This particular episode of All in the Mind focuses on the hypothesis “Is being gay in your biology?” The research of three scientists focusing on what biological traits are different between gay people and straight people is presented in an easy to understand fashion.
The first researcher we come across is Psychologist Dr. Richard A. Lippa. Dr. Lippa is looking for a link between gay people and their personalities by trying to figure out if genes play a role in the interests of gay people. One of the things Dr. Lippa looks for during his field research is if the swirl of a man’s hair is counter-clockwise or clockwise while interviewing the subject. He also pays particular attention to other phenotypical aspects of his research subjects such

Sven Bocklandt of UCLA who is researching the genetics of sexual orientation. He is trying to figure out what exactly is different in gay peoples genes as opposed to a straight persons. As Dr. Lippa’s research showed earlier, there are characteristic phenotypic traits in gay people, but that means there is a gene coding for that as well. Dr. Bocklandt discussed some regions where the gay gene may be found. He also elaborated on his research to use gay twins to find the difference between the two sexualities and what has already found. Dr. Bocklandt says the X chromosome is particularly interesting when it comes to identifying the genetic difference between gay and straight …show more content…
LeVay’s theories study about the hypothalamus and the theory of pre-natal hormones also caught my attention. In men, testosterone is the main hormone that regulates the sexual desire and many treatments such as testosterone replacement therapy try to market themselves as a way to increase libido. The study in laboratory animals caught my attention because pre-natal hormone levels influenced final sexual orientation. So, I think this pre-natal hormone levels have a direct effect on the INAH 3. Since the hypothalamus produces Gonadotropin Releasing Hormone (GnRH) and this is a precursor to testosterone, I believe feedback simulation by the testosterone increases the size of INAH 3 found in the hypothalamus. More studies could be potentiated on this research to see if other aspects line up with this research such as testosterone levels among gay and straight men and among lesbian and straight women. The most interesting part of all of this research is that it could someday allow a physician to use the phenotypic detail of a patient to recognize health hazards they may have without using many of the expensive or invasive techniques available
