“…SNTs are typically not as large as the two normal testes, making polyorchidism more likely to go undetected for a long time. There are four types of polyorchidism (Table 1 and Table 2; Haddock and Burns, 1987;Bergholz 2007;Friedman, 2015). The most common clinical presentation of triorchidism (i.e., presence of a single extra testicle) is painless swelling (Abduljabbar, 2015;Gune and Gune, 2021).…”

“…In contrast, the right SNT was supplied by the inferior right epigastric artery but was atrophied and surrounded by adipose tissue.The above results suggest some factor(s) affecting "duplicity" and "migration" of the developing gonads.A survey of the literature focused on polyorchidism shows little to no mention of genetic factors that may play a role in the development of this condition. It has been hypothesized that polyorchidism is caused by the division of the genital ridge during embryological development(Lawrentschuk and MacGregor, 2004;Friedman, 2015;Satoh, 1991). Based on this theory, it can be suggested that in individuals with polyorchidism there may be a genetic factor that has led to the increased likelihood that anomalous division may occur.…”

Polyorchidism is a rare congenital disorder defined as the presence of more than two testicles for which the underlying etiology is unknown. This report examines a novel case, correlates findings to the literature, and discusses potential mechanisms of dysgenesis. This study was conducted on a 96-year-old male cadaver. Meticulous skilled dissection was done with careful attention to the pelvis, the inguinal region, the scrotum and testes. Measurements of the scrotal testes (STs), supernumerary testes (SNTs), scrotal epididymides (SEs), supernumerary epididymides (SNEs), ductus deferens (DD) and supernumerary ductus deferens (SDD) were taken, and testicular volume was calculated. Sagittal sectioning of STs, SNTs, SEs and SNEs was performed and, using standard histologic protocol, tissues were processed, stained with H&E, and examined. Histological findings supported the anatomical suspicion of high, bilateral inguinal polyorchdism, or tetraorchdism, in this patient. STs and SNTs have normal, gross morphological features. The left SNT was supplied by the testicular artery, and the right SNT by the inferior epigastric artery. Both SNTs and SNEs were infiltrated with adipose tissue, whereas the scrotal homologues were histologically normal. Testicular volumes were 26.5 cm3 and 23.7 cm3, and 12.3 cm3 and 0.55 cm3, for the left and right STs and SNTs, respectively. The left and right SEs measured 7.2 cm and 7.0 cm; the left and right SNEs measured 4.7 cm and 1.7 cm, respectively. The left DD measured 40.2 cm from the scrotum. The SDD from the left SNT measured 5.9 cm and joined the main ductus 16 cm proximal to its origin. The right main DD measured 39.2 cm, and the SDD from the right SNT was 3.2 cm and joined the main DD 17.4 cm proximal to its origin. The current work suggests a novel classification for polyorchidism of Type 3, Subgroup B, or SNT attached to the draining epididymis and vas deferens without reproductive potential and SNT located outside the scrotal sac. Clinicians must correlate anatomical and histological findings in suspected polyorchids to avoid misdiagnosis of SNTs as benign lipomas.
