絕育真係乜都得咩？諗清楚…

近排係唔少group 都見到好多人不斷咁推崇絕育，仲話越早越育越好…

好多都係因為隻狗唔乖﹑有攻擊性﹑亂屙尿等等，就比人問：絕左育未？絕完育會乖好多。

亦有部份都話絕育對狗百利而無一害，有益身心，人狗皆愛惠。之但係，呢類有關健康既推論，一直都係theory based，無實證的。

舊年年頭，其實美國果邊出左份research paper，叫做 The Vizsla Study，就係研究絕育對狗隻行為同埋健康既影響。（絕育，Gonadectomy﹑Desexing﹑Neutering﹑Spaying，即係摘除整個生殖器官，香港主流手術）

結論係，所有野都係同大家既認知係兩回事。大家一直以黎都當絕育係萬能聖藥，以為一剪就可以平亂。所以我就quote 文章裡面比較特別既發現比大家參考。

In the study, spayed and neutered dogs were also more likely to develop behavior disorders than intact dogs. This included fear of storms, separation anxiety, fear of noises, timidity, excitability, aggression, hyperactivity and fear biting. Another study found neutered dogs were more aggressive, fearful, excitable and less trainable than intact dogs. (Parvene Farhoody @ M. Christine Zink, Behavioral and Physical Effects of Spaying and Neutering Domestic Dogs, May 2010)

有興趣睇沈悶既全文，可以睇呢到。

呢個係一個好認真既科學病理統計研究項目，用左十年去觀察2505隻 Vizsla Dogs。絕對唔係街坊師奶同你講：我隻狗絕完育好定咁求其。

至於點解絕完育隻狗會好定唔想郁等等，好可能係 Hypothyroidism 既病徵。

我知道呢到好多人唔想信學術研究既野，我都唔係一個學院派既人。但唔係學院派，唔代表唔可以相信客觀事實。

至於大家點樣interpret個result都好，都值得反思帶自己隻狗狗絕育係為左乜野。控制生育？健康？還是純粹聽人講絕完育會乖？
