Abstinence before a date to increase testosterone, does this work?

Interestingly...: Yes, it does work according to a 2003 study. Testosterone levels were highest (compared to baseline) 7 days after ejaculation, if one remains abstinent during that time period. Here's the synopsis of the study: http://www.ncbi.nlm.nih.gov/pubmed/12659241

Why do you ask?: Every guy knows that the longer you wait between ejaculations, the hornier you get. How much this has to do with plasma testosterone, and how much simply with fluid volume and pressure, are really moot. An abstinent man may have an incredible performance, have premature ejaculation, or may end up with very sore testicles if he stays excited for long.
