Abstract
Summary An analysis has been made of the results of an artificial insemination by donor (A.I.D.) programme within the National Health Service, to identify social and biological factors which may be used in the prognosis of patients entering such a programme. Patients were separated into a group which conceived and a group which had not conceived but were continuing to receive A.I.D. treatment. It was found that conception was favoured if the patient was in social classes I and II, or was in the youngest age range, 20–25 years old, and did not need drugs to stimulate ovulation. Conception was not affected by the presentation of a temperature chart or by the patient being in employment. The outcome of the conceptions is also presented. The number of female babies born was greater than the number of male babies; the ratio of sexes differed from that expected with normal conception. It was concluded that most of the conceptions had resulted from inseminations before the basal temperature fall.
