Background: It is known that vanadyl compounds are capable of alleviating hyperglycemia in streptozotocin induced diabetic rats. Objective: To examine the effect of vanadyl sulphate (VS) on spermatogenesis of male rats. Methods: Male rats (n=10) were administered 32 mg/kg/day of VS orally and 50 mEq/l NaCl (as drinking water) for one month.  Meanwhile, 11 male rats, the control group, received ...

Background: Fluoxetine (FLX) is a selective serotonin reuptake inhibitors antidepressant. FLX affects chemicals in the brain that may become unbalanced and cause depression, panic, anxiety, or obsessive-compulsive symptoms. Black Grape seed extract (BGSE) antioxidants neutralize free radicals and oxidative stress. Therefore this study was designed to investigate Protective effect of RGSE hydroa...

Background: Fluoxetine (FLX) is an Antidepressant compound. FLX produces undesired side effects including anxiety, sleep disturbances, sexual dysfunction and gastrointestinal disturbances. The grape is a significant source of nutritional antioxidants, such as polyphenols, anthocyanins, flavonids as well as biologically active dietary components. Present study was performed to investigate the pr...

Background: The purpose of this study was to determine whether 50 days of forced swimming stress applied to adult male rats affects count, motility and fertilization capacity of sperm Materials and Methods: A total 30 adult male wistar rats were used in this study. All rats were divided into two equal groups (n = 15): (1) control group and (2) experimental group. Animals of the experimental gro...

Background: Nowadays, cryoprotectant-free vitrification of human sperm in large or small volumes facilitated storage and use of human sperm for long time. However, this procedure was not successful in farm animals. The main finding in the studies is higher sensitivity of these kinds of sperm to sucrose osmolarities. Preliminary studies showed a reversible effect of sucrose on goat epididymal sp...

Males that follow alternative reproductive tactics might differ in their investment into testis development and sperm production. The resource-allocation hypothesis predicts that males following a sneaker tactic should invest more into sperm production than dominant territorial males which should invest more into mate guarding. This hypothesis is supported by studies in species where individual...

In the process of establishment of an inbred Duroc pig strain, males with size asymmetry of the testes were frequently observed. To clarify the possible causes of this asymmetry, we examined the testes and epididymides of 67 males of the F4-F7 generations at 35-100 weeks of age. Testicular weights showed a wide variation (120-610 g). When the weights of the testes were compared bilaterally, 35 ...

The aim of this study was to measure the serum AMH (anti-Mullerian hormone) concentrations in a group of boys with or without cryptorchidism, evaluation of karyotypes, testicular position, morphology, and major length of the undescended testes. Fifty boys who were 1-4 years old (median = 2.4 years) with unilateral cryptorchidism were evaluated. All of them underwent orchidopexy in 2010. Prior t...
