[AIH and AID. Review of the literature: results and observations].

The literature on homologous artificial insemination and artificial insemination by donor is reviewed. In AIH the importance of the seminal factor and the influence of the induced superovulation are taken into account in determining the success of insemination. The important factors in AIH are: the type of sperm used (fresh or frozen), the characteristics of the female recipient, the method of insemination and its timing in relation to superovulation, and unwillingness to continue therapy. In line with other studies, it is emphasised that the factors involved in insemination must be standardised and defined according to recognised statistical principles in order to allow a meaningful comparison of data reported in the literature.
