Sinossi
Cosa fa sì che un bambino o una bambina cresca omosessuale o eterosessuale? Simon LeVay indaga l'orientamento sessuale da una prospettiva biologica e lo considera il risultato dell'interazione tra geni, ormoni sessuali e processi di sviluppo a livello cerebrale e somatico. In un famoso lavoro pubblicato su Science nel 1991, LeVay aveva identificato una differenza nella struttura dell'ipotalamo di uomini gay ed eterosessuali: da allora un numero crescente di ricercatori si è dedicato allo studio delle radici biologiche dell'orientamento sessuale. In questo libro LeVay spiega in modo accessibile a tutti i risultati finora raggiunti dalla ricerca, conducendo il lettore in un viaggio affascinante nei laboratori di genetica, endocrinologia, neuroscienze, psicologia cognitiva e psicologia evoluzionistica. La conclusione generale è chiara: differenze genetiche, variabilità dei processi biologici ed effetti del feedback ambientale interagiscono in maniera complessa nei diversi individui determinando l'orientamento sessuale e le sue sfumature.

Recensioni
This is really a 3.5 star review. LeVay's honest approach and commitment to thoroughly explaining the research makes this the most enlightening read on the "biology did most of it" side of the current debate around gender and sexual identity. I thoroughly enjoyed this book, and would unhesitatingly
This book puts forward a lot of solid scientific studies and manages to do so with fairly little bias, pointing out the potential failings of many its cited studies. it has done its research well (a good 1/4th of the book is bibliography. I can respect that XD). However, while I must give the book cr Leggi tutto
An interesting read, this book is written by a neuroscientist. LeVay refers to a lot of researches done in homosexuality and tries to do it on a unbiased way. I find the book informative but at some point similar data were repeated and with different results so it was a little bit confusing. Overall Leggi tutto
I conceptualize Human behavior as emerging from a confluence of biological, psychological and social factors. As for the (tiered AF) nature v nurture debate. I assume that nature (innate traits) writes the rough draft, and nurture (social and environmental factors) finishes the final edit. Nature an Leggi tutto
"Gay, Straight and the Reason Why: The Science of Sexual Orientation" mainly uses biology and psychology to deal with homosexuality. The author puts forward many researches conducted by various scientists for years and discusses each of them in this eleven-chapter book. Not being knowledgeable enoug Leggi tutto
LeVay presented varied and routinely underdeveloped areas of research methodically, objectively, and honestly, however, some of the research that he presented was, in my opinion, so shaky and devoid of anything significant or conclusive that I felt like he would have been best to omit it all togethe Leggi tutto
This was an interesting read. Written by a scientist, and...it sounds like it. Not that it was especially technical, just lacked any authorial melodrama. He had a lot of sentences containing "but I'll talk about that in subsequent chapters," which I found a bit irritating. I also doubt this book wil Leggi tutto
This book is a great summary of all the scientific research that has been done on sexual orientation. LeVay discusses both his research and the research of others, as well as commenting on whether each study is reliable or not. He's very upfront and honest about what studies produced valid findings.
