25. Crossover transseptal vasovasostomy: alternative for very selected cases of iatrogenic injury to vas deferens
ABSTRACT Inguinal herniorraphy is a possible cause of iatrogenic seminal tract obstruction. Diagnosing and correcting these vasal injuries can be challenging. Successful re-anastomosis is technically challenging, with relatively low success rates. An uncommon alternative for selected cases is the crossover transseptal vasovasostomy. We herein report a case o

26. Urotrema macrotestis and Urotrema scabridum (Digenea: Urotrematidae) parasitizing bats (Mammalia: Chiroptera) in Brazil
Urotrema scabridum Braun 1900 and Urotrema macrotestis Mané-Garzón and Telias 1965 are reported from the small intestine of Eumops glaucinus (Wagner, 1843). The species were differentiated by the body width, the size and position of acetabulum, the size of testis, the caecal termination, and the distribution of vitellarium. The present study expands the di

27. Solexa Profiling Identifies Differentially Expressed MiRNAs Between Sexually Immature and Mature Equine Testis
ABSTRACT MicroRNAs (miRNAs) are a class of short non-coding RNAs identified as potent regulators of gene expression. Previous studies have suggested that miRNAs are involved in mammalian spermatogenesis. Stallion fertility is an important trait for the horse breeding industry, but stallion fertility traits are largely ignored in the industry. In this study,

28. Morphological changes of gonad and gene expression patterns during desexualization in Dugesia japonica (Platyhelminthes: Dugesiidae)
ABSTRACT Planarians, the representatives of an ancient bilaterian group with complex reproductive system and high regenerative capabilities, are model system suitable for studying the basic molecular requirements for the development of the reproductive system. To further explore the morphological changes of the gonads during desexualization and the molecular

29. Mercury Biodistribution in Rats after Chronic Exposure to Mercury Chloride
This study aimed to evaluate the distribution of mercury in rats after controlled chronic exposure to three different doses of HgCl2 for 30 days. Samples of blood, brain, liver, testis, heart, and kidneys were collected for mercury determination. Although the rats were exposed to different doses, the Hg levels in blood were similar among the groups under stu

30. Bilateral testicular torsion in an adolescent: a case with challenging diagnosis
ABSTRACT Bilateral testicular torsion is a very uncommon emergency, with a challenging differential diagnosis. We describe the case of a 15-year-old patient with a left testicular torsion of 48 hours of duration and a sudden onset of right scrotum pain during his stay at the emergency area. Bilateral testicular torsion was diagnosed after repeat physical exa

31. Investigation of the antioxidant effects of pheniramine maleate and nebivolol on testicular damage in rats with experimentally induced testis torsion
Abstract Purpose: To investigate the biochemical, histopathologic, and spermatogenetic changes in the detorsionated testicle after experimental torsion and to study the antioxidant effects of pheniramine maleate and nebivolol. Methods: Twenty-four Sprague-Dawley male rats were divided into 4 groups: Group 1: Sham; Group 2: Torsion/Detorsion (T/D); Group 3

32. Effect of Transient Treatment with Propylthiouracil on Some Reproduction Traits and Live Weight of Japanese Quails
ABSTRACT This study was conducted to investigate the effects of transient treatment with propylthiouracil (PTU) on some reproduction traits and live weight of quails. The trial lasted 8 weeks. To accomplish this goal, 700 1-day-old quail chicks were used, randomly divided into 8 groups. PTU was added to feed by 0.1% and 0.5% /wt. The first 4 groups had 0.5%

33. Medical ozone therapy reduces oxidative stress and testicular damage in an experimental model of testicular torsion in rats
ABSTRACT Objective: Testicular torsion (TT) refers to rotation of the testis and twisting of the spermatic cord. TT results in ischemia-reperfusion (I/R) injury involving increased oxidative stress, inflammation and apoptosis, and can even lead to infertility. The aim of this study was to investigate the effect of ozone therapy on testicular damage due to I

34. Aggravation of cyclophosphamide-induced reproductive toxicity in mice by aqueous extract of Aegle marmelos (L.)
ABSTRACT Aegle marmelos (L.) (Rutaceae) commonly known as bael is an important medicinal fruit tree. The present study focused on the effects of aqueous extract of Aegle marmelos (AEAM) on the testis and sperm characteristics induced by cyclophosphamide (CPA) in mice. Thirty six adult Parke’s strain mice were divided into six groups: group I given only dis

35. Negative effects of bisphenol A on testicular functions in albino rats and their abolitions with Tribulus terristeris L.
ABSTRACT This study was conducted to find out the ameliorative properties of Tribulus terristeris L (TT) on BPA induced spermatotoxicity in male albino rats. Mature male albino rats were divided into five groups, Group A was taken as control for comparison group, whereas the other four groups namely B(vehicle control), C (toxic), D (preventive control) and G

36. Molecular analysis of CIB4 gene and protein in Kermani sheep
The human calcium- and integrin-binding protein (CIB) family is composed of CIB1, CIB2, CIB3, and CIB4 proteins and the CIB4 gene affects fertility. Kermani sheep is one of the most important breeds of Iranian sheep breeds. The aim of this study was to analyze for the first time molecular characteristics of the CIB4 gene and protein in Kermani sheep. Differe
