INTRODUCTION Failure to perform surgical repair of varicocele before puberty is among the common causes of male infertility. The purpose of this study was to evaluate the testicular volume and fertility potential in men after laparoscopic varicocelectomy conducted in adolescence due to varicocele and concomitant testicular hypotrophy. MATERIAL AND METHODS From 1996 through 2011, eighty-two ad...

OBJECTIVE To evaluate the ipsilateral catch-up growth rates compared to contralateral testicular growth in adolescents with varicocele undergoing microsurgical inguinal varicocelectomy. MATERIALS AND METHODS Between December 2005 and May 2007, 39 adolescent patients with grade 2-3 varicocele admitted to our clinic with complaints of pain and/or testicular asymmetry were operated. Preoperative...

At the onset of puberty, seminiferous tubules rapidly increase in diameter, thereby occupying a greater proportion of the testis, resulting in a rapid increase in testicular size. The objective of the current studies was to evaluate ultrasonography for assessing testicular diameter, as a basis for ranking boars relative to their extent of pubertal development. In the initial study, prior to cas...

BACKGROUND In patients with hereditary or constitutional chromosomal anomalies, testicular carcinoma can develop sporadically or on the basis of an underlying hereditary genetic defect. Greater knowledge of these genetic defects would provide more insight into the molecular pathways that lead to testicular carcinoma. To the authors' knowledge, little attention has been paid to date to the comor...

The objectives of this study were to investigate patients treated for scrotal trauma at our institute for the last three decades to describe our experience with an emphasis on the etiologies and ultrasonographic findings in these patients. We reviewed medical records of patients who underwent scrotal ultrasonography for evaluation of testicular trauma at our institutes from 1986 to 2015. Trends...

OBJECTIVE After review of the pediatric literature, we report on the prevalence of testicular microlithiasis and its relation with benign and malign entities. We provide a guideline for the management of boys with testicular microlithiasis. MATERIALS AND METHODS The databases searched were Medline, Web of Science, Embase and the Cochrane Library. Data on the rates of testicular microlithiasis...

In the present study, variation...

OBJECTIVE To investigate the effectiveness of intracytoplasmic sperm injection (ICSI) using testicular sperm as a strategy to overcome infertility in men with high sperm DNA fragmentation (SDF). DESIGN Prospective, observational, cohort study. SETTING Private IVF centers. PATIENT(S) A total of 147 couples undergoing IVF-ICSI and day 3 fresh ETs whose male partner has oligozoospermia and h...

OBJECTIVES Analyze the anatomic variations of the testicular veins in human cadavers and fetuses. MATERIALS AND METHODS One hundred male adult cadavers and 24 fetuses were studied. Four anatomic aspects were considered: 1) Number of testicular veins, 2) The local of vein termination, 3) Type and number of collaterals present and 4) Testicular vein termination angle. RESULTS Cadavers - Right...

Testicular Leydig cells contain abundant cytoplasmic lipid droplets (LDs) as a cholesteryl-ester store for releasing cholesterols as the precursor substrate for testosterone biosynthesis. Here, we identified the protein composition of testicular LDs purified from adult mice by using mass spectrometry and immunodetection. Among 337 proteins identified, 144 were previously detected in LD proteome...
