Yes. The abstract says you don't get significant elevations in T until the seventh day of abstinence. It then says T holds steady (at the elevated level). So, basically, the next ejaculation reduces T by 1/3 and you have to wait another week to get it elevated again. I searched PubMed for other research on this and couldn't find anything. But my PubMed searching skills are very weak. I didn't see anything in the abstract about the age of the sample population. If my interpretation of the data is correct, if you wanted elevated T, you would abstain for long periods of time. Or you could try Keebler's strategy and aim for orgasm without ejaculation. That way you could have your fun and your T too.
