Tribulus (Tribulus terrestris) is also called puncturevine and has traditionally been used in China and India for infertility and ED. Recently its use has increased as a way of improving sports performance. Prior claims that Tribulus increases serum testosterone has not been substantiated by recent studies. One group found that after 4 weeks of Tribulus supplements at 10 to 20 mg/kg body weight daily, testosterone was unaffected [52].

In rat studies, the administration of Tribulus extract heightened sexual behaviour and resulted in increased ICP. The authors claimed that this effect was due to increases in testosterone [53]. For this reason, Tribulus is contraindicated in pregnant women and men with prostate cancer. It has also been found to be toxic in sheep, eventually leading to death [54], and there are reports of gynaecomastia in men taking Tribulus [55].
