Fellowship Overview
Our one-year fellowship provides advanced clinical and surgical training inall aspects of andrology and men's sexual health. Fellows will participate in Mayo Clinic's preceptorship model, working one on one with each of the fellowship core faculty during each two-month rotation. There is some flexibilty for fellows who desire more/less exposure to certain aspects of andrology.

The Mayo Clinic Men's Health faculty performs the following:

  • Simple and complex penile implant surgery (>250/year)

  • Peyronie’s Disease treatment (including incision and grafting)

  • High volume of penile doppler, xiaflex and in-office andrology procedures (circumcision, epididymectomy, hydrocelectomy, spermatocelectomy)

  • In-office vasectomy reversal included vasoedpididymostomy (>75/year)

  • BPH surgery including Rezum and bipolar enucleation (>300/year)

  • Microsurgical varicocelectomy, microTESE, TESE (50/year)

  • More than 1,000 men’s health procedures per year

All fellows will complete a one-week hands-on microsurgery course at Mayo Clinic. It is expected that fellows will participate in clinical research and present at regional and/or national meetings. Funding adn trip days are provided by the institution for attendance at academic meetings. Fellows are not required to take call, and are allowed to moonlight.
