Artificial insemination using the husband's semen (AIH) has always seemed more acceptable than the same procedure using donor semen. However, the layman may not even have thought of the legal problems or the moral dilemma if in fact a woman is inseminated using her husband's frozen semen after his death. In the USA there are already sperm banks set up by private individuals, generally for the use of those marriage partners when the husband has had a vasectomy and afterwards a child is desired. If such private sperm banks were set up in Britain complex legal problems would follow, quite apart from the moral issue as to whether it was desirable to bring a child into the world deliberately having deprived him of a father from the start. These are the issues which Mr Cusine thinks should be carefully considered before doctors, lawyers and the women potentially concerned are confronted with a new dilemma.
