Chromothripsis, a hallmark of cancer, is characterized by extensive and localized DNA rearrangements involving one or a few chromosomes. However, its genome-wide frequency and characteristics in urothelial carcinoma (UC) remain largely unknown. Here, by analyzing single-regional and multi-regional whole-genome sequencing (WGS), we present the chromothripsis blueprint in 488 UC patients.

Background: Platinum-based chemotherapy provides curative treatment to more than 95% of patients with testicular germ cell tumor but it has negative cardiometabolic and neurological effects. Regular exercise can alleviate late chemotherapy-related toxicities. We examined the impact of a 6-month supervised aerobic-strength training on cognitive and cardiometabolic health and residual level of platinum in cancer survivors.

Oligoasthenoteratozoospermia (OAT) is a frequent but severe type of male infertility. As one of the most multifaceted male infertility resulting from sperm problems, its genetic etiology remains unknown in most cases. In this review, we systematically sort out the latest literature on clinical reports and animal models leading to OAT, summarise the expression profiles of causative genes for OAT, and highlight the important role of the protein transport system during spermiogenesis, spermatid cell-specific genes, Golgi and acrosome-related genes, manchette-related genes, HTCA-related genes, and axoneme-related genes in OAT development.

Introduction to androgenetics: terminology, approaches, and impactful studies across 60 years.

Andrology

January 2025

Chair of Human Genetics, Institute of Biomedicine and Translational Medicine, University of Tartu, Tartu, Estonia.

Across six decades, androgenetics has consistently concentrated on discovering genetic causes and enhancing the molecular diagnostics of male infertility, disorders of sex development, and their broader implications on health, such as cancer and other comorbidities. Despite vast clinical knowledge, the training of andrologists often lacks fundamental basics in medical genetics. This work, as part of the Special Issue of Andrology "Genetics in Andrology", provides the core terminology in medical genetics and technological advancements in genomics, required to understand the ever-progressing research in the field.

Background: Androgen deprivation is associated with erectile dysfunction (ED). In different animal models, sulfur dioxide (SO) donors NaSO and NaHSO reduced oxidative stress, fibrosis, and inflammation which contribute to the pathogenesis of androgen deprivation-induced ED, however the effect of SO donors on ED in castrated rats were not known.

Objective: To investigate the therapeutic effect of SO donors, NaSO/NaHSO, on ED in castrated rat model.

Background: Asthenozoospermia, characterized by reduced sperm motility, is a common cause of male infertility. Multiple morphological abnormalities of the sperm flagella (MMAF) represent a severe and genetically heterogeneous form of asthenozoospermia. Over 50 genes have been associated, but approximately half of MMAF cases remain unexplained.

Background: 6-Nitrodopamine (6-ND) released from rat vas deferens acts an endogenous modulator of vas deferens contractility.

Objectives: To investigate whether rat isolated seminal vesicles (RISV) releases 6-ND, the mechanisms involved in the release, and the modulatory role of 6-ND on tissue contractility.

Methods: Rat seminal vesicles were removed and placed in Krebs-Henseleit's solution at 37°C for 30 min, and an aliquot was used to analyze the concentrations of 6-ND, dopamine, noradrenaline, and adrenaline by liquid chromatography with tandem mass spectrometry (LC-MS/MS).

Department of Urology, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, Hubei, China.

Background: Heterogeneous nuclear ribonucleoprotein M (HnRNPM) is a key splicing factor involved in various biological processes, including the epithelial‒mesenchymal transition and cancer development. Alternative splicing is widely involved in the process of spermatogenesis. However, the function of hnRNPM as a splicing factor during spermatogenesis remains unknown.

Department of Integrative Medicine and Andrology, Zhongda Hospital, School of Medicine, Southeast University, Nanjing 210009, China. Electronic address:

Ethnopharmacological Relevance: Diabetic erectile dysfunction (DED) is a prevalent but often overlooked microvascular complication of type 2 diabetes mellitus (T2DM), with strong associations to cardiovascular disease. The pathophysiology of erectile dysfunction (ED) in T2DM patients is more intricate than in non-diabetic individuals, likely involving multiple pathogenic mechanisms such as endothelial dysfunction, vascular alterations, neuropathy, and oxidative stress. Traditional Chinese Medicine (TCM) has long been utilized in the management of DED, drawing on an extensive body of clinical experience.

The most severe form of male infertility is idiopathic non-obstructive azoospermia (NOA), a complete sperm absence in the ejaculate. We performed exome sequencing in the Croatian infertile brothers with NOA and found a variant in DMRT1 (Doublesex and mab-3 related transcription factor 1) gene that was further assessed by the EMSA assay and molecular dynamic simulations. We additionally screened for DMRT1 mutations in 1940 infertile men diagnosed with spermatogenic failure, 644 normozoospermic controls, and 105 females with primary ovarian insufficiency (POI) recruited to the GEnetics of Male INfertility Initiative (GEMINI) or Estonian Andrology (ESTAND) cohorts.

Introduction: Retrograde ejaculation (RE) consists of the reflux backwards, towards the bladder, of the ejaculate, during the emission phase of ejaculation, causing a total or partial absence of sperm emission, with the consequent diversion of semen into the bladder during the emission phase of ejaculation. Evaluating the ejaculate may not be sufficient for identifying RE in some patients. Hence, the management of infertility may involve the use of invasive methods such as epididymal fluid retrieval or testicular biopsy.

Urachal cancer (UrC) is a rare disease which is mostly diagnosed late due to symptoms caused by its local invasion to the urinary bladder. Given the lack of clinical trials and guideline recommendations for systemic treatment, a molecularly informed precision oncology approach is a viable option for UrC already in the early lines of systemic treatment. While single case experiences may provide valuable reference for later decision-making, well-documented clinical experience with off-label targeted treatments is limited to a few patients.
