In a hermaphrodite frog, (http://www.nytimes.com/2002/11/19/science/life/19FROG.html) do the sperm from the 'male' fertilize the eggs from the 'male' or does it not produce sperm (this is so confusing)?

Gnomon

I can't see that web site in your question. In most hermaphrodite species, such as snails, individuals are neither male nor female but have characteristics of both, being able to produce both sperm and eggs. Normally such species don't mate with {themselves;} they mate with others to get the benefits of combining characteristics from two parents. The hermaphrodite frogs appear to be an anomaly caused by humans interfering with the environment. They are not necessarily capable of living as hermaphrodites in the long term. Nov 28 02, 8:31 AM

Most hermaphrodite frogs are caused by the use of herbicides that are now banned in certain parts of the world. There are species that can actually change sex naturall due to environmental conditions which would suggest that the unnatural change caused by the chemicals are not that amazing. Jurassic Park used this fact when they used frog DNA to complete the missing DNA of the dinosaurs which resulted in some of the original all female population becoming male and therefore able to reproduce.
