Deciphering the interactions between gut microbiota and male fertility

Summary :

The number of infertile couples has been increasing steadily since the 80s, with 1 in 6 couples infertile worldwide currently. In 50% of these cases, the causes can be traced to men. However, the causes remain unknown in ~4 out of 10 infertile men.

The scarce evidence suggests that gut microbiota dysbiosis may impact male fertility. In this talk, Professor O’Flaherty will discuss current knowledge on the relationships between gut microbiota dysbiosis and male infertility and the challenges and future perspectives in reproductive medicine research.
