BACKGROUND About 3-5% of all patients with testicular germ cell tumour (GCT) develop a contralateral cancer, the majority of which arise within 10-15 years. Little is known about the risk of second GCTs after more than two decades. Here we present 3 cases with very late presenting contralateral GCT and provide a summary of similar cases reported previously. CASE PRESENTATIONS (1) This white C...
OBJECTIVES To determine the accuracy of orchidometry and ultrasonography for measuring the testicular volume by comparing the resultant measurements with the actual testicular volume in humans. METHODS The testicular volume of 40 testes from 20 patients with prostate cancer (mean age +/- SD 74.5 +/- 7.5 years) was measured using the Prader orchidometer and ultrasonography before therapeutic b...
تومور دو طرفه بیضه همراه با هیپرپلازی مادرزادی آدرنال و کمبود آنزیم 11-هیدروکسیلاز از بیمارستان امام
The development of testicular masses in male patients with congenital adrenal hyperplasia due to 21 hydroxylase deficiency has been recognized for many years. We present here the eighth and ninth reported patient with bilateral testicular tumors associated with 11 hydroxylase deficiency. They were two brothers aged 7.5 and 5 yr. who had bilateral testicular tumors and diagnosed because of signs...
INTRODUCTION Vascular endothelial growth factor (VEGF) is known to influence testis function. Transforming growth factor alpha (TGF-α) is expressed in the postnatal testis, and has been demonstrated to stimulate testis development. Systemic diseases such as chronic renal failure (CRF) interfere with hypothalamic-pituitary-gonadal axis, which may cause defective steroidogenesis and gonadal funct...
Given the importance of reproduction field combined with use Pulsed-Wave (PW) ultrasound in clinical routine, this study aims to review application diagnostic method reproductive tract females and males canine species. A narrative was carried out by using scientific articles, monographs, dissertations thesis published available online databases: Periodical Capes (Coordination for Improvement Hi...
OBJECTIVE To investigate the relationship between testicular volume and semen parameter sin patients with unilateral high grade left varicocele. MATERIAL AND METHODS One hundred eighty seven patients who had left high grade varicocele aged 19-to-25 years were included in this study. All patients underwent a standard evaluation, including medical history and physical examination. The percentag...
PURPOSE Recent epidemiological studies have demonstrated an increasing incidence of testicular cancer in white men which appears to be correlated with the period of birth. Because this birth cohort phenomenon can explain etiological factors in testicular cancer, we determine whether this trend is present throughout the United States based on an analysis of testicular cancer incidence by birth c...
PURPOSE The hypothesis of association between testicular torsion and hyperactive cremasteric reflex, worsened by cold weather, has not been proved. Thirteen studies in the literature evaluated this issue, with inconclusive results. The aim of the present study was to evaluate the seasonality of testicular torsion in a large subset of patients surgically treated in Brazil, and additionally to es...
The objective of the present study was to analyse the influence of motility on the results of intracytoplasmic sperm injection (ICSI) when testicular spermatozoa are used for microinjection and to correlate this with testicular histology. A total of 197 ICSI treatment cycles (167 couples) was analysed retrospectively in which testicular spermatozoa were used, because of complete azoospermia, fo...
BACKGROUND Although testicular cancer is the most common cancer among 18- to 50-year-old males, healthcare providers seldom teach testicular self-examination techniques to clients, thus potentially missing opportunities for early detection. This form of cancer is easily diagnosable by testicular self-examination and is 96% curable if detected early. Periodic self-examination must be performed f...
