What is Priapus Toxin?

The Priapus Toxin™ Procedure is a specific method of using botulinum toxin to improve penis health & function. It has been shown in research to help erectile dysfunction (ED) for some men–even when Viagra & Cialis does not work.

How does Priapus Toxin™ procedure improve erections? 

Botulinum neurotoxin (BoNT) has been used for years as a way to relax the smooth muscle of the bladder with bladder spasm. BoNT is also thought to relax the smooth muscle that controls blood flow through the arteries of the penis; when the smooth muscle relaxes, the arteries increase in diameter, and more blood flows into the penis—causing improved erection and, perhaps, penile health.

BoNT also is known to migrate along the axon that innervates tissue (this is known to happen when BoNT is used to treat migraines). It could be that this migration of BoNT along the ganglion to the controlling axon could increases parasympathetic tone–also contributing to increased firmness of the erection.

Will the Priapus Toxin™ procedure increase the size of the penis?

The Priapus Toxin™ procedure alone is unlikely to improve the erect size of the penis (though it may help when combined with other procedures).

The Priapus Toxin™ procedure does improve the length of the flaccid penis by maintaining more blood flow in the flaccid state; this effect, in theory, could help in the recovery of the penis post prostate surgery, as well as in overall penis health.

Is the Priapus Toxin™ procedure safe?

Serious sequelae have not been seen with Priapus Toxin™. But, since Priapus Toxin™ uses botulinum neurotoxin (BoNT), and since BoNT for ED works by the same mechanism as does Viagra (relaxing the smooth muscle of the arteries in the penis), in theory, any side effect seen with either BoNT or with Viagra could happen with the BoNT procedure. For that reason, the consent form includes the same warnings included with consent for those two drugs.

How is the procedure performed?


  1. A topical medication is applied to penis for a time and then the skin is cleaned and prepped
  2. You are started on Pronox which a mixture of Nitrous Oxide and Oxygen to help with pain
  3. Multiple injections are placed in the penis
  4. You have a short recovery and can then go home
