Long-term benefit of male circumcision to the reduction of urinary tract infections and genitourinary cancers in China / 中华男科学杂志

Increasingly accumulated results from randomized controlled trials and other clinical studies have demonstrated that male circumcision reduces the risks of acquisition and transmission of HIV, HPV, HSV-2, and other sexually transmitted infections, and thus has a potential role in preventing cervical cancer, penile cancer and prostate cancer. The prevalence of male circumcision in China is currently less than 5%. The clinical evaluation studies and randomized controlled trials of the Shang Ring device showed excellent safety profiles, extremely high acceptability, and satisfaction among the participants and service providers in Africa and China. Given the recent recommendations by the World Health Organization and the Joint United Nations Program on HIV/AIDS (UNAIDS), voluntary medical male circumcision should be promoted in China at the national level as an important alternative intervention to reduce reproductive tract infections and prevent both males and females from reproductive tract cancers. More emphasis is required on the studies of the long-term health benefits of male circumcision in uro-andrology.

Clinical studies of shang ring male circumcision in China and Africa / 中华男科学杂志

HIV/STIs remain a major global public health problem. One of the global strategies for the prevention and control of HIV/STIs is to interrupt their transmission, which requires the public health methods based on scientific evidence and cost-effectiveness. The scale-up of male circumcision services in the priority countries of the HIV-prevention project in sub-Saharan Africa has been hampered by the scarcity of trained providers and relative technical difficulty of male circumcision techniques recommended by WHO and UNAIDS. Shang Ring is an innovative and disposable device for male circumcision, which has been safely used for over 600 000 males in China since 2006. Clinical studies of more than 3 000 cases of Shang Ring circumcision in China, Kenya, Zambia, and Uganda have demonstrated its safety, effectiveness, acceptability and ease of use. The most obvious advantages of Shang Ring include short procedure time (3-6 min), excellent postoperative cosmesis, low rate of complications, high acceptance by clients and providers, ease of use, and standardization for reliable performance. As an innovative technique, Shang Ring has a great potential for facilitating the safe and effective scale-up of circumcision services. This article comprehensively reviews the clinical studies of Shang Ring male circumcision in China and Africa.

The making of a good male infertility microsurgeon: learning experience at Weill Cornell Medical College of Cornell University / 中华男科学杂志

Male infertility microsurgery represents the fastest growing sub-specialty in urology and clinical andrology over the past two decades. The importance of microsurgery for male infertility has risen as a part of the urologist's armamentarium in the medical and surgical management of male infertility. Despite the advances in male infertility microsurgery in China, the lack of standardized and well-organized training programs for male infertility microsurgery remains a serious problem affecting its development. In this article, Zhao and Peng have shared their experience with the learning curve of male infertility microsurgery at the Center for Male Reproductive Medicine and Microsurgery, Weill Medical College of Cornell University, which centers on how to pay attention to the details and basic principles of microsurgery. Male infertility microsurgery is physically, technically and mentally challenging, and must be first learned in the laboratory. Clinical success depends heavily upon appropriate training in a microsurgical laboratory. Good training can significantly reduce operation time and surgical errors as well as improve the quality of outcomes.

Progress in the clinical studies of male circumcision using the Shang Ring / 中华男科学杂志

Male circumcision can reduce men's risk of HIV infection from heterosexual intercourse by 60% and is therefore recommended as an important strategy for HIV prevention in Africa by WHO and UNAIDS. However, rapid expansion of male circumcision efforts could be greatly facilitated by a safer, more effective and acceptable male circumcision surgical technique or device. Shang Ring is a simple technique developed in China. It allows a circumcision to be completed with minimal bleeding, without suturing, and in only 3-5 min and reported complications are few. A standardized adult male circumcision surgical protocol utilizing the Shang Ring device was developed in 2008 in China. Several surgical training courses using this protocol were successfully held in 2009 and 2010 in China. A recent pilot clinical study of the Shang Ring was conducted to evaluate its safety and efficiency in Kenya in 2009. The results and acceptability among study participants were excellent and confirmed many of the advantages seen in the earlier Chinese studies from Wuhu, Ningbo and Xi'an, suggesting that the Shang Ring is safe for further studies in Africa, thus, could facilitate more rapid roll-out of adult male circumcision through task shifting, surgical efficiencies and better acceptability. Further international investigations of the Shang Ring technique have now been planned for Kenya and Zambia in 2011. Moreover, adult male circumcision utilizing the Shang Ring device is now being considered as ope of the potential candidate techniques to be used in the scale-up of adult male circumcision services for HIV prevention in WHO priority countries in Africa. This review article summarizes Shang Ring related clinical studies, seminars and surgical workshops, publications and presentations conducted between February 2008 and December 2010 in China, the United States and Africa.

Microsurgical approaches to the treatment of obstructive azoospermia / 中华男科学杂志

In the past 5 to 10 years, very few fields in modern medicine have changed so dramatically as reproductive medicine, especially for the treatment of male infertility. Advances have been made in intracytoplasmic sperm injection (ICSI), refined microsurgical reconstructive techniques (vasovasostomy and vasoepididymostomy), and microsurgical techniques of surgical sperm retrieval from the epididymis and testis. All men with epididymal obstruction (obstructive azoospermia) now have the opportunity to father their own biological children. In this article, the authors reviewed the most updated microsurgical vasovasostomy, vasoepididymostomy techniques and surgical indications as well as the key factors for successful microsurgical treatment. They also predicted the future directions and discussed the advantages of microsurgical techniques, emphasized the significant roles of microsurgical training for urological doctors to treat male infertility.
