摘要：
The present invention relates to sustained release compositions, and in particular a sustained release composition comprising spermatozoa embedded in a matrix, such as a polymeric matrix. By having at least two sections with distinct dissolution rate, the matrix will ensure that spermatozoa are released for a prolonged period of time and thus making the time of insemination relative to ovulation less critical. Further, the present invention also relates to a method for preparing the sustained release composition, container comprising the sustained release composition and use of the sustained release composition in the breeding of animals.
