Sweden was in 1985 the first country in the world to enact legislation
concerned with the practice of donor insemination (DI). Included in t
his legislation was the requirement that information about the identit
y of the donors be kept and be made available to the resultant offspri
ng upon 'maturity', should they seek this, This provision has attracte
d much interest, debate and criticism, and claims have been made that
this has led to a decline in the numbers of men coming forward to dona
te semen in Sweden. This paper presents data covering the pre- and pos
t-legislation period from one clinic, along with the only available da
ta on all the Swedish clinics providing DI, which covers a more limite
d post-legislation period, This data shows that there has been an incr
ease in number of donors being recruited, suggesting that the possibil
ity of future contact by genetic offspring has not had the negative im
pact on the availability of donors predicted.
