Objective: To discuss the classification systems and pose a rationale for a flexible approach. We also propose our surgical approach for vasoepididymal or epidymo-epididymal approximation. Polyorchidism is a rare congenital anomaly with about 200 cases reported.
Methods: We present 8 cases of polyorchidism treated at our institute from 1992 to 2010. To our knowledge, this is the most numerous single-center experience. We performed vasoepididymal or epidymo-epididymal approximation to restore near-normal anatomy plus stabilization of the testicular and ductal system to facilitate possible future reconstructive surgery.
Results: In the case of contralateral anorchia or an atrophic testis, a supernumerary testis can fairly replace the contralateral counterpart. The reproductive potential of the supernumerary testis must not be ignored. Also, the malignant potential of the supernumerary testis should not be overestimated.
Conclusion: A careful pursuit of the vessel and vasal route during surgery for an undescended testis, judicious use of laparoscopy, and a lower threshold for diagnosis both on imaging studies and during surgery might result in a greater number of cases of polyorchidism in the daily practice of pediatric urology.

Introduction: Triorchidism is a rare anomaly whose management raised considerable discussion. Several factors must be considered, including the patient's age, the testes location, their functional status, and the accessibility and compliance for follow-up. We present a case of triorchidism diagnosed incidentally during a routine hernioplasty procedure, serving educational and informative purposes.

: Persistent Müllerian duct syndrome (PMDS) is a rare disorder of sex development (DSD) caused by mutations in the genes coding anti-Müllerian hormone (AMH) or the AMH receptor, characterized by the persistence of Müllerian derivatives, the uterus and/or fallopian tubes, in otherwise normally virilized boys. Testicular regression syndrome is common in PMDS, yet the association with supernumerary testis has been reported in only two patients where genetic testing was not performed. : Thus, we report an individual with this particular association caused by a previously unreported homozygous variant in the gene to enable future genotype-phenotype correlations in this rare disorder.

Introduction And Importance: Poly-orchidism is a rare congenital anomaly of the genitourinary system, which is characterized by the presence of more than two testicles, also being termed as "supernumerary testis". Tri-orchidism is the most frequently encountered form of poly-orchidism, which is defined as the presence of more than two intra- or extra-scrotal testicles.
Case Presentation: The authors present a case of a 16-year-old male who presented with a complaint of an empty left scrotal sac, and was later diagnosed as a case of tri-orchidism with each testis in bilateral hemipelvis confirmed by ultrasound with Doppler and MRI.

Background: Polyorchidism, defined by the presence of more than two testes, is a rare congenital condition with an unclear etiology. It is hypothesized that the abnormal division of the genital ridge in the fetal embryonic period is responsible for the development of one or more supernumerary testicles. Due to the rarity of polyorchidism and its wide range of clinical presentations, the management of polyorchidism is unclear.

Duplicate testes lined in series were observed in the right scrotum of a 6-week-old Sprague-Dawley rat in a single-dose toxicity study. Of the two right testicles, one was spherical and less than half the size of a normal testis. The other was oval-shaped, slightly smaller than a normal testis, and possessed clear, tortuous blood vessels similar to those of a normal testis.
