There are 20 years since the title “Artificial Insemination dynamics and prognosis in cattle” was the presented thesis by me as a graduate student. A 20 years period is long enough to find out if the dynamics and the prognosis were true. That time Artificial Insemination was appreciated as a strong mean to prevent venereal diseases, and to increase bulls’ fertility. It was also seen as a needed biotechnical in ET technology. From the scientifically point of view spermatozoa sexing was then preview the term of fertilization ability of sperms being fully satisfied. In breeding practice AI was seen as a very efficient mean to induce genetic progress using progeny tested sires and ET as short term way to transfer breeds of interest to new areas. It was considered AI mostly will be applied in dairy breed where all active populations will be reproduced by artificial insemination. In extensive systems of beef cattle farming AI will be few extended because of too much labor needed. For Romania AI has to be extended since the action continued to be sustained by the public finance that paid the deep frozen semen used by cow owners. They had to pay inoculation of semen only.Excepting the last prognosis all other of them fulfilled. But AI association to the other biotechnologies development has shown richer than it was then specified. In the present form progresses in biotechnologies AI assisted will be more discussed. Sperm sexing, MOET, IVF, Embryo sexing, artificial identical twins genesis, Mammal animal clone production and engineering of transgenic organisms are mentioned in relation with new organism genesis and their security food or economic importance.
