Nowadays, with the development of Internet, people receive news more and more frequently. In the early years, news events wanted to be published in newspapers, and people needed to call reporters to provide clues. Only after the reporter goes to interview will it be published as news. People may not know and understand the occurrence of some events so soon. Now that the Internet is so developed, besides the official media, many people have their own media or circle of friends. These are the channels through which information can be spread, which makes it more common to have twins, and people see and hear them more frequently than in previous years.
With the development of medical technology, IVF has been added to the treatment of infertility. Some people are difficult to get pregnant for some physical reasons, so they will intervene manually, such as getting pregnant by IVF. For IVF, at least two or three embryos will be implanted at a time, which is also a reason for the increased chance of twins.
With the development of science and technology and the standardization of pregnancy examination, the probability of successful delivery of pregnant women with twins has increased. In the early years, people did not have the concept of prenatal examination. For pregnant women who are pregnant with twins, there are various risks in the whole process of pregnancy, so it is very likely that some dangerous things will happen during pregnancy, which will lead to the failure to give birth to twins. Now that medical care is so developed, people are more and more standardized about pregnancy tests, and will complete the whole process of pregnancy and delivery under the guidance of doctors, which makes people who are pregnant with twins basically be able to give birth smoothly, which is also one reason why people think that the birth rate of twins is getting higher and higher.
