Nov 3, 2020 · An acquired cause of small testes is testicular atrophy, which entails a testicular volume reduction of 20% compared with baseline volume or the normal contralateral testis [1,3]. Testicular atrophy may occur after infarction, inflammation, cryptorchidism, varicocele, or trauma . The presence of a heterogeneous testis in an older patient (>50 years old) in the absence of a testicular mass suggests tubular atrophy and sclerosis. These testes probably do not have to be sonographically followed up unless there is a strong risk factor, such as a previous testicular cancer or a known extratesticular malignancy (prostate, lung), which …Imaging results do not alter management recommendations per American Urological Association clinical guidelines. ... Testicular atrophy index on ultrasonography Laboratory tests Comments; 0% to 24%: Testicular atrophy is a medical condition in which one or both testicles (or "testes") diminish in size and may be accompanied by reduced testicular function. Testicular atrophy is not related to the temporary shrinkage of the surrounding scrotum, which might occur in response to cold temperature. The duration between the initial diagnosis of mumps orchitis and the ultrasonographic diagnosis of testicular atrophy after mumps orchitis ranged from 25 to 230 days (mean, 95.9 days). Results: Of the eight patients with testicular atrophy after mumps orchitis, the testes were affected unilaterally in seven patients (6 right-sided and 1 left ...Gender: Male. ultrasound. Markedly atrophic left testis with a heterogeneous echotexture. The hypothesis was that certain physical exam, imaging, and intra-operative findings could predict future testis atrophy and thus may be used to guide the clinician for or against orchiectomy after testicular detorsion.

However, the size of the testes decreases with age. From the mediastinum testis, several radiating septa extend into the testis forming 250-400 lobules. Each of these lobules contains 2-3 seminiferous tubules. An acquired cause of small testes is testicular atrophy, which entails a testicular volume reduction of 20% compared with baseline volume or the normal contralateral testis [1,3]. Testicular atrophy may occur after infarction, inflammation, cryptorchidism, varicocele, or trauma [2].

Of the 50 tumours in our series, 49 (98%) were malignant and 1 (2%) benign. SGCT represented approximately half of all malignant tumours (Table 1 ). An overactive muscle causes a testicle to become a retractile testicle. The cremaster muscle is a thin pouch-like muscle in which a testicle rests. When the cremaster muscle contracts, it pulls the testicle up toward the body. The cremaster reflex can be stimulated by rubbing a nerve on the inner thigh and by emotion, such as fear and laughter.Testicular torsion occurs when a testis torts on the spermatic cord resulting in the cutting off of blood supply. The most common symptom is acute testicular pain and the most common underlying cause, a bell-clapper deformity.

Testicular atrophy is the most commonly seen lesion in testicular toxicity. The least severe change in the germinal epithelium is the maturation arrest. This is characterized histologically by partial or complete loss of mature spermatids from the lumen of seminiferous tubules. As the degree of atrophy increases, there is ... Conclusion: Testicular asymmetry, with a smaller left testis, was seen in a considerable number of healthy adolescents. One out of five adolescents had a smaller left testis and met one of the threshold values currently used in varicocoele management.

While usually painless, varicoceles are clinically significant because they are the most commonly identified cause of abnormal semen analysis, low sperm count, decreased sperm motility, and abnormal …Ultrasound. At sonography, it appears as multiple small cystic or tubular anechoic structures that replace and enlarge the testicular mediastinum. The geographic shape, lack of mass effect, and lack of internal vascularity (Doppler flow) are helpful to distinguish this benign condition from a partially cystic tumour.The presence of a heterogeneous testis in an older patient (>50 years old) in the absence of a testicular mass suggests tubular atrophy and sclerosis.
