background: testis tissue xenografting and the resultant sperm in a xenograft may provide a unique approach to rescue the genetic material of males that die prematurely and is a model for the study of human spermatogenesis and can represent an alternative approach for fertility preservation in cancer patients. this study was aimed to evaluate the xenogenic dog sperm in formation of male pronucl...

Background: Formaldehyde is a chemical that used in fixed tissues and bodies. Formaldehyde during dissection of cadaver, evaporate and be released. Studies have shown that the gas increase endogenous opioids, nitric oxide and cytokines in plasma. These impacts can affect on gonadotropin hormones. The aim of this study was to investigate possible changes in gonadotropin and epithelial cells of t...

Prostate adenocarcinoma is the most common malignancy and the second leading cause of cancer related deaths in men. Testicular liposarcomas are uncommon soft tissue neoplasms. We report coexistence of prostate cancer and testicular liposarcoma in a 69 year-old-man because while orchiectomy endications are decreasing day by day, these second malignancies should not be missed.

Splenogonadal fusion is a rare congenital anomaly characterized by congenital fusion between the spleen and testicular tissue. In the literature, there are approximately 175 reported cases, and most of them are associated with cryptorchidism. In this article, we report an unusual case of splenogonadal fusion that was pre-diagnosed as a solid testicular mass in a patient who underwent orchiectomy.

Rarely rheumatological features may dominate and is the cause of missed or delayed diagnosis of a malignant lesion. A case is presented wherein the patient with embryonal type of testicular tumour masqueraded with symmetrical polyarthritis with small joint involvement. p53 antigen was detected in testicular tissue. Such an example is indeed unreported in literature to the best of our knowledge.

INTRODUCTION Rare foci of sperm production may be found in up to 60% of men with nonobstructive azoospermia (NOA). Sperm production, if present, is minimal for sperm appearance in the ejaculate. Given that there are no treatment options to restore fertility, sperm retrieval is the only alternative to find testicular sperm than then can be used for in vitro fertilization (IVF). Among sperm acqui...

Background: Vasectomy is a simple and highly effective contraceptive method with a low morbidity rate and an extremely low mortality rate. during the past decade millions of men have undergone vasectomy, but there have been surprisingly few studies of morphological effects of genital organs after vasectomy. The most important issues about vasectomy are degenerative changes in testicular tissue,...

OBJECTIVES : The pathophysiology of the testicular damage in varicocele have not been completely understood. There are several studies concerning the effects of increased seminal reactive oxygen species (ROS) and the role of nitric oxide (NO) in infertile patients with varicocele and antioxidants have been used successfully to decrease oxidative stress in testis. In this study, we determined th...

OBJECTIVE Vasectomy, though in some cases are being confronted with irreversibility, has been accepted as an effective contraceptive method. It is estimated that near 2-6% of vasectomised men ultimately show a tendency to restore their fertility. In some cases, vasectomy has been considered as an irreversible procedure due to many post-vasectomy complications causing this debate. The aim of pre...
