Ischaemic priapism is the most common form of priapism and requires urgent treatment. In this study, we evaluated the effectiveness of the caverno-dorsal vein shunt on resolution of ischaemic priapism and on the post-operative long-term erectile function in patients presenting with priapism. The study included 10 patients admitted to our hospital for priapism between 2010 and 2018. ⋯ In 2 patients, severe erectile dysfunction occurred at post-operative 2 months following a priapism attack and penile prosthesis implantation was performed in these 2 patients. Our study showed that caverno-dorsal vein shunt procedure is effective in providing detumescence and maintaining potency in cases with ischaemic priapism. In our opinion, caverno-dorsal vein shunt can be considered as the first treatment of choice for refractory low-flow priapism.

Although the lack of information on the costs and pricing of healthcare services prevails throughout the medical industry, empiric observations have demonstrated that pricing information is even more obscured in the sperm cryopreservation market. Thus, the objectives of our study are to assess and compare online price transparency and the price of sperm cryopreservation across various healthcare settings in the United States. This study examined online pricing published by facilities that have an active registration to store spermatozoa with the Food and Drug Administration. ⋯ Nationally, the median initial bank fee and annual price of storage are $350 and $385 respectively. Although there were no differences in the initial fee by facility type and census region, the annual price of storing spermatozoa is highest in the Northeast, which could be attributed to laboratory techniques, demographic patterns or insurance coverage. Guidelines from professional societies or different legislation and regulatory requirements across different US states can increase price transparency, which can promote consumer decision-making and decrease the barrier for men seeking fertility preservation.

Numerous studies concentrate on the association between X-ray repair cross-complementing group 1 (XRCC1) gene polymorphism and male infertility; however, the results remain inconclusive and inconsistent. Hence, this meta-analysis was conducted to get a precise estimation of the correlation. PubMed, Web of Science, Embase, Scopus and China National Knowledge Infrastructure (CNKI) databases were searched to identify the all relevant studies before 3 May 2020. ⋯ In addition, in Asian subgroup, statistic correlation remained significant in allelic model (A-allele vs. G-allele: OR = 1.145, p = .025) with rare heterogeneity (I2 = 0%). In summary, our meta-analysis suggested that XRCC1 Arg399Gln polymorphism was significantly associated with male infertility and the A-allele might be a risk factor for this disease, especially in Asians.

We performed this systematic review to evaluate the possibility of an impact of SARS-CoV-2 infection on male fertility. SARS-CoV-2 enters the cells with the help of ACE2; therefore, testicular expression of ACE2 was analysed from transcriptome sequencing studies and our unpublished data. Literature suggested that SARS-CoV-1 (2002-2004 SARS) had a significant adverse impact on testicular architecture, suggesting a high possibility of the impact of SARS-CoV-2 as well. ⋯ We also found ACE2 expression in transcriptome sequencing data for human spermatozoa, corroborating its presence in the testicular germ cells. Transcriptome sequencing data from literature search revealed ACE2 expression in the germ, Sertoli and Leydig cells. The presence of ACE2 on almost all testicular cells and the report of a significant impact of previous SARS coronavirus on testes suggest that SARS-CoV-2 is highly likely to affect testicular tissue, semen parameters and male fertility.

Controlled Clinical Trial
Evaluation of clinical effects of microsurgical subinguinal varicocelectomy with and without testicular delivery.
The aim of this study was to access whether microsurgical subinguinal varicocelectomy (MSV) with testicular delivery has a better therapeutic effect than MSV without testicular delivery, including semen quality, serum testosterone (T) level and International Index of Erectile Function (IIEF)-5 score in infertility male patients with varicocele. In this prospective study, 181 patients were included and they chose the treatment by themselves. A total of 114 patients who received MSV without testicular delivery (TD) and 67 patients who received MSV with TD were followed-up 6 months after the operation. ⋯ But in patients with varicocele of grade III, MSV without testicular delivery improved the sperm concentration and motility more. And patients received MSV without TD have a higher T level 6 months after the operation, especially in patients ≤27 years. MSV with TD is not superior to that without, but this should be verified in more samples and a better designed randomised controlled study in the future.
