[Artificial insemination with donor sperm. A model for the study of human reproduction]

From the experience of the CECOS French Federation concerning artificial insemination with the donor's semen (AID), a certain number of facts about the natural fecundation of couples can be deduced. The study of healthy donors constitutes and interesting biological observatory as regards the norms of the semen characteristics, the epidemiology of sexually transmissible diseases, the epidemiology of genetic abnormalities. The study of the AID results indicates that the best day for fecundation ranges between D - 3 and D + 1 (D0 being the last lowest point on the temperature curve), the rate of success varies according to the quality of the cervical mucus, the age of the woman, the length of treatment, but also to the quality of the semen (numeration, mobility, teratospermia). These results vary also in inverse ratio to the quality of the husband's semen, thus showing that the sterility problem is well a problem of the couple.
