Research suggests that Cistanche and its constituent compounds may support testosterone levels and male reproductive function through several proposed mechanisms, including stimulation of testosterone-producing enzymes and modulation of hormonal feedback pathways in the hypothalamus, with one 2025 randomized controlled trial reporting favorable shifts in testosterone and cortisol ratios alongside strength gains in men undergoing resistance training. Studies include one small RCT, several animal studies, and one study examining a multi-herb topical preparation, with the majority pointing in a supportive direction for hormonal and reproductive outcomes. However, the evidence is meaningfully complicated by a 2012 mouse study finding that Cistanche herba caused dose-dependent reductions in testosterone and sperm count along with visible testicular damage, suggesting that species, preparation method, dose, and extract composition may matter considerably. Overall, the human evidence remains very limited and preliminary, the animal findings are mixed, and readers should weigh these factors carefully rather than drawing firm conclusions about Cistanche's effects on testosterone in people.
