Gut‐Derived Exosomes Mediate the Microbiota Dysbiosis‐Induced Spermatogenesis Impairment by Targeting Meioc in Mice

Advanced Science
Diseases like obesity and intestinal inflammation diseases are accompanied by dysbiosis of the gut microbiota (DSGM), which leads to various complications, including systemic metabolic disorders.

The constitutive 20S proteasome is required for the maintenance and differentiation of spermatogonia in mice

Journal of Advanced Research
Proteasomes undergo dynamic changes in their types and activities during mammalian spermatogenesis. While the spermatogenesis-specific 20S proteasome (s20S), characterized by PSMA8 substitution of PSMA7, is known to be essential for meiosis I completion,

Cryopreservation of Spermatozoa Prior and Post‐Orchiectomy in Patients With Testicular Germ Cell Cancer—Does the Timing Matter?

Andrology, EarlyView.
ABSTRACT Background Testicular germ cell cancer (TGCC) is the most frequent malignancy in young men of reproductive age. According to guidelines, semen cryopreservation should be performed prior to orchiectomy. Lack of time and local facilities as well as mental pressure are challenges in terms of fertility preservation before surgery.

Development of the membrane ceiling method for in vitro spermatogenesis

Scientific Reports
Spermatogenesis is one of the most complex processes of cell differentiation and its failure is a major cause of male infertility. Therefore, a proper model that recapitulates spermatogenesis in vitro has been long sought out for basic and clinical ...

A Review on Application of Three Dimensional Culture and Testicular Scaffolds to Induction of in-Vitro Spermatogenesis

Majallah-i Dānishgāh-i ’Ulūm-i Pizishkī-i Shahīd Ṣadūqī Yazd, 2020
Introduction: Induction of in vitro spermatogenesis can be useful for infertility treatment in azoospermic patients and those undergoing chemotherapy. Different culture systems have been used to achieve this goal. This review study was performed with the

Inhibition of HMGA2 Leads to Reduced Cell Proliferation and Increased Apoptosis in Human Embryonal Carcinoma Cell Lines

Andrology, EarlyView.
ABSTRACT Background The most prevalent solid tumors in young men are testicular germ cell tumors (TGCTs), and embryonal carcinoma is the most common subtype among non‐seminomatous germ cell tumors (NSGCTs). Despite the excellent cure rates of cisplatin‐based chemotherapy, resistance develops in 15%–30% of patients with metastatic cancer, which results ...

T Cell Microenvironmental Impacts and Therapeutic Opportunities: Application to Human Testicular Germ Cell Tumors

Andrology, EarlyView.
ABSTRACT Testicular germ cell tumors (TGCT) are the leading malignancy in adolescent and young adult males, yet the immunological and cellular mechanisms governing their tumor microenvironment (TME) remain poorly understood. Here, we present a comprehensive review of TGCT pathobiology with a focus on the immune landscape, particularly the role of tumor‐

Impact of Chemotherapy on Sperm Functional Characteristics in Patients With Testicular Germ Cell Tumours

Andrology, EarlyView.
ABSTRACT Background Testicular germ cell tumours (TGCT) are the most common malignancies among young men and represent a major threat to reproductive health. Both the disease itself and oncological treatments, particularly chemotherapy, can compromise spermatogenesis and semen quality.

Broader Familial Cancer Risk in Relatives of Testicular Cancer Patients: Insights From Two Mediterranean Populations

Andrology, EarlyView.
ABSTRACT Background Familial clustering of testicular germ cell tumour (TGCT) is well‐established, whereas the risk of non‐testicular cancer among relatives remains inconsistent across studies. Objective To evaluate the overall and site‐specific cancer risk among first‐degree relatives and grandparents of TGCT patients compared to cancer‐free controls.
