Testicular volume measured to be less than 12 mL is a sign of testicular atrophy. [10] In addition, testicular atrophy can be recognized as greater than 50% loss of testicular volume or a post-operative testicle with less than 25% of the volume of the opposite testicle. [ 23 ]
This can transiently or permanently disrupt natural testicular function by suppressing pituitary production of LH and FSH, potentially causing testicular atrophy (decreased testicular size ...
Embryonal cell carcinomas, a more aggressive tumor than seminoma usually occurs in men in their 30s. Although it is the second most common testicular tumor after seminoma, pure embryonal cell carcinoma is rare and constitutes only about 3 percent of the nonseminomatous germ cell tumors. Most of the cases occur in combination with other cell types.
Doppler ultrasound of the scrotum, in the axial plane, showing orchitis (as part of epididymo-orchitis) as hypoechogenic and slightly heterogenic left testicular tissue (right in image), with an increased blood flow. There is also swelling of peritesticular tissue. Blood – ESR high; Urine – Cultural & Sensitivity test; Ultrasound scanning

Hypogonadism means diminished functional activity of the gonads—the testicles or the ovaries—that may result in diminished production of sex hormones.Low androgen (e.g., testosterone) levels are referred to as hypoandrogenism and low estrogen (e.g., estradiol) as hypoestrogenism.
Sertoli cell-only syndrome (SCOS), also known as germ cell aplasia, is defined by azoospermia where the testicular seminiferous tubules are lined solely with sertoli cells. [2] Sertoli cells contribute to the formation of the blood-testis barrier and aid in sperm generation.
A testicular nubbin is the residual tissue of the human testis after a supposed perinatal vascular accident involving the testicular blood supply. The blood supply of the testis twists (called torsion) thereby cutting off the blood supply to the testis and results in testicular atrophy (shrinking).
