Much of my practice is men's health, and after twenty years and thousands of minimally invasive procedures, I plan this one the same way: your goal first, then the volume, then precise placement.

About the Procedure

What Is Upsize™?

Upsize™ is a physician-led penis enlargement procedure using hyaluronic acid dermal filler. The in-office treatment typically takes under an hour, requires no surgery or implants, and involves no downtime.

Unlike pills, pumps, or surgical penis enlargement with weeks of recovery and downtime, penis enlargement injections deliver immediate, visible results you can see before leaving the office. This is typical; your provider evaluates what is right for you, case by case, at your appointment.

Plus Firm-X™ — Penile Neuromodulator

Firm-X™ is Upsize™'s penile neuromodulator procedure — a single in-office injection that improves erectile firmness and increases flaccid hang for about 6 months per treatment. Takes about 20 minutes, no downtime, often performed in the same visit as penis enlargement injections.

Fat Transfer vs. HA Fillers for Penis Enhancement: Complete Comparison

A detailed comparison of fat transfer versus hyaluronic acid fillers for penile girth enhancement—examining results, longevity, complications, and which approach produces better outcomes. Fat transfer (also called lipofilling or fat grafting) and hyaluronic acid fillers represent two fundamentally different approaches to penis girth enhancement. Both add volume beneath the penile skin, but they use different materials and produce different results.

Firm-X: How Penile Botox Improves Size, Firmness & Performance

Every man has experienced it: the penis that shrinks dramatically in response to cold water, stress, anxiety, or simply without apparent reason. This retraction is controlled by the dartos muscle—smooth muscle tissue in the penile shaft and scrotum that contracts involuntarily.
