If so, that information could help predict your own fertility. Danish researchers studied over 500 women and found a correlation between hormone levels and follicle count with when their mothers started menopause:
The research team assessed the number of eggs in the women's ovaries using two accepted methods: levels of anti-Mullerian hormone and antral follicle count determined by sonography. Follicles contain the immature egg. They found that both declined faster in women whose mothers had an early menopause than in those whose mothers had a late menopause.

More research needs to be done, but I think this information could be useful to women and their doctors on how they approach any fertility issues. Do you see a correlation in your own mother and your fertility?
