About Dullness Syndrome (DS)

Urologists report a broad spectrum of patients with varying degrees of reduced sensation in the glans. The degree of dullness can range from slight impairment to near total loss of feeling.

For such patients, CIRCUMserum may be indicated as a first line solution, to assess whether regular moisturization of the skin on the glans will help promote reflexogenic action in maintaining erection and triggering orgasm.
