INTRODUCTION AND AIM About 3 million men take testosterone in the United States with many reproductive-age men unaware of the negative impact of testosterone supplementation on fertility. Addressing this population, we provide an early report on the use of human chorionic gonadotropin (HCG)-based combination therapy in the treatment of a series of men with likely testosterone-related azoospermia or severe oligospermia. METHODS We retrospectively reviewed charts from two tertiary care infertility clinics to identify men presenting with azoospermia or severe oligospermia (<1 million sperm/mL) while taking exogenous testosterone. All were noted to have been placed on combination therapy, which included 3,000 units HCG subcutaneously every other day supplemented with clomiphene citrate, tamoxifen, anastrozole, or recombinant follicle-stimulating hormone (or combination) according to physician preference. MAIN OUTCOME MEASURE Clinical outcomes, including hormone values, semen analyses, and clinical pregnancies, were tracked. RESULTS Forty-nine men were included in this case series. Return of spermatogenesis for azoospermic men or improved counts for men with severe oligospermia was documented in 47 men (95.9%), with one additional man (2.1%) having a documented pregnancy without follow-up semen analysis. The average time to return of spermatogenesis was 4.6 months with a mean first density of 22.6 million/mL. There was no significant difference in recovery by type of testosterone administered or supplemental therapy. No men stopped HCG or supplemental medications because of adverse events. CONCLUSIONS We here provide an early report of the feasibility of using combination therapy with HCG and supplemental medications in treating men with testosterone-related infertility. Future discussion and studies are needed to further characterize this therapeutic approach and document the presumed improved tolerability and speed of recovery compared with unaided withdrawal of exogenous testosterone.

OBJECTIVE To determine a nationwide contemporary description of surgical Fournier gangrene (FG) and necrotizing fasciitis of the genitalia (NFG) outcomes because historically reported mortality rates for FG and NFG are based on small single-institution studies from the 1980s and the 1990s. METHODS The National Surgical Quality Improvement Program is a risk-adjusted surgical database used by nearly 400 hospitals nationwide, which tracks preoperative, intraoperative, and 30-day postoperative clinical variables. Data are extracted from patient charts by an independent surgical clinical reviewer at each hospital. Using the National Surgical Quality Improvement Program data from 2005 to 2009, we calculated 30-day mortality rates and identified preoperative factors associated with increased mortality. RESULTS A total of 650 patients were identified with surgery for FG or NFG. Fourteen patients with do not resuscitate orders placed preoperatively were excluded from analyses. For the remaining 636 patients, the overall 30-day mortality was 10.1% (64 of 636). Fifty-seven percent of patients (360 of 636) were men, 70% (446 of 636) were white, and 13% (81 of 636) were African American. Multivariate logistic regression indicated that increased age (odds ratio [OR], 1.041; P = .004), body mass index (OR, 1.045; P <.001), and preoperative white blood cell count (OR, 1.061; P = .001), and decreased platelet count (OR, 0.993; P <.001) were all associated with increased risk of death. CONCLUSION We determined a surgical mortality rate for FG-NFG of 10.1%. This rate is about half of historically published estimates and similar to recent studies. The lower rate may indicate improvements in therapy. Increased age, body mass index, and white blood cell count, and decreased platelet count were all associated with an increased risk of 30-day mortality.

OBJECTIVE To describe total and component radical prostatectomy (RP) episode costs across a diverse set of hospitals in Michigan, and examine drivers of variation in such payments. METHODS We identified Medicare and private payer patients undergoing RP from 2012 to 2014 from the claims-based registry maintained by the Michigan Value Collaborative, a statewide consortium that provides hospitals with price-standardized and risk-adjusted 90-day episode costs for common medical and surgical procedures. We divided hospitals into quartiles based on mean total episode cost for RP. Total episode costs were further classified into 4 payment categories: index hospitalization, professional services, readmissions, and postacute care. Component payments were then compared across high-cost and low-cost hospitals. RESULTS We identified 3077 patients undergoing RP in 42 hospitals. Mean 90-day total episode cost was

522, P = .002). CONCLUSION Significant variation exists in 90-day total episode costs for RP, suggesting a potential target for bundled payments and other care improvement efforts. Focused efforts on reducing variation in readmissions and postacute care could improve cost-efficiency.
