Again, review human nature.
The man and woman face different incentives. The women talked about in the article are getting pregnant because they WANT to get pregnant, out of wedlock, in order to be able to demand child support from a wealthy father. If your objective is to reduce out of wedlock pregnancies, the way to do it is to eliminate women's incentives to get pregnant.
You will not change behavior unless you change desires.
Women cannot get pregnant on their own.
The men in the article at least understand their biological role in procreation and are taking personal responsibility to prevent a biological event from happening. That to me is much better than people who want to cling to double standards of sexual responsibility.
