Been thinking about it lately, and will share these thoughts and ideas with you all. Been thinking about how a woman's embryo is capable of being used as stem cells...and weather or not semen can be used as stem cells within itself. Here is what I found. Respectfully...it takes about 3 months for sperm to fully mature So technically...after 3 months when sperm matures (become adults) they would then be able to morph into stem cells. If that is the case...then would it be assumed that these cells are then distributed through the body where needed to mature into cells into our bones, muscles, nerves, organs, tissues, etc.
