In general, serum testosterone rises immediately following resistance training in men, but returns to baseline, or even below baseline, after about 30 minutes.[1] In women, some studies have also found short-term increases in serum testosterone, but others haven’t, so the results are more equivocal.

Resistance training generally causes an immediate rise in serum testosterone levels in men; these levels then return to baseline or lower after approximately 30 minutes. In women, the effects are less consistent; some studies show short-term increases and others do not.
