These are cells of specific types and they may be involved in the neural mechanisms that lead to ovulation. We have shown that there are profound effects of stress on the reproductive system. More importantly, we have shown that there are differences between the sexes in the way that stress affects the reproductive axis. Work is ongoing to define these sex differences. Neonatal immunocastration We have developed neonatal immunisation through the complete suppression of the reproductive system.
Work is ongoing in sheep and dogs.
A major finding is that the efficacy of the response to neonatal immunisation against gonadotrophin releasing hormone is independent of the amount of antibody generated by the immunisation. Further work will determine whether there is a sex difference in the response to the immunisation.
