In a 2009 Ted Talk, author Mary Roach dropped the bomb that thanks to something called the Lazarus reflex, people can actually have orgasms after they die.

The Lazarus reflex, also known as the Lazarus sign, is a spinal reflex arch that happens whenever a sensory nerve is triggered in our spines. When prompted, the sensory nerve sends a signal directly to the motor nerves to move parts of our body instantly, kind of like when you jump back after stepping on a sharp object. The process completely bypasses the brain, so the Lazarus reflex can still work on someone without a functioning brain. Scientists have found they can induce movement if they touch electrodes to certain nerves on the spinal chord of a corpse.

Roach explained:

It is a fact that you can trigger spinal reflexes in dead people — a certain kind of dead person, a beating-heart cadaver. Now this is somebody who is brain-dead, legally dead… but is being kept alive on a respirator, so that their organs will be oxygenated for transplantation. Now in one of these brain-dead people, if you trigger the right spot, you will see something every now and then…

The point that triggers orgasms lies in the sacral nerve root in our spinal chords, so the same principle of the spinal reflex arch applies. Instead of prompting a cadaver to move its arm, touching an electrode to the area could stimulate an orgasm. Roach continued:

Now, if you can trigger the Lazarus reflex in a dead person, why not the orgasm reflex? I asked this question to a brain death expert, Stephanie Mann… I said, “So, could you conceivably trigger an orgasm in a dead person?” She said, “Yes, if the sacral nerve is being oxygenated, you conceivably could.” Obviously it wouldn’t be as much fun for the person. But it would be an orgasm nonetheless.

Though the science to conduct such an experiment may be available, getting the ethical go-ahead from the human subjects approval board is another story altogether.
