<jats:title>Abstract</jats:title><jats:p>The maintenance of genetic diversity in captive populations is a primary goal of captive breeding plans, and it is becoming increasingly apparent that reproductive technology has much to offer captive breeding programs in attaining this goal. Reproductive technology can best assist captive breeding programs in this task by developing strategies that effectively increase the genetic contribution of new wild founders to a population as well as increase the reproductive life span of existing founders and their close descendents. This will act to reduce genetic drift and inbreeding effects in the population and thereby minimize the loss of genetic diversity.</jats:p><jats:p>Considering only one aspect of reproductive technology, semen collection, this paper examines some of the genetic considerations that might be used for choosing which males in a population to collect semen from, assuming the goal of the captive breeding program is the preservation of genetic diversity. It is shown that semen collection and preservation, with future intent of artificial insemination, can make significant contributions to the maintenance of genetic diversity if careful consideration is given to the selection of donor males. Finally, the pedigree of the captive population of Asian lions (<jats:italic>Panthera leo persica</jats:italic>) is used to illustrate some of these genetic concepts that might be important in selecting males as semen donors.</jats:p>
