Dr. Abraham Morgentaler

I wanted to be a good surgeon and I wanted to learn how to treat all these different things. I started off in male infertility and male sexual issues. And part of the reason I picked that was there were some new procedures for sexual dysfunction that required microsurgery or they were just interesting cases. So, you know, arterial bypasses for erectile dysfunction. We hardly do these anymore.

But that was exciting back then. And so I started seeing some men who had ED or decreased libido, and they were desperate, some of them. And this was 10 years before Viagra would show up. And so a couple of these men would say to me, don't you have anything, doctor, that you can help me with? My wife's going to leave me or my girlfriend is really unhappy with me.

And as an undergraduate at Harvard, I had worked in a laboratory for three years with lizards, the kind that you find in Florida and in the Carolinas, the little guys that are everywhere. And the experiments involved testosterone. And my project was to put testosterone into the brains of these males.

If you castrate a male lizard and you put him in a cage with the female, normally if they're not castrated, they have this whole sexual behavior. They've got this bright flap of skin that comes out. The head bobs up and down quickly and they mate. And if you castrate them, you put them in the cage, they don't do anything. They don't care. They have no libido.

and my project we had mapped out where in the brain testosterone was taken up and we knew which of those areas were likely to be the sexual centers and i had a my project was to figure out a way to put little testosterone implants tiny tiny tiny into the sexual centers of their brain and when i was successful and it took a few years to figure this all out even though the male had no circulating testosterone that we could detect

The male would see the female, and the flap of skin would come out, head would bob up and down, and they would mate. It restored all their sexual behavior. It was incredible. And what I learned from that was that testosterone was, amongst other things, a brain hormone. It worked in the brain, and it was enough to regulate the entire sexual repertoire of these lizards.

The deep part of our brain that's also involved with sexual behavior, we still call the reptilian portion of our brain. And we call it that because some of the old parts of the brain are conserved. You know, the processes are identical or almost identical, going back to earlier vertebrates in evolution, like the reptiles.
