Summary: The study found that anogenital distance (AGD) is shorter in testicular cancer survivors compared to men from the general population, and that AGD is not affected by testosterone replacement therapy in adulthood. This supports the hypothesis that reduced AGD is part of the testicular dysgenesis syndrome and may be a marker of disrupted foetal testicular development.

Summary: Testicular cancer is a major cause of morbidity and mortality in young men worldwide, with different symptoms and associations with other serious conditions. Traditional treatments such as chemotherapy and surgery have limited effectiveness and negative impacts on life quality. Therefore, finding a new therapeutic candidate is crucial. Herbal remedies, including curcumin from Curcuma longa, have shown promise in treating testicular cancer.

Summary: The study utilized single-cell RNA sequencing to comprehensively assess the toxic effect of DEHP on testicular development. DEHP disrupted the developmental trajectory of germ cells, spermatogonial stem cells, Sertoli cells, Leydig cells, and peritubular myoid cells. The intercellular interactions and signaling pathways related to neurotrophic factors and growth factors were altered after DEHP treatment. These findings provide novel insights into the reproductive toxicity of DEHP.

Summary: Research has shown that impaired virilisation may occur in certain 46,XY individuals with defects in androgen synthesis or action, despite normal testicular development. A recent case study of a patient with complete androgen insensitivity syndrome (CAIS) revealed abnormal expression of HSD17B3 in Sertoli cells (SCs) and not in Leydig cells (LCs), suggesting a defect in testicular development and function. This study investigates the impact of altered androgen signalling in the gonads of five individuals with defects in androgen synthesis or action.

Summary: Testicular cancer has a high cure rate, with most patients diagnosed at a young age. Research into survivorship issues and newer biomarkers among testicular cancer patients and survivors will continue to advance the field. Further therapeutic options are needed for patients who do not respond to standard treatments.

Summary: This study analyzed the testicular microcirculation in Klinefelter syndrome (KS) using contrast-enhanced ultrasonography (CEUS) and found that KS patients have slower testicular blood flow dynamics compared to controls, with reduced venous blood flow independently predicting peripheral release of testosterone (T).

Summary: This review summarizes the attention given to environmental oestrogens (EEs) as environmental pollutants due to their impact on congenital malformation of the male genitourinary system. The mechanisms by which EEs exposure disrupts testicular descent, a highly orchestrated process essential to human reproduction and survival, are discussed. Identification of the components of the intricate cellular and molecular networks involved in testicular descent provides opportunities for preventing and treating EEs induced male reproductive dysfunction.

Summary: Testosterone replacement therapy (TRT) was evaluated for its impact on metabolic health in testicular cancer survivors. The study found that TRT did not improve metabolic health in patients with mild Leydig cell insufficiency. These findings do not support the routine use of TRT in this patient population.

Summary: Environmental chemical exposure may have negative effects on male reproductive health. A study using a sheep model found that male offspring from ewes exposed to biosolids treated pasture (BTP) during pregnancy showed testicular abnormalities, with increased expression of certain transcription factors. This suggests that gestational exposure to low-level mixtures of environmental chemicals can have long-lasting effects on testicular health, potentially affecting fertility.

Summary: This study analyzed the clinical features and pathological findings of the largest reported case series of testicular regression syndrome (TRS). The study found that TRS is more common on the left side and is usually accompanied by a closed internal ring and compensatory hypertrophy of the contralateral testis. Germ cells are only present in cases where the spermatic vessels enter the internal ring.

Summary: This study investigated the pathogenesis of CNS germ cell tumors (GCTs) using a combined transcriptomic and methylomic approach. The results showed that germinomas had gene expression profiles similar to primitive cells during early embryogenesis, while nongerminomatous GCTs (NGGCTs) had differentiated phenotypes. In addition, the tumor microenvironment balance played a crucial role in the development of GCTs. The findings of this study provide insights into the biology of GCTs and may contribute to future treatment development.

Summary: This study using a BTP sheep model found that gestational exposure to environmental chemical mixture led to decreased germ cells and increased Sertoli-cell-only seminiferous tubules in ram lambs' testes. Comparison with human TDS patients revealed common gene changes related to apoptosis and mTOR signaling. The activation and nuclear localization of HIF1 alpha were also observed in Leydig cells of BTP exposed animals, potentially disrupting testosterone synthesis.

The findings suggest that M371 levels can potentially aid in preoperative characterization of benign testicular tumours eligible for conservative surgery.

Summary: Cushing's syndrome (CS) affects the gonadotrope axis and testicular functions differently depending on the intensity of hypercortisolism and underlying etiology. Excess cortisol caused by CS leads to varying degrees of hypogonadotropic hypogonadism (HH), with more severe impairment in men with intense hypercortisolism associated with paraneoplastic/ectopic adrenocorticotrophic hormone (ACTH) secretion (EAS).

Summary: Using in vivo and ex vivo models, the study shows that PACAP-38 can provoke migraine-like changes independently of CGRP and partially through K-ATP channels. The findings suggest that PACAP-38 antagonism could be a potential alternative therapeutic approach for patients non-responsive to CGRP-targeting therapies.

Summary: Systemic administration of levcromakalim induced hypersensitivity, while central and local administration provided antinociception in mouse models. The Kir6.1 smooth muscle knockout mouse was protected from both GTN and levcromakalim induced hypersensitivity, suggesting a vascular contribution to hypersensitivity induced by migraine triggers.

Summary: The study found that while paracetamol itself does not affect Ca2+ signalling in human sperm, its metabolite AM404 interferes with sperm Ca2+ signalling and function through a CatSper-dependent action. This suggests a potential explanation for the negative association between urinary paracetamol concentrations in males and sperm motility.

The study showed that erenumab and rimegepant are potent antagonists of CGRP-R and AMY(1)-R with significantly higher preference for CGRP-R over AMY(1)-R.

Summary: This study investigated the effects of reduced androgen action during early human fetal testis development using an ex vivo tissue culture model. It found that manipulating androgen production during gestational weeks 7-14 affected the function and density of various cell types in the human fetal testis, similar to the effects observed in rats. This suggests the presence of a window of androgen sensitivity in the human fetal testis.

Summary: Metformin is a widely used medication for type 2 diabetes, but its reproductive effects on humans and wildlife remain unclear. Existing evidence suggests that the drug may impact hormone levels and fertility. Additionally, metformin is present in wastewater and drinking water, posing potential hazards to the environment and human health.
