Fertility technology is now so advanced that a single sperm can theoretically solve fertility problems, and many men with infertility have the potential to obtain their own offspring. Very few men whose testes do not produce sperm can be treated with sperm from a sperm bank through artificial insemination to solve their fertility problems.
