer as to when you'll know the end of perimenopause is near. "You only know that you're in menopause ...
About 95 out of 100 couples who are trying to get pregnant do so within two years. [90] Women become less fertile as they get older. For women aged 35, about 94% who have regular unprotected sexual intercourse get pregnant after three years of trying. For women aged 38, however, only about 77%. The effect of age upon men's fertility is less ...
