Objective This research was designed to induce an experimental varicocele model by a simple surgery in dog with minimum invasion and to investigate the expression of many genes (HSP90, HSP70, IL-4, TNF, KITLG and KIT receptor) involved in the varicocele-induced infertility. MaterialsAndMethods In this completely randomized design study, 6 adult dogs were used for this experiment. In one testis ...

Objective- To study a method of chemical sterilization and its efficacy in adult male dogs. Design- Experimental study. Animals- Ten healthy adult mixed breed dogs Procedures- Eugenia caryophyllata (EC) essential oil was injected into the dorsal cranial portion of each testicle of five dogs (treatment group). The same volume of normal saline was injected in the same site of testicles in the ...

Spermatogonial stem cell transfer has been studied in various species and suggested potential for success. Bull, stallion, donkey, mule, boar, dog and cat testicles were examined using various injection techniques to determine distribution patterns of injected material most favorable for stem cell transfer. Spermatogonial stem cells were recovered from freshly harvested stallion testicles using...

BACKGROUND AND OBJECTIVE Preoperative imaging techniques may guide management of nonpalpable, cryptorchid testicles. We evaluated conventional MRI for identifying and locating nonpalpable testicles in prepubescent boys via meta-analysis. METHODS Databases including Medline were searched from 1980 to February 2012. Eligible studies included ≥10 boys with cryptorchidism/suspected cryptorchidism...

Traditional Chinese medicine (TCM) has been increasingly practised in many countries of the world. Some recent textbooks of TCM still recommend formulas containing various animal tissues such as tiger bones, antelope, buffalo or rhino horns, deer antlers, testicles and os penis of the dog, bear or snake bile. Usually, animal tissues are combined with medical herbs. In most of the cases, the med...

OBJECTIVE The cryptorchidism is a risk factor for testicular cancer and is associated with cancer in the contraleteral testicle. The mechanism that leads to an increased risk of causes in a cryptorchid testis is unclear. MATERIALS AND METHODS We analyzed 25 patients of 20-years old for maldescended testicles we practiced orchiectomy in 22 testicles and orchiopexy in 7 testicles. The time pati...

The aim of this study was to evaluate the possible development of histological abnormalities such as fibrosis and microcalcifications after sperm retrieval in a ram model. Fourteen testicles in nine rams were exposed to open biopsy, multiple TESAs, or TESE, and the remaining four testicles were left unoperated on as controls. Three months after sperm retrieval, the testicles were removed, fixed...
