Men who are obese tend to have lower testosterone levels. New work in mice (not necessarily the same as men) suggests that a high fat diet producing obesity causes:

- Sperm DNA damage was also increased
- The number of sperm bound to each oocyte was significantly lower
- significantly lower fertilization rates
