Orgasm men are capable of achieving them is supported by men who have reported having multiple, consecutive orgasms, particularly without ejaculation. Males who experience dry orgasms can often produce multiple orgasms, as the refractory period is reduced. An increased infusion of the hormone oxytocin during ejaculation is believed to be chiefly responsible for the refractory period, and the amount by which oxytocin is increased may affect the length of each refractory period. Another chemical which is considered to be responsible for the male refractory period is prolactin, which represses dopamine, which is responsible for sexual arousal. Because of this, there is
Organic milk There is no evidence that conventional milk contains significantly increased amounts of bovine growth hormone. Any bovine GH that might remain in conventional milk is not biologically active in humans because of structural differences and susceptibility to digestion in the stomach." One review noted that some consumers like the taste of organic milk, while others do not, and suggested that the amount of heat treatment is likely to be a significant factor in determining the taste of the milk. Certain treatments, such as ultra-heat treatments used by milk producers, can impart a slight nutty taste to the milk. Overall, the
