Objective: Testicular microlithiasis is a rare, usually asymptomatic, finding of the testes associated with various genetic anomalies and infertility. It is also widely believed that testicular microlithiasis is strongly associated with testicular tumor. The aim of this prospective study was to determine the true prevalence of testicular microlithiasis in an asymptomatic population by means of ultrasound screening.
Material And Methods: Healthy male volunteers (17-42 years old) were recruited from the annual Army Reserve Officer Training Corps training camp at Manisa, Turkey. A screening genitourinary history was obtained and a physical examination and screening scrotal ultrasound scan were performed.
Results: All men diagnosed with testicular microlithiasis underwent complete clinical evaluations, physical examinations and determination of tumor markers. Fifty-three men with testicular microlithiasis were identified from the 2179 ultrasound scans, giving a prevalence of testicular microlithiasis of 2.4% in this asymptomatic population. The age (mean+/-SD) of subjects with testicular microlithiasis was 23.9+/-4.2 years (range 20-31 years).
Conclusion: Our results suggest that there is no significant association between TM and testicular cancer, although it is difficult to rule out such an association without further studies with a longer follow-up period.

Background: Epididymal cysts (ECs) are uncommon in the pediatric population. The objective of this study was to evaluate the frequency, clinical characteristics, and management strategies of ECs in children.
Methods: We performed a retrospective review of pediatric scrotal ultrasounds between January 2014 and August 2022 to identify children with ECs.
A review of testicular histopathology in nonobstructive azoospermia.

One major challenge in male factor infertility is nonobstructive azoospermia (NOA), which is characterized by spermatozoa-deficient semen without physical duct blockage. This review offers a thorough overview of the histopathology of the testes in NOA cases, clarifying its complex etiology and emphasizing the possible value of histopathology inspection for both diagnosis and treatment. Variable histopathological findings have been linked to NOA, such as tubular hyalinization, Sertoli cell-only syndrome, hypospermatogenesis, and germ cell arrest.

Article Synopsis
- The Scrotal and Penile Imaging Working Group (SPIWG) of the European Society of Urogenital Radiology (ESUR) aimed to create guidelines for radiologists on assessing male infertility through scrotal imaging.
- Scrotal ultrasound (US) is highlighted as an important tool for identifying abnormalities that affect sperm parameters and other conditions related to male fertility.
- The recommendations include specific imaging techniques and evaluation criteria focusing on testicular volume, inhomogeneity, varicocele, and the presence of vas deferens or epididymal issues.
Testicular biopsies in men with testicular microlithiasis and additional risk factors for cancer: A case series.

Background: Testicular microlithiasis is the presence of small calcifications in the testicular parenchyma. The association between testicular microlithiasis and germ cell neoplasia in situ, a precursor to testicular cancer, is still unclear.
Objectives: To determine the incidence of germ cell neoplasia in situ in men with testicular microlithiasis and evaluate the indication for testicular biopsy according to risk factors in the form of male infertility/reduced semen quality, testicular atrophy, and history of cryptorchidism.
