Dr. Hall sent me information on their progress with the sugar pill.

"With regards to our current research efforts on male contraceptive
development, we have found that Hex-B is one of several enzymes and
proteins involved in the fertilization process. We are currently
developing inhibitors to block the action of these enzymes and proteins to
research 100% efficacy. Currently, we testing to determine whether these
compounds carcinogenic, mutagenic, and their level of toxicity, if any.

Recently (2002), a competing group in England has verified our nonhormonal
approach of using amino sugars as potential male contraceptives (see
research article: Proceedings of the National Academy of Sciences[PNAS],
vol. 99, no. 26, pp. 17173-17178). We are working hard to patent our
products before our competitors and anticipate data from a "small" human
clinical trail in two years, if all goes well and according to plan."

Also, the PNAS article points out that for the chemical they are studying,
NB-DNJ, it has already been through clinical trials for two different
diseases at higher doses than is needed for contraceptive effect.
