Testes Articles

Testis-specific genes are essential for the spermatogenesis in mammalian male reproduction. In this study, we have identified a novel testis-specific gene,Ccdc136(coiled-coil domain containing 136), from the results of high-throughput gene expression profiling in the developmental stage of mouse testes.

The terms androgen deficiency, testosterone-deficiency syndrome and male hypogonadism have been used interchangeably. It is a clinical condition affecting a significant number of men in the US and worldwide, and is under-recognized and under-treated.

Impotentia generandi (IG) is a major problem in male dromedary camels. The objective of this research was to characterize the FSH, LH and testosterone profiles and their association with clinical findings and semen characteristics in IG-male dromedaries.

About one-fifth of couples has fertility problems in Western countries. Male factors are present in about half of them, either alone or in combination with female causes. Therefore, both partners should be evaluated simultaneously.

Male infertility is defined as the inability to conceive following 1 year of regular unprotected intercourse. It is the causative factor in 50% of couples and a leading indication for assisted reproductive techniques (ART).

PURPOSE - To present the clinical and histological features of prepubertal testicular tumors (PTTs), the long-term experience of a single institution was reviewed.

MATERIALS AND METHODS - A total of 62 prepubertal children who were treated for testicular tumors at Kanagawa Children's Medical Center from 1971 to 2014 were retrospectively reviewed.

The COVID-19 pandemic has led the international community to conduct extensive research into potential negative effects of the disease on multiple organs and systems in the human body. One of the most discussed areas is potential of the virus to compromise the testicular function.

Chronic stress is a major factor contributing to male infertility. Increasing evidence has demonstrated that resveratrol or dimethyl fumarate (DMF) has antioxidant and anti-inflammatory functions. Our study aimed to evaluate the protective effects of resveratrol or DMF against testicular dysfunction associated with chronic unpredictable mild stress (CUMS)-induced depression in rats.

Male factor accounts for about 30-50% of infertility. A common cause of male infertility is drug abuse; either illicit or prolonged use of prescribed drugs. This study provides a review of the physiology of the hypothalamic-pituitary-gonadal axis and recent literature on drugs that have been linked to male infertility and the associated mechanisms.
