Abstract:

<strong>Background:</strong> An essential and significant first step in evaluating testicular function is testing testicular size and characteristics of the semen. The most significant radiological method for accurately measuring testicular volume is considered to be ultrasound. Numerous reproductive endocrine factors affect testicular size. Measurements of testicular size and volume are related to the assessment of male fertility. The seminiferous tubules comprise between 70% and 80% of the bulk of the testicular mass. It is believed that testicular size serves as a gauge for spermatogen

Abstract Purpose Ultrasonography is a useful tool to measure testicular volume. According to the European Society of Urogenital Radiology, the combination of testicular atrophy and testicular microlithiasis (TML) is a risk factor for testicular cancer.

Abstract:

Background: Infertility is a major cause of marital disharmony in Nigeria because of the high premium placed on childbearing. Unfortunately, the blame is on the woman most times in Nigeria. Seminiferous tubules comprise 80-90% of testicular mass. Thus, the testicular volume is an index of spermatogenesis. Therefore, accurate testicular volume will help in assessing testicular function if there is no obstruction.

Abstract:

Cryptorchidism, affecting 1–4% of full-term male infants, poses long-term risks of infertility, hormonal dysfunction, and testicular malignancy if untreated. Orchiopexy, the gold-standard surgical intervention, aims to reposition the testes into the scrotum to preserve fertility and hormonal function. However, postoperative testicular atrophy, characterized by a ≥20% reduction in testicular volume, can undermine these benefits, necessitating adjuvant therapies to salvage compromised gonadal tissue.

Abstract:

Pediatric varicocele has an overall prevalence of 15%, being more frequent as puberty begins. It can damage testicular function, interfering with Sertoli cell proliferation and hormone secretion, testicular growth and spermatogenesis. Proper management has a pivotal role for future fertility preservation. The aim of this review was to discuss the diagnosis, management and treatment of childhood and adolescent varicocele from an endocrinologic perspective, illustrating the current evidence of the European Society of Pediatric Urology (ESPU), the European Association of Urology (EAU), the Americ

Abstract:

ABSTRACT: Testicular blood flow increases bilaterally in animals with experimental left varicocele (ELV). The present experiments were undertaken to determine if increases in testicular intravascular volume and capillary growth were potential contributors to this increase in flow. Testicular intravascular volume (μl/g) was estimated by determining testicular vascular 125I‐albumin space. Microvessel mitotic activity was estimated by examining 3 H‐thymidine incorporation into endothelial nuclei, as assayed by silver grain localization over microvessel endothelial nuclei after exposure of testes

Abstract:

The male transitional phase is of fundamental importance for future fertility. This aspect is largely neglected in clinical practice. This opinion aims to shed light on these issues. The children frequently complete the transition phase with a slight reduction of testicular volume. The system of detecting testicular volume is often inadequate. These patients evidently complete puberty in an incomplete way because they do not reach an adequate testicular volume, albeit in the presence of adequate height and regular secondary sexual characteristics.

ABSTRACT: Gonadotropin‐releasing hormone (GnRH) agonists regulate testicular interstitial fluid (tIF) volume, most probably via specific receptors on Leydig cells. The aim of this study was to confirm the interaction between GnRH and Leydig cells in regulation of testicular fluid, and to examine the effects on serum proteins in testis. Unilateral intratesticular injection of a GnRH agonist (100 ng/testis) caused a 50% reduction in tIF volume within 2 hours. Destruction of Leydig cells by treatment with ethane dimethane sulfonate also caused a similar decline in tIF volume; however, GnRH agonis
