Multiple variations of the right renal and testicular vessels were found during routine dissection in a 65-year-old male cadaver. The cadaver was healthy and did not have any other anomalies. The variations found were: presence of three right renal arteries, origin of the right inferior suprarenal artery from the middle right renal artery, two right renal veins, origin of the right testicular a...

Testicular function is particularly susceptible to vascular insult, resulting in a negative impact on sperm production and quality of the ejaculate. A prompt diagnosis of testicular dysfunction enables implementation of appropriate treatment, hence improving fertility forecasts for stallions. The present research aims to: (1) assess if Doppler ultrasonography is a good tool to diagnose stallion...

OBJECTIVE To assess the effects of two methods of freezing on testicular sperm DNA from subjects with obstructive azoospermia and to compare these with samples of fresh and freeze-thawed testicular sperm from fertile men. DESIGN The Comet assay was used to determine the percentage of undamaged DNA in fresh testicular sperm, testicular sperm freeze-thawed in suspension and in a biopsy sample (...

BACKGROUND Most patients with testicular cancer are infertile; thus, the preservation of the sperm after surgery is an important factor to consider. We report two cases of bilateral testicular cancer in patients who underwent bilateral higher orchiectomy and simultaneous testicular sperm extraction. CASE PRESENTATION Two Asian-Japanese men were referred to our hospital with bilateral testicul...

The interstitial tissue of the opossum testis includes interstitial or Leydig cells, macrophages, and small cells which morphologically resemble mesenchymal cells. The latter are thought to give rise to mature interstitial cells. The most prominent feature of the interstitial cell cytoplasm is an exceedingly abundant agranular endoplasmic reticulum. This reticulum is generally in the form of a ...

In guinea pig testes perfused with either glutaraldehyde or osmium tetroxide fixative, the cytoplasm of the interstitial cells contains an exceptionally abundant agranular endoplasmic reticulum. The reticulum in central regions of the cell is a network of interconnected tubules, but in extensive peripheral areas the reticulum is commonly organized into closely packed, flattened cisternae which ...

We report a case of intra-abdominal testicular tumor in a 36-year-old married lady presenting with chief complaints of primary amenorrhea. The patient was later diagnosed with testicular feminization syndrome, a form of male pseudohermaphroditism. This testicular tumor was histologically proven as seminoma. Due to rarity, imaging findings in patients with testicular feminization syndrome and in...

Testicular carcinoid generally presents either with a palpable (painful or painless) or rarely a nonpalpable mass (when it is diagnosed incidentally on scrotal imaging) of the involved testis. An ipsilateral testicular carcinoid presenting exclusively with contralateral testicular symptoms has never been described in the literature to date. We report a case of nonpalpable left testicular carcin...

OBJECTIVES To review our 10-year experience with uncommon testicular tumours in children (prepubertal testicular and paratesticular), to review previous reports, and to determine the appropriate management of these rare tumours, specifically the role of testicular-sparing surgery. PATIENTS AND METHODS We retrospectively reviewed all cases of testicular tumours managed at our institution betwe...

Objectives To compare elastography measurements in men with normal testicular tissue, testicular microlithiasis and testicular cancer. Methods A total of 248 consecutive patients were included. All men provided written informed consent. Testicular stiffness was assessed using shear wave elastography (SWE). Three SWE velocity measurements were assessed in each testicle. The patients were divid...
