Despite a long history and seeming simplicity, testicular prosthesis is associated with a lot of unresolved issues. As new publications appear, the sharpness of the discussion around issues related to prosthetics does not tend to decrease.
The review is based on publications on testicular prosthesis in adolescence and adulthood published in PubMed databases (https://www.ncbi.nlm.nih.gov/pubmed/) and Scientific Electronic Library Elibrary.ru (https://elibrary.ru/) was done. Only articles published in peer-reviewed journals were selected. The search was carried out using the following keywords: "testicular prosthesis", "structure of patients", "social rehabilitation", "social adaptation", "complications", "repeated implantation of testicular prosthesis". A total of 146 sources have been identified (predominantly over the past 10 years), and 44 have the highest scientific value and have been selected for citation and analysis.
Testicular prosthesis is an important component of the psychological and physical well-being of the patient after orchiectomy, normalization of reproductive function and sexual adaptation [1, 2]. A body defect that occurs after an orchiectomy is in most cases perceived as a psychologic trauma.
The evaluation of the results by both specialists and patients certainly deserves serious attention, but the works dedicated to this issue in detail are sparse, contradictory and do not fully disclose the problem.
Many issues related to testicular prosthesis remain open for discussion. There is a trend in clarification of the optimal age of the intervention, surgical technique and complications. The evaluation of the results from both a professional point of view and the patient's perception and satisfaction is currently far from being resolved, therefore, such studies are still relevant.
