This sounds like it is on the right track for a male conterceptive. I
would be willing to be a test subject in a trial if one was offered in
the Chicago land area. I have had chidren and now in my 50's and still
very fertile, so I was tool by my doctor when I rectly had a sperm
count done . This is a long time comming and I wish this would of been
closer in the 70's.

thanks,
Jimmy
