You really can't compare the two, however if you are on clomid, you should not be taking ovulex.
Clomid triggers ovulation
ovulex supposedly helps create a health environment for conception, though i'm not sure of any studies out there that actually back that claim up.
Clomid should only be taken while you are under the care of a physcian.
Ovulex is over the counter. Supplements such as these need to be taken for several months so that the body will build up on it's nutrients.
Sorry I couldn't be of more help!
