The study evaluated the role of imaging studies in the diagnosis of impalpable undescended testes. A total of 40 children referred with 45 impalpable undescended testes had an ultrasound scan and clinical examination by a pediatric surgeon. 22 out of these 45 testes were found to be palpable on clinical examination by a pediatric surgeon. Of the remaining 23 boys (23 units of testes), 21 underw...

Hormone-sensitive lipase-knockout (HSL-/-) mice exhibit azoospermia for unclear reasons. To explore the basis of sterility, we performed the following three experiments. First, HSL protein distribution in the testis was determined. Next, transcriptome analyses were performed on the testes of three experimental groups. Finally, the fatty acid and cholesterol levels in the testes with three diffe...

BACKGROUND Testes size is used as a proxy of male intrasexual competition, with larger testes indicative of greater competition. It has been shown that in some taxa, social mating systems reflect variance in testes size, but results are not consistent, and instead it has been suggested that genetic patterns of mating may reflect testes size. However, there are different measures of genetic patt...

ischemia-reperfusion injury is a possible cause of testicular damage and infertility after testicular torsion and detorsion. the purpose of this study was to evaluate the effect of ghrelin on testicular ischemia-reperfusion damage. a total of 30 adult male rats were selected for the study and divided randomly into 3 groups, each containing 10 rats. animals in the testicular torsion and ghrelin ...

the aim of the present study was stereological evaluation of testes of azoospermic animal model using busulfan in rat. three groups of male adult rats were used in this study. the first group was injected by single dose of busulfan (10 mg kg-1) and their testes were removed on day 35 post injection. the second group received double doses of busulfan with 21 days interval and their testes were r...

diazinon is an organophosphate which exerts tissue damages by generating free radicals thereby inducing oxidative stress. the purpose of this study is to determine the protective effect of salvia officinalis l.extract on testes of rats intoxicated by diazinon. in this experimental study, 45 mature male rats were equally divided into three groups of control (c), diazinon (dzn) and diazinon-extra...

INTRODUCTION Undescended testes are recognised in 1% to 2% of boys during the first year of life, and about 20% of them are impalpable. Ultrasonography (US) may establish the localisation of the testis but the final diagnosis is usually determined laparoscopically. AIM To evaluate long-term results of laparoscopic treatment of boys with impalpable testes and sensitivity of preoperative ultras...

BACKGROUND The aim of the present study is to make a comparative study in human fetuses and in patients with cryptorchidism, analyzing the incidence of a number anomalies of the testes for both populations. METHODS We studied 326 testes from 163 human fetuses ranging in age from 10 to 35 weeks postconception (WPC) and 133 testes from 101 cryptorchid patients aged from 1 to 15 years old (mean,...

BACKGROUND Very few studies are available that describe the role of laparoscopy in adults with impalpable testes. This study compares laparoscopy with ultrasonography in this subset of patients. METHODS Fourteen adults, having a mean age of 21 years, with 19 undescended testes were evaluated. None of the testes was palpable, preoperative ultrasound localized 7 testes (36.8%), but a change in ...

The aim of this study was to evaluate the testicular volume and structure using ultrasound (US) before and up to 3 years after orchidopexy in children with different age.A total of 128 patients underwent orchidopexy for undescended testes. Afterwards, patients were invited for annual follow-up and control scrotal US. The total number of analyzed testes after orchidopexy was 184. Patients were d...
