1. Semen quality from patients affected by seminomatous and non-seminomatous testicular tumor
ABSTRACT Testicular cancer is considered a rare disease affecting approximately 1% to 2% of the male population. This neoplasm has a cure rate of over 95%; as a result, a major concern is the future of fertility of carriers from this disease. There are several histological subtypes of testicular tumors; however, the Testicular Germ Cell Tumors (TGCTs), compr

2. Use of testicular tone and echogenicity in identifying boars with low sperm quality
RESUMO O estudo objetivou avaliar o uso de características testiculares para identificar reprodutores com baixa qualidade de morfologia espermática. A consistência (escore de 1 a 5), o tônus por tonometria (mm), a ecogenicidade e a heterogeneidade do parênquima testicular por ultrassonografia (pixel) foram avaliados em 402 machos suínos maduros (18,5 m

3. Quality control and characterization of the testicles and ovaries of irradiated Anastrepha obliqua from Brazil
ABSTRACT: With the aim of making the application of the Sterile Insect Technique (SIT) feasible in the management of the West Indian fruit fly in Brazil, Anastrepha obliqua (Macquart) (Diptera: Tephritidae), a number of quality parameters required by the SIT were investigated in this study. The aim was to verify the influence of a range of doses of gamma rad

4. Protective Effect of Rosa Canina Extract Against Doxorubicin-induced Testicular Toxicity in Mice
Abstract The present study was aimed to investigate the in vivo effects of Rosa canina extract on doxorubicin-induced testicular toxicity in mice for the first time. Male NMRI mice were randomly divided into six treatment groups (10=per group) as follows: (I) vehicles, (II) doxorubicin alone (3 mg/kg, i.p. on days 7, 14 and 21), (III and IV): Rosa canina ext

5. Effect of an Organic Trace Mineral Premix on the Semen Quality, Testicular Morphology and Gene Expression Related to Testosterone Synthesis of Male Broiler Breeders
ABSTRACT In order to investigate the effect of organic trace minerals premix (OTM) on the reproductive performance of breeder roosters, a total of 240 San Huang roosters (23 weeks of age) were randomly divided into two treatments with six replicates of 20 roosters each. The first group (n = 120) was fed a basal diet containing an inorganic trace minerals pre

6. Antioxidant enzyme profile and lipid peroxidation products in semen samples of testicular germ cell tumor patients submitted to orchiectomy
ABSTRACT Purpose To determine enzymatic antioxidant and lipid peroxidation levels in seminal plasma of patients orchiectomized for testicular tumors. Materials and Methods The study included 52 patients: 26 control men and 26 orchiectomized patients for testicular tumor, of which 12 men had seminoma tumor and 14 men non-seminoma tumor. After semen analys

7. Sperm Quality and Testicular Histomorphometry of Wistar Rats Supplemented with Extract and Fractions of Fruit of Tribulus terrestris L.
ABSTRACT The aim of this study was to assess the sperm quality and testicular histomorphometry of Wistar rats supplemented with extract and fractions of fruits of Tribulus terrestris L. The ethanolic extract was obtained by dynamic maceration of spray-dried fruit. This extract was fractionated by liquid-liquid partition, using increasing polarity solvents. T

8. Metabolic and Testicular Effects of the Long-Term Administration of Different High-Fat Diets in Adult Rats
ABSTRACT Purpose: To evaluate the effects of different high-fat diets on body mass, carbohydrate metabolism and testicular morphology in rats seven months old.
Materials and Methods: Male Wistar rats were divided into four groups: SC (standard chow), HF-S (high fat diet rich in saturated fatt

9. Semen and reproductive parameters during some abstinence periods after cigarette smoke exposure in male rats
Cigarette smoking is very widespread globally and can also be implicated in male and female infertility. This study aimed to evaluate the testicular function throughout a complete spermatic cycle during abstinence from cigarette smoke exposure in order to identify a possible residual damage and whether the parameters could recover spontaneously. Male Wistar

10. Hypogonadotropic Hypogonadism Revisited
Impaired testicular function, i.e., hypogonadism, can result from a primary testicular disorder (hypergonadotropic) or occur secondary to hypothalamic-pituitary dysfunction (hypogonadotropic). Hypogonadotropic hypogonadism can be congenital or acquired. Congenital hypogonadotropic hypogonadism is divided into anosmic hypogonadotropic hypogonadism (Kallmann s

11. Efeitos do inseticida endossulfam sobre a morfologia e a morfometria testicular em morcegos frugívoros Artibeus lituratus (OLFERS, 1818) / Effects of the endosulfan on the testicular morphology and morphometry in fruit bats Artibeus lituratus (OLFERS, 1818)
Large amounts of agricultural chemicals are discharged into the environment in Brazil. These pesticides are often used to destroy or impair the activity of organisms that attack crops. There are some reports in the literature concerning the decline of many wildlife populations as a result of contamination of their habitats by pesticides. One of the putative

12. Morfofisiologia do sistema genital masculino de ratos púberes e adultos após privação androgênica durante a pré-puberdade / Morphophysiology of male reproductive system of adult and pubertal rats after androgen deprivation during prepuberty
Endocrine disrupters are chemicals that can act as agonists or antagonists of endogenous hormones, interfering with the homeostasis of the organism. Since the endocrine system plays a critical role in the development and function of the male reproductive system, this is an especially vulnerable target of potential endocrine perturbations. The literature pres
