Many women are delaying getting married without conscious egg cells decline rapidly. Research ovary from birth to menopause at age 30 showed that women only 3% of egg cells at birth.
Women should not delay the married since birth time is only limited.
According to a new study, the biological clock ringing woman aged 30. This is the first study to emphasize the risk of infertility in women due to the severe decline of ovarian reserve.
The rapid decline of ovarian reserve and fertility has been known before. But this study was conducted throughout the process, from its inception until late childbearing, rather than notice of the specific age group.
According to researchers from the University of Edinburgh, Dr Hamish Wallace, the results of this study did not endorse the theory that the ovaries contain stem cells can produce more eggs. Number of eggs is fixed from birth.
Rapid decrease
The researchers said the average age of 30, women will only remains 12% - about one eighth of the egg cell.
By age 40, the poor availability when only maintain 3% of the total 2 million egg cells, but the women initially.
Only about 450 of the 2 million egg cells to mature fully in the life of women. The others only started nine before the target variable.
Women more eggs, cooked eggs advantages will be more up to help women become pregnant easily.
Researcher Dr Tom Kelsey Andrews University, said the women are always waiting for promotion or a party army lang satisfactory. But they are not aware that ovarian reserve severely reduced after the age of 35. Each year passed, they lose a large proportion of ovarian reserve. About age 45, many women begin menopause.
Toward women cancer
Working with the University of Edinburgh expert, Dr. Kelsey counting eggs in the ovaries of 325 women in the age difference.
Information is transferred into the program computer to learn ovarian decline over time.
The analysis is posted on the newspaper PLoS ONE shows that until age 25, the agent as smoking or drinking does not significantly affect the fertility of women. But soon after this time, the women take care of itself have a significant impact to their birth.
Unlock the way the biological clock may help doctors give better advice to young cancer patients to preserve their fertility.
If doctors can map out any precise ratio of ovarian likely destroyed by the method of radiotherapy or chemotherapy, can be calculated when patients begin to suggest their menopause time should be con.
Dr Hamish Wallace said in some cases, children the best chance of the patient was due to freeze eggs or application of treatment methods for ovarian.
