Can IVF technology increase the probability of twins?
IVF, also known as in vitro fertilization (IVF), is an assisted reproductive technology that can help couples or individuals who cannot conceive naturally realize their reproductive dreams. In recent years, some people have questioned whether IVF technology can increase the probability of twins. This article will elaborate on this from many aspects.

Research Report of the Medical Center of the University of Bhutan in the Netherlands
According to the research report of the Medical Center of the University of Bhutan in the Netherlands, IVF technology can increase the probability of twins to some extent. This study selected 1000 cases of IVF for investigation, and found that about 25% of IVF babies are twins, while in the case of natural pregnancy, the proportion of twins is only about 2% to 3%. This result shows that IVF technology can significantly increase the probability of twins.
However, it is worth noting that this phenomenon of increasing the probability of twins is mainly due to the fact that multiple fertilized eggs are often transplanted during IVF. With the development of technology and the improvement of doctors' operation, more doctors now choose single embryo transfer to reduce the incidence of twins, because twin pregnancy has a higher risk.
Twins in IVF
The twin phenomenon in IVF mainly comes from the following two reasons. First, in order to improve the success rate, doctors will transplant multiple fertilized eggs in the IVF program. Secondly, because female patients may have abnormal ovulation or other reproductive system problems, transplanting multiple fertilized eggs can increase the chances of successful implantation of fertilized eggs.
However, multiple pregnancy also brings a series of risks, including premature delivery, low birth weight, maternal complications, etc. In order to reduce these risks, many doctors now prefer to choose single embryo transfer to ensure the health of mothers and babies.
Hospital praises single embryo transfer policy
Some hospitals have begun to promote the single embryo transfer policy to reduce the twin rate. For example, the Harry Street Clinic in the UK has significantly reduced the twin birth rate in the past decade. They actively promote the advantages of single embryo transfer, educate patients about the risks of multiple pregnancy, and provide better solutions through more accurate embryo selection and freezing technology.
This single embryo transfer policy is a safer and preferable choice for those healthy patients or couples who only want to welcome a single child. For those couples who wish to have twins, they can keep the remaining embryos during the freezing process so that they can try to transfer them again later. This method not only satisfies the dream of childbirth, but also reduces the risk of mother and baby.
summary
In conclusion, IVF technology has increased the probability of twins to a certain extent. However, with the progress of technology and doctors' more attention to risks, more and more doctors and hospitals now choose single embryo transfer to reduce the incidence of twins and provide safer birth choices. Therefore, whether IVF technology can increase the probability of twins depends ultimately on the choice of doctors and patients.
