Andrology, EarlyView.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.

Andrology, EarlyView.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 ...

Andrology, EarlyView.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 ...

Cryopreservation of Embryos: An Overview
, 2010 Cryopreservation (liquid nitrogen, -196°C) is the only safe and cost-effective option for long-term -conservation of genetic resources of non-orthodox seed species. Cryopreservation protocols have been developed for various materials including seeds, dormant buds, cell suspensions, calli, apices, zygotic, and somatic embryos of numerous plant species ...

Examples of Integration of Cryopreservation in different Plant Biotechnology Programmes
, 2008 Cryopreservation appears as an alternative to the preservation of biodiversity due to the risks to lose a part of the genetic resources by climatic disaster, human activities, pests and diseases.
