Berberine alters the gut microbiota metabolism and impairs spermatogenesis.

ABSTRACT: Berberine (BBR) is used to treat diarrhea clinically. However, its reproductive toxicity is unclear. This study aims to investigate the impact of BBR on the male reproductive system. Intragastric BBR administration for 14 consecutive days results in a significant decrease in the serum testosterone concentration, epididymal sperm concentration, mating rate and fecundity of male mice. Testicular treatment with testosterone propionate (TP) partially reverses the damage caused by BBR to the male reproductive system. Mechanistically, the decrease in Muribaculaceae abundance in the gut microbiota of mice is the principal cause of the BBR-induced decrease in the sperm concentration. Both fecal microbiota transplantation (FMT) and polyethylene glycol (PEG) treatment demonstrate that Muribaculaceae
