INTRODUCTION To study the impact on adult's fertility of serum inhibin B levels in adolescent patients with idiopathic varicocele after minimally invasive surgical correction and to compare fluctuation of pituitary-testis hormonal values and testicular volumes. MATERIALS AND METHODS A case-control study was carried out on a group adolescent patients (n=60) affected by idiopathic left varicoce...

This study is the first to investigate the role of the KATP channel in the possible protection mediated by nicorandil against cyclophosphamide-induced lung and testicular toxicity in rats. Animals received cyclophosphamide (150 mg/kg/day, i.p.) for 2 consecutive days and then were untreated for the following 5 days. Nicorandil (3 mg/kg/day, p.o.) was administered starting from the day of cyclop...

The objectives of this study were to evaluate the potential use of color Doppler ultrasound to characterize blood flow to the stallion testis, and to establish reference values for Doppler measures of blood flow in the testicular artery of the stallion. Both testes from each of 52 horses were examined using a pulsed-wave color Doppler ultrasound with a sector array 5/7.5 MHz transducer with a 1...

AIM To perform quality control studies on testicular volume measurements for a multi-center epidemiological study of male reproductive function. METHODS We constructed a data matrix with a balanced assignment for 2 consecutive days by ten investigators (andrological career: 4-21 years) from five institutions and 12 male volunteers aged 20-26 years. Testicular volume was measured by Prader's o...

Background: Obesity in men, particularly when central, is associated with lower total testosterone [TT], free testosterone [FT] and sex hormone-binding globulin [SHBG], and a greater decline in TT and FT with increasing age compared with lean men. Obesity-related conditions such as obstructive sleep apnea, insulin resistance and type 2 diabetes mellitus are independently associated with decreas...

Background: Varicocele (VCL) impacts the testicular tissue partly by down-regulating the antioxidant status accomplished with reducing the intra-testicular endocrine potential. It has been reported that the HSP70 families play a critical role in spermiogenesis. Therefore, current study was aimed to evaluate the protective effect of exogenous testosterone and vitamin E administration on VCL-indu...

BACKGROUND Measurement of testicular artery blood flow is used in several species to evaluate reproductive function and testicular and scrotal pathology. In dogs there are inconsistent reports about normal flow in post-pubertal dogs and no information concerning pre-pubertal dogs. The aim of this study was to describe regional differences in testicular artery blood flow in clinically normal pos...

background the gonadectomy in patients with androgen insensitivity syndrome (ais) has been conventionally performed using laparotomic techniques. but currently several reports have suggested laparoscopic gonadectomy in these patients because of shorter hospital stay and minimal postoperative pain and hemorrhage. objective to report the laparoscopic gonadectomy in 11 patients suffering from andr...

PURPOSE To evaluate the relationship between unilateral or bilateral criptorchidism, patient age, primary location of the gonad and modality of treatment with testicular volume and hormonal status at 18 years in patients diagnosed and treated for cryptorchidism during childhood. MATERIALS AND METHODS Testicular volume, LH, FSH, and testosterone were evaluated in 143 young men at 18 years trea...
