Just to address the statements of lotsocats and the issue you just brought up, Brandon, my question is - are catholic priests less "male" because they are celibate their entire lives?
I think the point of this discussion is to make it a bit clearer that "male" and "female" are socially learned roles and it is we that place value judgments on them. Personally, I think just because a person doesn't have sex doesn't mean they're less male or female.
But, to address studies. I will have more as I'm in the process of collecting them for you. Unfortunately, it appears that much of what you're interested in is not available on line, so I'll only be able to provide the citations, and you'll have to head to your local library or college library to find the materials themselves.
Here is a study by the Winn-Feline foundation, a non-profit organization established by the Cat Fancier's Association, Inc. to support health-related studies benefiting cats.http://www.winnfelinehealth.org/repo...ly-neuter.html
If you want to read the full report and not just the study, this is the reference for it:

Funded by the Winn Feline Foundation, February 1991. Continuation funded February 1992. A progress report on a study funded by The Winn Feline Foundation (Summary prepared by Diana Cruden, Ph.D. 1995/1996)
Here are links to a study on the difference between gender and sex. Although this addresses humans, it does address the higher-brain function required to make the distinction between the biology of the "sex" of a being and the process of gender-identity of a being.http://canfield.etext.net/Chapter5.htm
Here is an article by a well-published researcher, Sarah Hartwell. A section of this article addresses the question of whether or not neutering is merely an attempt to "denature" cats:http://www.messybeast.com/antineuter.htm
Unfortunately, the Journal of the American Veterinary Medical Association (JAVMA) is not availble online to non-subscribers, but it is one of the most respected in the field of animal medical issues. Appropriate publication:
