All,

Please see the "Files" section for a file called "Implanon.pdf". It
it an article entitled "Suppression of Spermatogenisis by
Estonogestrel Implants and Depot Testosterone: Potential for Long-
Acting Male Contraception". It is written for medical people, but
though most of us on this list are not MD types, I could still
understand the gist of it.

I obtained the article by asking for more information from a
university in Scotland that is on the research forefront of this
issue. See:

http://news.bbc.co.uk/1/hi/health/836436.stm

for the article that led me to the University of Edinburgh, and:

http://www.obg.ed.ac.uk/CDN/

for the web site for the particular department. I asked the dr. who
sent me the .pdf for where I might find, if there is one, a web page
with press releases or updates on progress. But in his reply note to
me he said there was increased commercial interest in it so he hoped
that more research would be funded.

I'd say there's commercial interest. Perhaps 10,000 years worth of
pent-up demand!
