OBJECTIVE The incidence of varicocele is approximately 15% in adolecent men. Early treatment with varicocele is aimed to resolve testicular hypotrophy and ensure catch-up growth. The aim of this study was to evaluate ipsilateral catch-up growth rates relative to contralateral testicular growth in adolescents with varicocele undergoing microsurgical subinguinal varicocelectomy. MATERIAL AND ME...

BACKGROUND In view of the high cure rates in patients with testicular germ cell tumors (TGCT), increasing clinical importance is attached to protection of fertility. Long-term infertility due to cytostatic therapy may be expected in more than 50% of the patients at a cumulative dose of cisplatin > 0.6 g/m2. The standard procedure for fertility protection in cancer patients includes cryopreserva...

BACKGROUND To evaluate the improvement in semen quality and pregnancy rate after internal spermatic vein (ISV) embolization in men with nonobstructive azoospermia virtual azoospermia, or extremely severe oligoteratoasthenoazoospermia (OTA). METHODS A prospective cohort of 101 azoospermic or severe oligoteratoasthenospermic men of mean (+/-SD) age 34.1+/-7.7 years who underwent ISV between Sep...

The aim of the present study was to evaluate the effects of different seasons on the morphometric testicular parameters and the respective epididymal sperm parameters. Total numbers of 104 scrota of pubertal buffalo bull (24-48 months) include their contents were provided from the local slaughterhouse. Scrotal circumference was measured on its place before dissection. Morphological parameters o...

introduction: morphology and ultra-structure of myoid and sertoli cells were studied in patients with non-obstructive azoospermia who were admitted to testicular sperm extraction (tese) and intracytoplasmic sperm injection (icsi), by transmission electron microscopy (tem). materials and methods: 12 biopsies of testicular tissues from patients with non-obstructive azoospermia referred to royan i...

PURPOSE We assessed the long-term efficacy, complications and patient perceptions of microsurgical denervation of the spermatic cord in the treatment of chronic orchialgia. MATERIALS AND METHODS Microsurgical denervation of the spermatic cord was performed on 95 testicular units in 79 men (mean age 40.3 years, mean duration of pain 62 months, 16 bilateral) for chronic orchialgia. Conservative...

Background: Varicocele occurs in approximately 15% to 20% of the male population and it is the most common cause of poor semen parameters. It has been demonstrated that patients with varicocele have poor chromatin packing, DNA damage and nuclear anomalies than the healthy men. Therefore, the aim of this study was to evaluate sperm chromatin integrity and semen parameters in these patients after...

The introduction of the technique of intracytoplasmic sperm injection to achieve fertilization, especially using surgically retrieved testicular or epididymal sperm from men with obstructive or non-obstructive azoospermia, has revolutionized the field of assisted reproduction. The techniques for the retrieval of spermatozoa vary from relatively simple percutaneous sperm aspiration to open excis...
