If you are going to use a sperm donor to get pregnant, picking someone who is already a dad seems like a good idea, right? After all, that person has a track record! Not so fast -- according to this

*Note to prospective parents -- this does not mean that you need to cross everyone off of your list who has previously gotten someone pregnant: the study suggests that it is the act of parenting which lowers testosterone levels, not the mere act of reproducing.
