Advertisement ArnimZola Answer: Oxytocin Explanation: WebThe production of oxytocin is controlled through a positive feedback mechanism. This means that the release of oxytocin causes an action which stimulates more of it to be released. For instance – when the uterus starts to contract, oxytocin is released, which in turn stimulates even more contractions, thereby causing more oxytocin to be produced.
