Abstract: The invention provides a contraceptive vaccine for a female recipient of a target species of mammals including a composition of at least one of a plurality of granulosa cells and a plurality of ovarian stromal cells in combination with an adjuvant; wherein the cells are grown from a tissue sample of the cells obtained from at least one female donor of the target species which is not the same individual as the female recipient. The invention also provides a method of producing the contraceptive vaccine as well as a method of treating a female recipient with the contraceptive vaccine to prevent pregnancy.

Abstract: The present invention features compositions and methods for inhibiting fertility or inducing contraception in a mammal. The compositions comprise a nucleic acid molecule encoding all or part of a zona pellucida peptide. In preferred embodiments, the peptide is a zona pellucida subunit 3, especially 3a or 3b. In especially preferred embodiments, the peptide is a porcine zona pellucida. The nucleic acid can be incorporated into an expression vector. The methods for inhibiting fertility or inducing contraception in a mammal comprise the step of administering a nucleic acid molecule encoding all or part of a zona pellucida peptide.
