Artificial Testicle to Make Sperm For Infertile Men
Reconstituting Mammalian Spermatogenesis Using Stem Cells (Review).
Objectives Stem cells have the ability to both differentiate into other mature cell types and maintain an undifferentiated state by self-renewal. Currently, embryonic stem cells are the best studied stem cell type. Among adult stem cells, emerging research has focused on evaluating the pluripotency potential of testis stem cells. This review summarizes our current scientific understanding of the creation, assessment and clinical potential of testis-derived stem cells. Design Retrospective review … Continued
As the field of assisted reproduction has advanced, many previously untreatable men are now biological fathers. Although finding sperm in men with obstructive azoospermia is not difficult, locating and retrieving spermatozoa in men with non-obstructive azoospermia remains a clinical challenge, largely because sperm production in these men can be patchy or focal in nature. In response to this challenge, strategies such as fine-needle aspiration (FNA) mapping have been developed to find spermatozoa. This … Continued
