OBJECTIVE To determine whether decreased testicular levels of enzymes necessary for retinoic acid biosynthesis were associated with male infertility, as retinoic acid is known to be necessary for spermatogenesis. DESIGN Observational analysis of testicular tissue samples, sperm indices, and serum hormone concentrations. SETTING Two infertility centers in Chile. PATIENT(S) 32 infertile men...

Background & Aim: Onosma stenosiphon has been used as herbal medicine for healing skin cuts and rashes. However, burn healing effect of this herb has not been yet reported in pharmaceutical texts. The aim of this study was to find out the effect of herb ointment on burn healing the superficial wounds post type II burns of back and testis region in Wistar rats. Experimental: A total of...

There are two main reasons why sperm may be absent from semen. Obstructive azoospermia is the result of a blockage in the male reproductive tract; in this case, sperm are produced in the testicle but are trapped in the epididymis. Non-obstructive azoospermia is the result of severely impaired or non-existent sperm production. There are three different sperm-harvesting procedures that obstructiv...

Aim: Olanzapine has adverse effects on sexual dysfunction. There are a limited number of studies showing that it also causes structural changes in the reproductive system. This study aimed to examine L-Carnitine testicular damage caused by terms histopathological, sperm parameters, biochemical aspects. 
 Method: A total 48 adult Sprague-Dawley male rats were used our study. Rats divided in...

Background The aim of this study was to determine oxidative stress (OS) parameters after testicular torsion/detorsion in adult rats. MaterialsAndMethods In this experimental study, male adult Wistar rats were divided into four groups, each consisting of seven animals: group I-one hour right testicular torsion with subsequent orchiectomy, group II-one hour right testicular torsion followed by de...

Despite its infrequent occurrence, testicular schistosomiasis forming pseudo-tumors can be considered in the differential diagnosis of testicular tumors, especially in areas where the parasitic disease is endemic. In this report, we present a case of testicular schistosomiasis caused by Schistosoma mansoni and mimicking a testicular neoplasm. We describe the patterns of a testicular nodule on u...

background fluoxetine (flx), a selective serotonin reuptake inhibitor, is widely used in the treatment of neurological disorders. however, its application carries the risk of adverse reactions, including reproductive toxicities. grape seed is highly regarded for its pharmacological activities, specifically its antioxidant properties. objectives this study was designed to evaluate whether hydroa...

BACKGROUND It has been demonstrated that brief episodes of sublethal ischemia-reperfusion, so-called ischemic preconditioning, provide powerful tissue protection in different tissues such as heart, brain, skeletal muscle, lung, liver, intestine, kidney, retina, and endothelial cells. Although a recent study has claimed that there are no protective effects of ischemic preconditioning in rat test...
