It is now 110 years since the first reported medical use of donor insemination. Despite its somewhat doubtful beginnings and its chequered history, especially up until the 1970s, DI has become a well accepted and utilised part of most infertility treatment services. An American survey in 1988 reported that approximately 80,000 women a year undergo the procedure, and that over 30,000 children are born each year. The only figures from the United Kingdom cover a 5-month period between August 1 and (...) December 31, 1991, and show that 4,260 patients were treated with DI during this period. The treatment was carried out in 85 different centres. (shrink)
