Women can produce eggs continuously throughout their lives

We always assume that women only have a certain number of eggs in their lives. Therefore, current infertility treatments aim to increase conception rates in older women. However, scientists have discovered the first evidence that human ovaries can develop new adult eggs.

If this is officially confirmed, this discovery will overturn the notion that women only have a fixed number of eggs and the body is unable to increase this supply. The finding will also enhance the prospects of new treatments that allow older women to conceive and problems with infertility in young women.

In a recent study related to cancer, scientists took ovarian biopsy samples in young women who had undergone chemotherapy. And they found that these women had higher egg density than healthy women of the same age.

Professor Evelyn Telfer, head of the University of Edinburgh, said: "This is a remarkable and totally unexpected thing for us. The tissue seems to have begun to form new eggs. The previous view is that Human ovaries only have a certain number of eggs and no new eggs have been formed throughout life, there are many things we still don't know about the ovaries, so we need to be cautious when giving This finding into clinical applications ".

"I think this finding may help pave the way to developing methods for treating fertility or prolonging a woman's reproductive period by adding new follicles to the ovary , " according to Kenny Rodriguez-Wallberg, a senior consultant at Karolinska University Hospital in Stockholm.

Scientists explain that this phenomenon may be due to new eggs being formed after treating cancer or follicles divided into two or more parts due to radiation damage.

In a previous study, scientists found a way to treat ovarian failure due to chemotherapy for cancer treatment, radiation can be revived.

Research by US scientists has recently concluded that ovaries damaged by chemotherapy and radiation treatment are likely to be revived from stem cells , helping women to reproduce. normal. Research results are seen as a breakthrough and new hope for millions of female cancer patients facing the risk of being unable to be mothers due to chemotherapy.

Ovarian injury due to cancer treatment is likely to be revived from stem cells. In this study, stem cells were injected into the ovaries of the ovaries that had ovarian failure. After only a few days, the number of follicles in the ovary increased sharply, meaning the fertility of the ovaries was restored.

If the clinical trial is successful, this treatment may soon be applied to cancer patients. The lead researcher, Dr. Sara Mohamed of Mansoura University of Egypt, is also a research scholar at Georgia Regents University in the US hoping that this treatment may soon be applied in humans.
