The modern history of research originates in 1677, and is associated with the name of the inventor of the microscope Leeuwenhoek, who examined sperm and became the first to see a sperm cell. He suggested that the sperm is a seed, while the uterus creates a favorable environment for its "germination".
And in 1790, in order to overcome infertility, the famous Scottish surgeon and venereologist John Hunter injected the husband's sperm into his wife's vagina and thus carried out the first artificial insemination in the history, which successfully ended with the birth of a healthy baby. And already in the 20s of the 20th century, artificial insemination with the sperm of a husband or a specially selected donor became widely used.
Scientific and technical progress and the women's emancipation contributed to the search for new ways to solve the problem of infertility. Modern surrogacy has become possible by the advent of artificial insemination and in vitro fertilization. This also made it possible to obtain genetic material from genetic parents and then "implant" it for bearing and giving birth to a child in a natural biological incubator - the surrogate mother's body. According to relatively accurate estimates, there are 7 million people born on Earth via IVF procedures on Earth. And this is more than the population of Denmark, Norway, Finland and Uruguay. As well as joint population of Latvia, Lithuania and Estonia. It's unbelievable, isn't it?
