What is the difference between IVF and other assisted reproductive technologies?



introduction

Assisted reproductive technology is one of the achievements of the development of modern medicine, which plays an important role in helping infertile couples achieve their reproductive aspirations. As one of the common assisted reproductive technologies, IVF is different from other assisted reproductive technologies in terms of implementation methods, success rates, costs and risks.

1. Differences in technical principles and methods

Sperm donating IVF is a kind of assisted reproductive technology that realizes pregnancy by in vitro fertilization of donated sperm and female fertilized eggs in the laboratory, and then transplanting the fertilized eggs into the female uterus. Other assisted reproductive technologies, such as in vitro insemination (IUI) and in vitro fertilization embryo transfer (IVF-ET), combine the sperm and eggs of the couple in the laboratory, and then transfer the fertilized eggs into the female uterus. Compared with other technologies, IVF sperm donation is more complex, and it needs to coordinate the donation and acceptance of multiple parties to ensure the safety and legitimacy of the source of fertilized eggs. At the same time, unlike the eggs and sperm in other assisted reproductive technologies, which come from both sides of the couple, the source of fertilized eggs of IVF needs to be screened and managed more carefully.

2. Difference in success rate

In assisted reproductive technology, different methods have different success rates. According to the World Health Organization, the success rate of IVF sperm donation is relatively low, about 30% to 40%. This may be because the sperm quality of some donors is not high and the fertilization ability is poor, leading to a lower chance of fertilized eggs. The success rate of other assisted reproductive technologies such as IUI and IVF-ET is generally between 40% and 50%. Of course, each individual's situation is different, and the success rate is affected by many factors, including age, birth history, infertility reasons, etc. Therefore, when choosing appropriate assisted reproductive technology, doctors will make a comprehensive assessment based on individual conditions and provide relevant suggestions.

3. Difference between cost and risk

The relatively high cost of IVF sperm donation is mainly due to the need to screen, test and pay donors. According to the data of Peking Union Medical College Hospital, the cost of IVF sperm donation is about 150000 yuan. The cost of other assisted reproductive technologies, such as IUI and IVF-ET, is relatively low, ranging from 20000 yuan to 100000 yuan. The specific cost will vary depending on the hospital, region and individual conditions. In addition, IVF with sperm donation, like other assisted reproductive technologies, also has certain risks. Donors may transmit some genetic diseases, and the anonymity of the source of donor eggs may cause some mental distress. In addition, hormone therapy in assisted reproductive technology may cause complications, such as increased risk of multiple pregnancies.

4. Concerns about ethical and legal issues

Like other assisted reproductive technologies, IVF has aroused a series of ethical and legal concerns. The process of sperm donation involves the privacy protection of donors, the legitimacy of anonymous sperm donation, and the limitation of donation proportion. At the same time, the selection of fertilized eggs, genetic testing of embryos in pregnancy, and artificial selection of fetal sex also triggered ethical and moral thinking. In summary, there are some differences between IVF and other assisted reproductive technologies in terms of technical principles and methods, success rate, costs and risks, as well as ethical and legal issues. Doctors and couples should choose appropriate assisted reproductive technology according to the specific situation, and treat under professional guidance to achieve the desired effect.
