The study shows that symptoms of menopause can be predicted
The number of eggs in the ovaries of a woman are like grains of sand in an hourglass, clock wegtikken.
Researchers say they now are able to predict when the clock stops.
And although doctors can not really the number of eggs in an ovary, which can measure ovarian volume. British researchers say there is a direct correlation between the two, and by measuring ovarian volume with transvaginal ultrasound, the doctor should be able to predict when menopause is and how many fertile years a woman had disappeared.
The authors of the study, the information revolution in the care of women hulptechnieken, including cancer in children and women wanting to start a family, for some reason handled.
Although the information is not yet proven in clinical trials to begin distribution of more women in the treatment of cancer and women go to fertility clinics, said Tom Kelsey, co-author of the study in the journal Human Reproduction on June 17.
"If women as a kind of understanding and help you find doctors know much about menopause, you can plan for a wide range of treatments," said Kelsey, who is a member of the research, the University of St.. . Andrews, Scotland. "If you knew menopause was likely once every four or five years, plan a different set of IVF [in vitro fertilization] treatments."
Others reiterate, however, that the results should be treated with caution.
"If a young man of 30 years to pass a test to determine if three years, five or 10 for fertility, right? You have career choices and decisions about end of life? If these elements in all these decisions, "said Dr. Alan Copperman, director of reproductive medicine at Mount Sinai Medical Center in New York. The answer, of course, all these questions. The predictive value of this test is not good enough to go and tell someone's life has changed. "
According to the article, in the form of eggs from the ovaries of a woman, while still in the womb, with a maximum value of several million by mid-pregnancy and then begins a steady decline. In the East, hundreds of thousands, and when menstruation begins, about 300,000. 37 years ago, a woman of about 25,000 eggs left, and at menopause only about 1,000.
When you enter menopause, the number of eggs must be due to a lower limit.
The authors of this study, measurement of ovarian volume by transvaginal ultrasound, then looked at the relationship between ovarian volume - ovaries, a woman ages - and number of eggs. Then apply mathematical and numerical models to predict menopause.
The authors are with a medical school in the negotiations for the completion of clinical studies. The idea would be to look to women, despite their predictions correctly.
Although these writers can come from media that help women plan their lives, have warned of a second study in the same issue of Human Reproduction woman not to leave too late. Assisted reproductive technologies (ART) can not be relied upon to fully compensate for the lack of natural fertility after the age of 35 years, that section.
The authors used a computer simulation model to determine the success rate of IVF and 30 percent trying to conceive for 30 years to 24 percent are treated for 35 to 17 percent of the 40 years of age.
