Sertoli cell only syndrome induced by a varicocele

Abstract

A case is reported which describes the severity of testicular histological damage that can be induced by a high-grade varicocele in a male with secondary infertility. A chart review of a patient’s case was performed. A 34-year-old male with a three-and-a-half-year-old son who was conceived spontaneously with timed intercourse, with a grade three left varicocele, who’s semen parameters progressed to non-obstructive azoospermia (NOA). He did not regain sperm in the ejaculate three or six months post left subinguinal microsurgical varicocele repair. He underwent bilateral microdissection testicular sperm extraction (microTESE) without identification of sperm in the testicular samples. A testicular biopsy from the time of microTESE revealed a Sertoli cell only pattern. A high-grade varicocele has the potential to induce sufficient testicular damage to result in the most severe testicular histological architecture associated with nonobstructive azoospermia (NOA), Sertoli cell only syndrome (SCOS).
