"If men and women have no intention of having children, contraception is necessary during sex. However, if they want to have children, when is the most appropriate time to have them? The reproductive age of women is limited, much shorter than that of men.". So how long is the reproductive age of women? The definition of elderly women has not yet been fully unified. Some people believe that smoking women over the age of 35 should be defined as elderly women, or non smoking women over the age of 40 with normal blood pressure and weight should be defined as elderly women.
Women Don't Miss the Best Fertility Age at 35
Since the first in vitro baby was born in the UK in 1978, a recent report released by the International Committee for the Monitoring of Assisted Reproduction Technology shows that more than 5 million in vitro babies have been born worldwide. Dr. Alan Percy, chairman of the British Fertility Association and medical expert at the University of Sheffield, said he was not surprised.
The British Fertility Association, which represents British obstetricians and gynaecologists, was established in 1972. In the following 30 years, the organization grew and became a medical institution that promoted and researched the latest reproductive science achievements, clinical technology concepts, and professional training.
In the 1970s, British woman Leslie was unable to conceive naturally after nine years of marriage due to a blocked fallopian tube. Until 1976, when I learned about in vitro fertilization technology, I found Professor Patrick Steptoe and Robert Edwards. At the time, Leslie was the first person to become pregnant after undergoing a transplant operation, although other women had received fertilized eggs. She gave birth to her eldest daughter in July 1978, and four years later, she gave birth to a second daughter using this technology.
"This is an important study, and today's facts also prove that IVF is a very successful technology," said Alan Percy. Currently, approximately 1.5 million IVF or similar procedures are performed every year worldwide, and approximately 350000 IVF babies are born.
Although it was not until 2010 that Robert Edwards won the Nobel Prize in Physiology or Medicine for his achievements in IVF. But Allen believes that as IVF's social acceptance gradually increases, IVF is no longer a topic that couples are ashamed to talk about. He believes that the number of 5 million is of great significance, but what is more gratifying is that compared to the past, this technology is more accepted by people.
Allen believes that "although there are risks inherent in the medical process, the risk of IVF is very low." However, in recent years, as more and more couples around the world choose IVF, he said, "With social changes, there are more and more people marrying and having children late, which is likely to miss the optimal reproductive age under the age of 35, greatly reducing the natural fertility rate."
In addition, in the past decade, more and more British women have begun to undergo caesarean sections. According to the statistics of the British medical department, the number of women who undergo caesarean section accounts for about 30% of the total number of women. According to relevant surveys, most of the women who undergo caesarean section do not make their own decisions, but are recommended by doctors. In response, Allen said that the UK is still a country that encourages natural fertility, but it should also help young people understand scientific contraception and fertility knowledge. He also warned young couples that if they want to have children, they should try to have them before the age of 35, because "in vitro fertilization technology should be prepared for those who really need it."
How long is a woman's reproductive period
The definition of elderly women has not yet been fully unified. Some people believe that smoking women over the age of 35 should be defined as elderly women, or non smoking women over the age of 40 with normal blood pressure and weight should be defined as elderly women.
According to United Nations statistics, women over the age of 35 account for 30% of all women of childbearing age. The average woman's reproductive period is 15-49 years old. With the progress and development of society, the improvement of human health and the extension of life expectancy, women's reproductive period will also be postponed. As for the current situation, women still have about 15 years of reproductive period after the age of 35.
As for whether it is possible to have a child, whether it will affect the quality of the child (whether there are birth defects), and the risk of elderly women, there are probability issues, which are not easy to generalize.
