The source of IVF sperm
IVF means that the fertilized eggs are cultivated and transplanted into the uterus of women through in vitro fertilization technology to help those couples who cannot conceive naturally realize their reproductive dreams. The origin of IVF sperm has always been a concern. The following will elaborate on the source of IVF sperm from four aspects: donated sperm, spouse's own sperm, frozen sperm and human cloning technology.
1. Donate sperm
Donated sperm is often used in IVF treatment. In China, excellent hospitals such as the Reproductive Center of Peking Union Medical College Hospital and Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine have established semen banks, which are donated by high-quality sperm donors. Donors need to undergo strict screening and testing to ensure that they do not have any genetic diseases and sexually transmitted diseases. At the same time, the matching of different semen samples is required to meet the needs of patients. Sperm donation is an anonymous way to protect the privacy of patients and donors.
For infertile couples, sperm donation is an effective solution. However, some couples may be worried about the problem of no blood relationship with donated sperm. However, recent studies have shown that there are no significant differences in the growth, intelligence and mental health of IVF babies with different blood relationships, so the choice of sperm donation will not affect the health and growth of children.
2. Spouse's own sperm
Spouse autologous sperm refers to the sperm provided by one of the couple for IVF. This way can maintain the family genetic relationship, and avoid the possible psychological obstacles when using donated sperm. In some couples who cannot conceive naturally, they often choose artificial insemination first, and then cultivate and transplant the fertilized eggs into the female uterus through in vitro fertilization technology. In this way, the semen of the spouse needs to be checked to ensure that the sperm quality meets the standards required for in vitro fertilization.
However, for some reasons, some couples are unable to provide healthy sperm. At this time, they can only consider donating sperm or other alternatives, such as using frozen sperm or human cloning technology.
3. Frozen sperm
Frozen sperm refers to storing healthy sperm in sperm bank through freezing technology for couples with infertility and other diseases. World famous hospitals such as the Reproductive Medicine Center of Massachusetts General Hospital in the United States and the London Reproductive Center in the United Kingdom all have high-quality frozen sperm services. Frozen sperm can be stored for a long time, usually for several years, providing more choices for infertile couples.
When using frozen sperm for IVF treatment, it is necessary to thaw and treat frozen sperm to ensure that the sperm quality meets the requirements. In addition, couples need to be treated under the guidance of doctors to improve the success rate.
4. Human cloning technology
Human cloning refers to the process of reconstructing an individual in the laboratory through somatic cell nuclear transfer technology. The development of human cloning technology provides new options for couples who cannot obtain healthy sperm by other methods. Human cloning technology can transplant couples' DNA into recipient egg cells to produce test tube babies with the same genes as them. However, this technology is still controversial at the ethical and legal levels, and has not yet been widely used in IVF treatment worldwide.
In conclusion, IVF sperm can be obtained through donor sperm, spouse's own sperm, frozen sperm and human cloning technology. Under different circumstances, couples can choose the most suitable sperm source according to their own needs and doctors' suggestions to realize their reproductive dreams.
