How It Works: The latest, and most
successful, version involves careful
dosages of two different hormones. The
first is progesterone, a chemical that
also is a big player in most female birth
control pills. Increasing a guy’s
progesterone levels will shut off sperm
production, but also leads to awkward side
effects—like acne or weight gain.
Regular doses of testosterone counteract
this.
It’s taken under the skin. According to
researcher Regine Sitruk-Ware, the
Population Council Center for Biomedical
Research is working on a way to deliver
the necessary doses in one or two yearly
implants.
Likelihood You’ll Live to See It: High.
Hormonal birth control has been in the
works for a long time. A pharmaceutical
company called Organon had a version in
the final stages of clinical trials last
year, but opted to drop it after the
delivery method (implant and regular
injections) proved too inconvenient.
Method: RISUG.
How It Works: Essentially a reversible
vasectomy, the Reversible Inhibition of
Sperm Under Guidance system involves one
simple injection into the vas deferens,
the tube that sperm travel through on
their way from the testes to the urethra.
The shot delivers a dose of a compound
that blocks up the tube and breaks apart
the cell membranes of any sperm that try
to sneak past.
Likelihood You’ll Live to See It: Very
high, particularly in India. RISUG is set
to begin Phase III clinical trials in
India this month. Studies in the U.S. and
eventual FDA application may follow."
Method: Dry orgasm pill.
How It Works: Just like it sounds, the dry
orgasm pill would chemically prevent the
involuntary muscle movements that get
sperm and the rest of the ingredients of
semen into (and out of) the urethra.
According to Kirsten Thompson of the Male
Contraception Coalition, because this
method prevents the passage of bodily
fluids it has the potential to replace the
condom—preventing both pregnancy and STD
exchange.
Likelihood You’ll Live to See It: Mid to
low. The basics of the pill were only
discovered in November 2006. This method
still has a long way to go before it even
gets to clinical trials."

COol stuff
I don't think the "dry-orgasm" one will be
very popular anyway because isn't the
actual ejaculation a major part of the
enjoyment for a manw ho is orgasming?
