Researchers from the Universities of Sant Andrew and Edinburgh have recently published a work that indicates that at 30 years almost 90% of the ovarian reserve of women has already disappeared, leaving only 3% at 40.
The study has been done evaluating the ovarian reserves of 325 European and American women of different ages and one of its most interesting conclusions is that some women are born with two million ovules, while others would have about 35,000, considering that the average would be 300,000 and that, although the average ovulation is about 450 times in life, the reserve drops much faster than the number of ovulations.
The decrease in the available amount of eggs decreases, according to this work, much faster than previously thought, which explains, to a large extent, the decrease in fertility from that age.
"The study shows that older women generally overestimate their chances of conceiving a child," said Hamish Wallace, co-author of the study.
Also, it is indicated that you know the ovarian reserve It would help to know previously the cases of possible early menopause and the possible need for freezing of ovules, especially in cases of late maternity or cancer patients.
