ABSTRACT Background Klinefelter syndrome (KS) is characterized by marked phenotypic heterogeneity that might be influenced by genetic modifiers, including androgen receptor (AR) repeat length (CAGn and GGCn). The clinical relevance of these repeat lengths in patients with KS before testosterone replacement therapy (TRT) remains unclear.

Using Sperm Posthumously: National Guidelines Versus Practice
Under pressure from involved families and time limitations, Israeli judges tend to authorize postmortem sperm retrieval and freezing, even in unmarried men and in contradiction to current, albeit non-legally binding, guidelines of the Attorney General ...

ABSTRACT Background Genetic variability within the follicle‐stimulating hormone (FSH)‐related genes might contribute to phenotypic heterogeneity in patients with Klinefelter syndrome (KS), yet its clinical impact on sperm retrieval remains unclear. Objectives To investigate the association between FSHB c.211 G > T and FSHR polymorphisms (c.2039 A > G ...

ABSTRACT Background Sperm acquire fertility ability during epididymal maturation mainly in the epididymal caput and corpus, and once matured, are stored in the epididymal cauda. During storage, interactions with cauda epididymosomes (epEVs) may influence sperm fertility potential; however, the role of such interactions on sperm fertility remains ...

Objective To clarify the impact of chromosomal aberrations on the offspring of patients with testicular germ cell tumour (TGCT) by evaluating the outcomes of intracytoplasmic sperm injection (ICSI). Patients and Methods Under the ethical review of Yokohama City University, 12 patients with TGCT and 25 with non‐TGCT cancer who had cryopreserved sperm ...

Advancing conservation breeding programs for marine invertebrates
Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.
