While a template biopsy is recommended, it is not required in the case of MRI fusion biopsy performed on all dominant MR lesions (defined as PIRADS v2 4-5). 5. Baseline AUA symptom score ≤19 (see Appendix IV for questionnaire) without need for maximum medical therapy (specifically, not on tamsulosin 0.8mg daily) 6. EPIC sexual domain composite score 60-100 (see Appendix V) 7. Multi-parametric MRI evaluation of the prostate is required for this study within 12 months of registration.

Subjects with clinical (digital rectal examination) evidence of extraprostatic extension (T3a) or seminal vesicle involvement (T3b). MRI evidence of equivocal/potential but not definite extraprostatic extension is allowed, as long as it is unilateral and not on the side of the gland proposed for neurovascular element sparing. In equivocal cases of potential extracapsular extension on MRI only, discretion is left to the treating physician. 2. MRI evidence of gross disease (defined as PIRADS v2 score 3-5 lesions) ≤5mm of BOTH neurovascular bundles, which are the most proximate of the neurovascular elements planned for sparing on this protocol. 3. Patients with all three intermediate risk factors (PSA >10 and ≤ 20, Gleason 7, clinical stage T2b-T2c) who ALSO have ≥50% of the number of their template biopsy cores positive for cancer are ineligible. 4.

Evidence of clinical nodal involvement of the pelvis. Biopsy is required for lymph nodes over ≥1.5cm in short-axis measured size. 7. No currently active ADT or anti-androgen therapy at time of registration is allowed. Further, no more than 3 cumulative months of prior ADT or anti-androgen therapy is allowed. If either has been used by the patient, there must be a demonstration of testosterone recovery (>50ng/dL serum blood level), EPIC sexual domain score ≥60, and at least 1 month between demonstration of testosterone recovery and study registration (any one measurement of testosterone recovery suffices). 8.

Subjects who have baseline severe urinary symptoms, as defined by AUA symptom score >19 (alpha-blocker medication allowed except if taking tamsulosin 0.8mg daily at baseline which indicates compensated severe symptoms and also can affect sexual function). 13. Subjects who have a history of significant psychiatric illness that would confound informed consent. 14. Severe, active co-morbidity, defined as follows: 1. Unstable angina and/or congestive heart failure requiring hospitalization within the last 6 months 2. Myocardial infarction within the last 6 months 3.

Men who have clinically significant penile malformation (i.e. Peyronie's disease) or history of penile implantation are excluded 20. If DRE is performed, patient may not have palpable disease on side of gland to be planned for neurovascular sparing. Given the poor accuracy of DRE, such a finding should be confirmed by MRI and/or biopsy to harbor actual disease before excluding a patient
