Source of IVF: How to obtain reliable embryos?
IVF technology is an assisted reproductive technology, which transfers embryos into the mother through in vitro fertilization, helping couples who cannot conceive naturally realize their reproductive dreams. However, obtaining reliable embryos is one of the keys to the success of this technology. This article will elaborate on the origin of IVF embryos from four aspects: donated embryos, frozen embryos, treated embryos and legal ways to obtain embryos.
Donate embryos
Some couples decide to donate the remaining embryos to families in need for various reasons after undergoing IVF treatment. Usually, these embryos come from surplus embryos produced during natural pregnancy or IVF treatment. Donating embryos is a selfless act that helps couples who cannot conceive naturally realize their dreams. These embryos are strictly screened and tested to ensure safety and reliable quality.
In many countries, it is legal to donate embryos. For example, Hammersmith Hospital in the UK has an embryo donation program. The plan ensures that the acquisition and distribution of embryos is carried out within a legal, transparent and regulated framework.
frozen embryo
Frozen embryos are embryos stored in liquid nitrogen for future use. These embryos can be surplus embryos that are not used in natural pregnancy or IVF treatment. Frozen embryos have many advantages, such as being able to be stored for a long time, being convenient for screening and testing, and having great cycle flexibility.
Obtaining frozen embryos requires a legal hospital or reproductive center. For example, the Reproductive Medicine Center of the University of California, San Diego, is a prestigious institution that provides couples with frozen embryos. Before obtaining frozen embryos, the hospital will carry out strict screening and testing to ensure the quality and safety of embryos.
Treated embryos
Treated embryos refer to embryos processed by a series of assisted reproductive technologies, such as embryo detection and embryo gene editing. These techniques can help couples choose healthy embryos and avoid some genetic diseases. The treated embryos have high quality and better survival rate.
The acquisition of treated embryos requires legal hospitals or reproductive centers. For example, the Reproductive Medicine Center of Peking Union Medical College Hospital in China provides embryo gene editing technology to help couples obtain healthy embryos.
Legal ways to obtain embryos
The legal ways to obtain embryos usually include natural pregnancy and IVF treatment. Natural pregnancy is the most common way for couples to conceive through natural mating. IVF treatment refers to the fertilization of sperm and eggs in vitro, and then the transfer of embryos to the mother. This treatment is usually applied to couples who are unable to conceive naturally.
The legal ways to obtain embryos also include the donation of embryos and the use of frozen embryos. These approaches are legal and regulated in many countries. Couples can choose the way suitable for their personal conditions to obtain embryos to realize their reproductive dreams.
Summary
Obtaining reliable embryos is one of the keys to the success of IVF. Donated embryos, frozen embryos and treated embryos are one of the sources of IVF embryos. However, the legal way to obtain embryos is an important factor to ensure the quality and safety of embryos. All countries have legal hospitals and reproductive centers to provide embryo acquisition services, such as Hammersmith Hospital in the UK and Peking Union Medical College Hospital in China. Couples can realize their IVF dream by choosing appropriate ways and obtaining in legal institutions.
