Effects of chronic mild stress induced from peripuberty on sexual behavior in male rats, with or without escitalopram treatment.

Background: After the Coronavirus Disease pandemic, depression became more present, including in adolescents. Escitalopram, a selective serotonin reuptake inhibitor, was approved in 2009 for treatment of the major depressive disorder, both in children and adolescents. The undesirable effects of antidepressants on sexual dysfunction are usually underestimated.

Effects of escitalopram treatment and chronic mild stress induced from peripuberty on spermatic parameters of adult rats.

Background: The prevalence of depression in adolescents has significantly increased worldwide. Escitalopram is a selective serotonin reuptake inhibitor approved for treatment of psychiatric disorders in children and adolescents by the Food and Drugs Administration.

Aims: This study aimed to evaluate the sperm parameters of adult rats exposed to chronic mild stress (CMS), from peripuberty to adulthood, treated or not with escitalopram.

Increased sperm deoxyribonucleic acid damage leads to poor embryo quality and subfertility of male rats treated with methylphenidate hydrochloride in adolescence.

Background: Methylphenidate hydrochloride (MPH) is a psychostimulant widely used in the treatment of attention-deficit hyperactive disorder (ADHD), as well as a performance enhancer, for at least 60 years. Despite the notable effectiveness as a psychostimulant, ADHD is a chronic disorder and has a two-third chance of accompanying the individual throughout life. Long-term use of MPH has been associated not only with an increase in the development of neurodegenerative diseases, but it also causes side effects on male fertility in experimental animals.

Resveratrol benefits on sperm DNA, chromatin structure and reproductive outcomes of varicocelized rats.

In varicocele, the main cause of sperm DNA damage is oxidative stress (OS). Resveratrol, a polyphenol with antioxidant properties, can protect cells from injuries caused by OS. We investigated the benefits of resveratrol against reproductive damage caused by experimental varicocele induced from peripuberty.

Resveratrol improves sperm DNA quality and reproductive capacity in type 1 diabetes.

Background: In the coming decades, diabetes mellitus might affect 628 million individuals. Its final impact on male fertility and reproductive outcomes should be considered since the number of adolescents and young adults presenting diabetes is rising. Resveratrol (RES), a polyphenol, is a biological modulator with multitarget and multi-action characteristics.

Sertoli Cell Alterations in Peripubertal Varicocelized Rats: Evidence of Primary Damage on Spermatogenesis.

Idiopathic varicocele is closely associated with male infertility or subfertility. Sertoli cell is a very important regulator of spermatogenesis. We investigated the morphofunctional alterations in the Sertoli cell and its possible involvement in the establishment of testicular primary lesion in experimental left-sided varicocele, induced from peripuberty.

Resveratrol attenuates reproductive alterations in type 1 diabetes-induced rats.

The progression of diabetes mellitus leads to several complications including overproduction of reactive oxygen species and reproductive alterations. As resveratrol (RES) is a powerful anti-oxidant and an anti-apoptotic compound, we hypothesized that side effects of type-1 diabetes (DM1) on male reproduction could be reduced by the RES treatment. Eighty-four prepubertal male rats were distributed into seven groups: sham-control (SC), RES-treated (R), resveratrol-vehicle-treated (RV), diabetic (D), diabetic-insulin-treated (DI), diabetic-RES-treated (DR), diabetic-insulin and RES-treated (DIR).

Resveratrol improves reproductive parameters of adult rats varicocelized in peripuberty.

The aim of this study was to investigate the protective action of resveratrol against the reproductive damage caused by left-sided experimental varicocele. There was a reduction of testicular major axis in the varicocele group when compared with the other groups; the testicular volume was reduced in varicocele group in comparison to the sham-control and resveratrol groups. The frequency of morphologically abnormal sperm was higher in varicocele and varicocele treated with resveratrol groups than in sham-control and resveratrol groups.
