1、 Background
With the development of science and technology, and the wide application of assisted pregnancy technology, IVF has become a choice of fertility in modern society. IVF is to breed the fertilized eggs in the laboratory to a certain stage and then transfer them to the mother to achieve pregnancy. However, because IVF involves sensitive issues such as the origin of life and family ethics, the relevant laws and policies for IVF vary from country to country.

2、 Legal Policies for IVF
1. Legality confirmation: IVF technology is legal in most countries, but not all countries allow anyone to use this technology. The laws of various countries usually stipulate the scope of application of IVF, such as whether the husband and wife are healthy and the age limit.
2. Certification of scientific research and medical institutions: IVF technology needs to be carried out in authorized medical institutions, which usually need to be recognized and supervised by the government to ensure the legality and safety of technology operation. For example, domestic Peking Union Medical College Hospital and Shanghai First Maternal and Infant Health Hospital can carry out IVF technology.
3. Informed consent of patients: IVF involves personal reproductive rights and ethical issues, so before IVF, medical personnel need to introduce the principle, risk, success rate and other information of IVF to patients in detail, and obtain clear consent from patients.
3、 Procedures for submission
1. Medical examination: Before IVF operation, patients need to carry out a series of medical examinations to ensure their physical condition and reproductive system health, including blood type and reproductive cell quality of both sides.
2. Operation procedures: IVF technology requires a series of operations, including egg retrieval, sperm collection and embryo transfer. Before the operation, the patient needs to sign the informed consent form and accept the diagnosis and guidance of the relevant doctors.
3. Legal filing: some countries require patients who have IVF to file with relevant institutions to ensure their legitimacy. These records usually need to provide relevant medical documents and personal identity information.
4、 Summary
As an assisted reproductive technology, the laws and policies of IVF vary from country to country. First, all countries have clear regulations on the technology and operating mechanism of IVF to ensure its legitimacy and safety. Secondly, patients need to receive a series of medical examinations and sign the relevant informed consent before submitting the IVF procedure. Finally, in some countries, IVF operations need to be filed to meet legal and social requirements. In general, the relevant laws and policies of IVF are intended to protect the rights and interests of patients, standardize technical operations, and provide better reproductive options for the society.
