Objective: Testicular tumours are rare in paediatric patients, accounting for only 1% of tumours in boys. Leydig cell tumours are the most common gonadal stromal tumours. Since these tumours are functionally active, secreting testosterone, they characteristically produce isosexual pseudoprecocious puberty (IPP), the customary therapeutic choice being radical orchiectomy. Nowadays, considering that Leydig cell tumour in boys are invariably benign, some authors suggest a more conservative choice of therapy.
Methods: This article presents the case of a patient with a cytological and immunohistochemical diagnosis of Leydig cell tumour with no clinical symptoms of IPP. The treatment carried out was enucleation of the tumour through a transcrotal access with subsequent follow-up monitoring.
Results: After 2 years of follow up the patient remains free of symptoms and shows a degree of sexual development corresponding to his age.
Conclusions: We consider enucleation of the tumour to be a safe and effective therapy as an alternative to radical orchiectomy.

Sulfur dioxide (SO) is a ubiquitous environmental pollutant that has been shown to be toxic to the male reproductive system, but the underlying mechanism remains unclear. Therefore, the SO-treated mice and primary Leydig cell models were established to investigate the effects of SO on the production of testosterone and its specific mechanism. The results demonstrated that SO activated the ERK1/2 signaling pathway, leading to increased key proteins expression of testosterone biosynthesis and elevated testosterone levels.

4-Cyano-4'-ethoxybiphenyl (EBCN) is a representative cyano liquid crystal monomer (LCM). While prior studies have documented the widespread occurrence of LCMs in diverse environmental and biological samples, research on their reproductive effects in vivo remains limited. This study employed 35-day and 70-day exposure models in mice to assess the short-term and long-term effects of environmentally relevant concentrations of EBCN on testicular health.

Crude oil contamination has been shown to impair reproduction in aquatic animals through carcinogenic and genotoxic properties. Here, we assessed the endocrine-disrupting function of crude oil on male reproductive system based on testicular histology, sex steroid hormones, and fertility endpoints in adult male goldfish (Carassius auratus), which were exposed to 0.02- to 2-mg/L crude oil for 21 days (Experiment #1) or to 5- to 250-mg/L crude oil for 9 days (Experiment #2).

As a novel organophosphate ester (NOPE), tris(2,4-di-butylphenyl) phosphate (TDtBPP) has attracted significant attention due to its unexpectedly high detection in natural environments. However, the ecological toxic effects of environmentally relevant concentrations of TDtBPP in organisms remain entirely unknown. In this study, 1 month old zebrafish were exposed to 0, 50, 500, or 5000 ng/L TDtBPP for 150 days, and the reproductive toxicity in male fish was evaluated.

Lepidium meyenii (Maca) is a plant that has nutritional benefits and increases the effectiveness of male reproduction. In this study, oxidative stress-exposed New Zealand rabbits were used to assess the ameliorative effects of daily Maca ingestion on testicular and epididymal tissues as well as the quality of fresh and frozen/thawed sperm. Twenty-four 40-week-old, healthy New Zealand white male rabbits were divided into four groups.
