What is an embryo? After fertilization, the male germ cell spermatozoa and female germ cell eggs are fertilized and further divide and grow rapidly in the form of 1 to 2 and 2 to 4, until they are implanted into the maternal endometrium on the 5th-6th day after fertilization, and develop until the organ-tissue differentiation is basically completed at 12 weeks. In assisted reproductive technology, sperm-egg, post-fertilization embryos can be artificially cultured, screened, frozen and thawed until the 5th-6th day of fertilization. Frozen embryos stop their life activity at -196 degrees Celsius and can continue to grow after thawing. In scientific research, embryos within 14 days of fertilization can be used for research such as embryonic stem cell research. Do embryos have any rights? This question needs to be answered in the context of a particular country, religion or culture. According to our laws and general ethical standards, a legal couple can decide to transfer embryos to have a child under the family planning policy, or they can discard or donate them for research or freeze them. There are no additional rigid rules regarding the age of the couple or the duration of preservation. The pregnant mother can also initiate a termination of pregnancy at the embryonic stage after conception. The embryo does not have any established rights, i.e., if the couple never comes to care for their embryo again, or if they request a termination of pregnancy, it cannot constitute any crime similar to the crime of abandonment. In some countries, the fertilized egg is considered to be a living entity from the time of oogenesis, so the law requires that only single-celled fertilized eggs of the syngeneic stage can be frozen and preserved; in some countries, embryos can be donated directly to another couple with the couple’s permission to have a child, and the custody of the child belongs to the couple who receives the donation. In other countries, the parents of embryos fertilized more than 10 years ago may be too old to raise a young child and may not be able to do so. The legal prohibition of aborted fetuses is in force in most foreign countries. As can be seen, compared to regulations in countries around the world, our current regulations emphasize family planning policies and the reproductive rights of couples, with relative neglect of the dignity of potential life and the protection of offspring. With the expansion of assisted reproductive technology now underway, the number of people exposed to this special situation has increased, and the corresponding socio-human legal issues have gradually surfaced. Because it is a weighty issue involving life, we hope that the national government and relevant multidisciplinary experts will give guidance as soon as possible. We also believe that in the future, people will be more rational, responsible and compassionate in dealing with fertility issues and these small but infinite possibilities of embryos.
