A question of trust?

The news that a male contraceptive jab is being trialled has lead to the usual suspects declaring that women cannot 'trust' men to have the injection as it the woman who ends up carrying the baby. Oddly these women, for they are usually women, do not ever ask if men can trust women to take the contraceptive pill. It is as if these people have never heard of men being 'oopsed' and tricked into fatherhood. If a couple don't want to have children then I would say that both using reliable contraception can only be a good idea.
