  • Title: [Overview of reproductive toxicity studies on Tripterygium wilfordii in recent 40 years].
    Author: Xu Y, Fan YF, Zhao Y, Lin N.

    Abstract:
    This paper summarizes the research progress of reproductive toxicity of Tripterygium wilfordii from 1979,and the toxicity characterization,damage mechanism,and attenuated measures are summarized. It was found that,the reproductive toxicity caused by T. wilfordii is mainly distributed on components of Tripterygium glycosides,triptolide,tripchlorolide,and clinically preparations,such as Leigongteng Tablets and Tripterygium Glycosides Tablets. Adverse reactions to male reproductive system caused by Tripterygium preparations mainly include decreased sperm motility,oligospermia or spermatozoa,decreased fertility or infertility,etc. Long-term drug use may also lead to testicular atrophy and decreased sexual desire. Adverse reactions to women are mainly manifested as menstrual disorders,decreased menstrual volume or even amenorrhea,decreased sexual desire,infertility,etc. The reproductive toxicity of T. wilfordii is related to apoptosis of reproductive cells,disturbance of spermatogenesis or oogenesis,damage of testis and ovary in reproductive target tissues,and changes of internal environment in gonad tissues( hormones,hormone synthesis rate-limiting enzymes and energy metabolism). Drug compatibility,hormone replacement,medication duration and dosage form changes can help reduce the damage of T. wilfordii to the reproductive system. In addition,in view of the existing problems in the current study,the author proposes new directions in clinical studies,pharmacological metabolism mechanism,preparation quality standards and new therapeutic effects,etc.,to provide a basis for the safe and reasonable clinical application of T. wilfordii.
