Long-acting testosterone pellets, granted FDA approval in 1972, became commercially accessible in 2008 under the brand name Testopel ©. These pellets are composed of 75 mg of crystalline testosterone and are inserted into the hypovascular subcutaneous tissue (1, 2). According to FDA recommendations, the administration of 2 to 6 pellets is advised every 3 to 6 months. Testosterone levels are evaluated 1 to 4 weeks after insertion, with the guidance to add 2 pellets if the total testosterone level is below 500 ng/dl and reduce by 2 pellets if it exceeds 1000 ng/dl. Reimplantation is recommended if the total testosterone level falls below 400 ng/dl (3).

Convenience and compliance, along with a reduced risk of secondary exposure compared to gels, make this option favorable. Physician recommendations support its use. However, the high cost is often cited as a significant factor leading to patient dropout (4).

The Standard Technique (ST), also known as the "stacking method," involves stacking all pellets and inserting them into a single tract. On the other hand, the Modified V-Technique (VT) entails inserting pellets along two tracts with a 15-degree angle from the incision site.

Comparing the two techniques, the rates of pellet extrusion are significantly lower with VT at 0.8%, as opposed to ST at 7.5%. Similarly, the incidence of infection is lower with VT at 1.2%, compared to ST at 5% (5).

In this video, we demonstrated the V-technique Testopel insertion from a physician’s point of view.
