Risk compounds, potential mechanisms and biomarkers of traditional Chinese medicine-induced reproductive toxicity.

With the increasing application of traditional Chinese medicine (TCM), TCM-induced reproductive toxicity has gradually aroused people's concern. Various TCM, such as Tripterygium wilfordii Hook. f., Radix Aconiti lateralis Preparata and Rhizoma Pinelliae, are currently reported to cause reproductive toxicity in humans and animals. However, a summary of the material bases, mechanisms and biological markers of TCM-induced reproductive toxicity is still lacking. This review filled the gap by searching and summarising relevant studies and articles published on PubMed, CNKI and Web of Science databases from January 2000 to November 2021. The risk ingredients involved in TCM-induced reproductive toxicity were divided into glycosides, alkaloids, phenols, terpenoids, anthraquinones, lactones, plant toxin proteins, animal toxins and so forth. Potential mechanisms underlying TCM-induced reproductive toxicity, including steroidogenic toxicity, lipids metabolism abnormity, energy insufficiency, oxidative stress and apoptosis, were illustrated. We also outlined possible biomarkers, especially biomarkers of effect involved in TCM-induced reproductive toxicity, including anti-oxidant enzymes, signalling pathways, genes and growth factors.
