Department and Faculty

Faculty member speaks with a fellow from the Andrology fellowship at Mayo Clinic in Rochester, Minnesota.

The Department of Urology at Mayo Clinic is committed to excellence in patient care, education and research. The department coordinates more than 100,000 patient care visits a year and annually performs:

  • More than 1,000 men's health procedures
  • Over 200 vasectomies and about 100 vasectomy reversals
  • Around 100 penile prostheses of varying complexities
  • About 100 fertility-related procedures (varicocele, testis biopsy)
  • Peyronie's Disease treatment including incision and grafting treatments
  • A high volume of penile doppler, xiaflex and in-office andrology procedures including Rezum prostate treatment
  • Numerous ongoing andrology-related research studies and registries

You participate in clinical care through a preceptorship model incorporating three advanced practice providers, three Men's Health nurses, and numerous others on the Men's Health team.

To facilitate research endeavors, you are granted access to pre-existing databases for penile implants, Peyronie's Disease, and fertility. In addition, faculty members have several active databases and studies.

Tobias Kohler, M.D., M.P.H.From the program director

Thank you for your interest in our one-year Andrology Fellowship! We are very proud of our previous fellows and are confident you will receive outstanding training in our program. The three program faculty members, Doctors Köhler, Ziegelmann, and Helo, have completed their own Andrology fellowships and have sub-specialty expertise. You can expect to participate in more than 100 penile implants, more than 50 vasectomy reversals (performed almost exclusively in the clinic), high volume complex Peyronie's treatment, and more than 100 BPH procedures per year. You will become independent in all aspects of andrologic surgery including clinic procedures and penile doppler. You are expected to be active academically in both publication and presentation at major meetings. Abundant opportunity for participation in original or ongoing research exists. All fellows will complete a several week microsurgery course and will be expected to help mentor residents rotating onto the Men's Health Service.

Our team looks forward to working with you.
