In recent years, the impact of productive harmful factors on reproductive function has drawn more and more attention, and its research work is also deepening. This article gives an overview of the research progress of this work. 1 chemical factors 1.1 Lead lead can lead to male sperm generation inhibited or abnormal increase in the number of sperm, thereby interfering with early embryonic development and reduce the pregnancy rate of female rats. Lead on the implantation process of fertilized eggs also inhibit the role of different views. Wide believes that may be related to the inhibition of blast cell development and adhesion.
