ABSTRACT
In this study, two cases of triorchidism are reported. The first case (29 years) had two right discrete ovoid nontender, firm, mobile lumps with testicular sensation. The second case (32 years) had two left discrete ovoid nontender, firm, mobile lumps with normal testicular sensation. They were subjected to the estimation of serum follicle-stimulating hormone, luteinising hormone, free and total testosterone, alpha-fetoprotein, prostate-specific antigen, karyotyping and semen analysis. Imaging included ultrasonography, transrectal ultrasound, magnetic resonance imaging and intravenous pyelography. The first case had two testes in the right side. Each one had an epididymis where one vas deferens was palpated. The second case had two left testes with normal testicular sensation. The lower left lump represented normal-sized testis attached to its epididymis and a single palpated vas deferens. Diagnosis of the first case was triorchidism associated with left varicocele (grade I) with oligoasthenoteratozoospermic semen profile. Intracytoplasmic sperm injection was carried out resulting in a twin. Diagnosis of the second case was triorchidism with accessory testis on the left side associated with left varicocele (grade I) and asthenozoospermic semen profile that was submitted to medical treatment. It is concluded that triorchidism is an uncommon congenital anomaly that should be not overlooked in diagnosing scrotal masses.
