Orgasms
gregladen | January 3, 2010In a recent study, 56 percent of the women interviewed in a sample of 1800 claimed that they had a "g-spot" which is an area inside the vagina with increased sensitivity with respect to sexual arousal.
(Added: See THIS write up of the original research)
But a twin study showed that when one twin claimed whether or not to have a g-spot, the other twin did not make the same claim at the frequency one would expect if the g-spot was the expression of a genetic trait with straight forward Mendelian inheritance.
Therefore, the scientists conclude, the g-spot does not exist. At all.
How can this…

gregladen | May 12, 2009According to a study just coming out in the Journal of Sexual Medicine, "variations in emotional intelligence--the ability to identify and manage emotions of one's self and others--are associated with orgasmic frequency during intercourse and masturbation."
In short, the study found:
Emotional intelligence was not associated with ... age and years of education, nor did we find a significant association between emotional intelligence and potential risk factors for [female orgasmic disorder] FOD such as age, body mass index, physical or sexual abuse, or menopause. We found emotional…
gregladen | January 13, 2008Cells do things (or stop doing things) because of internal homeostatic (or other) regulatory mechanisms, or because of communication with the "outside" via receptor sites located on the cell membrane. To get cells to do what we want (produce more or less of a hormone, for instance, or simply to die as in the case of cancer cells) it would be nice to have a machine that you point at a patient, program a few dials and buttons, and then affect the receptor sites in that person's cells.
Well, the production model isn't quite ready yet, but such a device now exists on both the drawing board and…
