TESTICULAR REGRESSION SYNDROME: PRACTICE VARIATION IN DIAGNOSIS AND MANAGEMENT.

Abstract

Abstract Objective: The purpose of this study was to assess clinical practice patterns with regard to diagnosis and management of testicular regression syndrome (TRS), a condition in 46,XY males with male-phenotypic genitalia and bilateral absence of testes. Methods: A retrospective review was conducted at two large pediatric academic centers to examine diagnostic and management approaches for TRS. Results: Records of 57 patients were reviewed. Diagnostic methods varied widely between patients and included hormonal testing, karyotype, imaging, and surgical exploration, with multiple diagnostic methods frequently used in each patient. Of the 30 subjects that had reached adolescence at the time of the study, 17 (57%) had gaps in care of more than five years during childhood. Thirty subjects had received testosterone replacement therapy at a mean age of 12.1±1.0 years. 47% had a documented discussion of infertility. 82% discussed prosthesis placement with 35% having prostheses placed. 23% were seen by a psychosocial provider. The between-site differences were age at fertility discussion, age at and number of prostheses placed, and type/age of testosterone initiation. Conclusion: Our findings highlight the wide variation in diagnostic approaches, follow-up frequency, testosterone initiation, fertility counseling and psychosocial support for patients with TRS. Developing evidence-based guidelines for the evaluation and management of TRS would help reduce inconsistencies in care and unnecessary testing. Ongoing follow-up and coordination of care, even during the years when no hormonal treatment is being administered, could lead to opportunities for psychosocial support and improved interdisciplinary approach to care.
