Decrease in testosterone in human males after birth is not news, but I've never seen anyone suggest that the cause could be decreased sexual activity as the mother heals. It is known that decreased sexual activity lowers testosterone in human males. I just had my third child 10 days ago so I'm right smack in the middle of this. I don't feel a drop in libido, but lack of sleep and the knowledge that there won't be sex for a while doesn't help. I'd like to see a study that actually proves a causal relationship here.
