I'm not exactly sure that there is a "cure" per say. While the neurological results show an interesting co-relation between the makeup of the brain between gay men and straight women, the more interesting part remains that in previous articles similar to this that I've read, it was also noted that during the pregnancy, the amount of hormones that the fetus is exposed to proportionately tended to influence the sexual orientation of the resulting child. This was based on certain levels, particularly estrogen in which the fetus was exposed to during the pregnancy and if I'm not mistaken, the level of testosterone that the sperm is subjected to prior to insemination, compared to the gender of the fetus.
As I recall, it was noted that for a male fetus where the sperm was subjected to a lower level of testosterone, and the fetus during pregnancy was somehow exposed to a higher level of estrogen, that the result was a gay male. By the same token, a female sperm exposed to higher levels of testosterone and exposed to a more elevated level of estrogen generally resulted in a lesbian. All of that being said, it just further emphasizes that sexual orientation is predetermined prior to the birthing process, and not a matter of a "choice".
This just adds to the more interesting plethora of information that one can find on the subject, which further suggests that it is not a matter of choice, rather a matter of genetics and body chemistry. As for the "cure", I fail to see how such a thing would be effective in any way whatsoever, especially seeing as how there is further scientific evidence that reasonably suggests that it is not a matter of choice.
