OBJECTIVE: To describe a case of supernumerary minute ring chromosome (SMRC) in an infertile man, with the concurrent finding of a left varicocele. DESIGN: Case report. SETTING: Urologic infertility clinic in a university hospital. PATIENT(S): Male patient presenting with primary infertility. INTERVENTION(S): Karyotyping, genetic counseling, and microsurgical left varicocelectomy. MAIN OUTCOME MEASURE(S): Sperm concentration and motility, chromosomal number and structure. RESULT(S): Fluorescence in situ hybridization revealing SMRC 14. Sperm concentration and motility improved after left varicocele repair. CONCLUSION(S): A karyotype should be included in the evaluation of severe oligospermia. Although SMRC 14 may be associated with fertility problems, repair of a coexisting varicocele should be considered in these patients.
