Is Tribulus Terrestris Safe During Pregnancy?
T. terrestris has never been studied in pregnant humans, so it is impossible to know for sure if it is safe (or unsafe) for use during pregnancy. However, studies in sheep suggest that it might negatively affect the development of the fetal brain. Furthermore, T. terrestris is often claimed to increase testosterone and other male hormones; if this is indeed the case (and it may not be), the supplement could negatively affect a pregnancy (especially with female fetuses). Testosterone (and substances that increase testosterone) can cause masculinization of genitalia in female fetuses.
