(Patients and Methods) The study included 12 patients who underwent cRP at Kure Medical Center between August 2010 and April 2022 for diagnosis of CRPC. Perioperative outcomes, decline in serum prostate-specific antigen (PSA) levels from baseline, PSA progression-free survival, and postoperative treatment-free survival were recorded. (Results) We observed that 5 of 12 patients showed no metastases at the time of initial diagnosis, 2 had only regional lymph node metastases, and 5 had distant metastases. No patient showed identifiable metastases on imaging studies at the time of surgery. The median PSA value at the time of surgery was 0.47 ng/mL, and 5 patients had PSA values ≥1 ng/mL. All patients underwent laparoscopic cRP. Postoperative adverse events included Clavien-Dindo grade I complications in 4 and grade III complications in 1 patient; however, no patient developed rectal injury. Postoperative serum PSA levels were < 0.2 ng/mL in 8 of 12 patients (66.7%) and undetectable in 5 patients (41.7%). The median postoperative PSA progression-free survival and postoperative treatment-free survival were 12.4 and 14.5 months, respectively.

(Materials and methods) We surveyed 13 members of the Male Infertility Special Interest Group of the Japanese Society for Reproductive Medicine using Microsoft Forms. Respondents were asked about the number of new male infertility patients and surgeries at their respective facilities before the COVID-19 pandemic, after the first wave, after the sixth wave, and after the insurance changes to cover treatments for male infertility. Respondents were also asked to describe challenges in meeting the demand created by these insurance coverage changes. (Results) Patients and surgeries (varicocelectomy and testicular sperm extraction) declined markedly after the first wave of COVID-19 but gradually recovered after the sixth wave. However, once male infertility-related services were covered by insurance in Japan, respondents observed a marked increase in new patients and surgeries compared to pre-COVID-19. The most frequently reported problem was that sperm cryopreservation was not covered by insurance.
