CONTEXT AND OBJECTIVE Testicular torsion is a medical and urological emergency because it can lead to loss of the organ. The theory of seasonal testicular torsion occurrence is based on studies from institutions located in cold and temperate regions. The objective here was to determine whether cold weather is associated with higher incidence of testicular torsion in a tropical country, such as ...

UNLABELLED Testicular lymphoma was first reported by Malassez and Curling in 1866. Primary testicular lymphoma constitutes only 1 - 7% of all testicular neoplasms and less than 1% of all non Hodgkin lymphoma. The authors report a new case of primary testicular lymphoma and highlight its diagnostic and therapeutic challenge. We report the case of a 26-year old man without a particular past medic...

As an endocrine disease, type 2 diabetes mellitus (T2DM) can cause testicular damage which induces male infertility. However, the underlying mechanism is still not clear. We prove that T2DM induced testicular microcirculation impairment involves the decrease of VEGF and these actions are regulated by PI3K/Akt pathway. In our study, rats were divided into three groups (n=8): control group, diabe...

This study was carried out to evaluate testicular ultrasound as a breeding soundness examination (BSE) and biometric tool for West African dwarf (WAD) buck goats. Twelve bucks of proven breeding capability were selected for this purpose. Scrotal circumferences of these animals were measured using a flexible tape. Testicular ultrasound was carried out on the transverse and longitudinal planes on...

Healthy specimens of Colisa fasciatus exposed to sub lethal concentration of hexavalent chromium (4.8 mg/L) for 15 days revealed no significant alterations in any testicular architecture during its different phases. However, 30 days exposure revealed distarded shape of lobule and lobular wall, scattered interstitial leydig cells during preparatory phase of testicular cycle where as during spawn...

Cryptorchidism is the most well-defined risk factor for the development of testicular GCT; if uncorrected, the relative risk is 5 to 9 times that of healthy age-matched controls.[1] Approximately 10% of all cases of testicular GCT are associated with cryptorchidism and 10% of patients with cryptorchidism develop testicular GCT.[2,3] When testicular GCT develops in patients with unilateral crypt...

To identify the predictive factors for testicular sperm extraction (TESE) and to understand the pathology associated with TESE, we carried out a prospective study in 40 consecutive men with azoospermia due to primary gonadal failure. The main outcome measure was the retrieval of at least one testicular spermatozoon. Endocrine and biophysical profiles, testicular histology, Johnsen score and tes...

Testicular torsion is one of the few emergencies in pediatric urology which requires an accurate and timely diagnosis in order to avoid testis loss. It is not an uncommon event affecting a young male population. In fact, testicular torsion is more common than testicular tumors for this same age group, yet testicular torsion has not been given the public attention it deserves as a male health ri...

OBJECTIVE Primary extragonadal germ cell tumors are rare and their histogenetic origin is not clear. We describe two cases presenting as primary retroperitoneal germ cell tumors without clinical evidence of testicular tumor. METHODS A 21 and 18 years-old patients presented retroperitoneal choriocarcinoma and yolk sac tumor, respectively. In both cases, testicular palpation was not suspicious ...

Segmental testicular infarction is a rare cause of acute scrotum. Its aetiology is not well defined and it can be clinically confused with a testicular tumour. Because the differential diagnosis between segmental testicular infarction and testicular tumour can be difficult, most authors in the past recommended surgery. Imaging plays an important role in the preoperative diagnosis, with a colour...
