The invention discloses an
intestinal bacterium for improving
semen quality and application thereof, and belongs to the field of microbial technology and biological
medicine. In order to solve the problem that in the prior art, specific probiotics are not used for improving male reproductive injury induced by
high fat diet, the invention provides a method for applying the allobacter faecalis strain (A.s) or an inactivated form (P-A.s) of the allobacter faecalis strain (A.s) to the male reproductive injury. Animal experiments show that compared with a
high fat diet model group, supplementation of A.s or P-A.s can significantly inhibit abnormal
weight growth, improve testis index, improve
sperm density,
vitality, movement speed and testicular
testosterone level, and can effectively
repair tissue form damage of testis and
epididymis and abnormal
sperm ultrastructure. Wherein the improvement effect of the inactivated bacterium form P-A.s is particularly prominent.
