Background: An Asian technique of injecting collagen below the corona of the glans-the "mushroom" technique-increases the diameter of the penis glans and heightens sexual sensations for the participant and his sexual partner.
Objectives: To improve the physical and aesthetic results of the "mushroom" technique-compared with previous procedures using collagen-by using a new material and alternative injection locations and patterns.
Materials And Methods: The team used a monophasic polydensified hyaluronan (HA) gel for superficial injection into the glans of 12 men aged 28 to 61.
