这些早期的变化让我们了解为什么睾酮被认为是一种男性激素，因为睾丸负责产生睾酮和精子，激素如促黄体生成素(LH)和卵泡刺激素(FSH)是由垂体前叶(i。这些激素在刺激睾丸激素和精子成熟方面起作用;女性也有这些激素，但它们会导致卵巢分泌雌激素。此外,Y染色体在发展中发挥至关重要的作用,它允许睾酮穿过血脑屏障将潜在的女性大脑转化为musicalised,因此,允许男性产生大约十倍睾丸激素睾丸激素水平较高的男性比女性。结果,挑战一个人在一个男性化的外表。进化心理学认为，就等级统治而言，人类男性与动物没有什么不同。这意味着男人愿意为更高等级与其他男人竞争来获得交配机会,因为不像女人,男人被认为是容易更换,因此,获得注意力从雌性,雄性必须使用他们的规模和实力获得交配机会击败其他雄性(Vandello和彼此,2013),因此,通过增加他们的亲属的生存繁殖,通过他们的健康,更强的特征上的后代(巴斯2007;2000年)。此外，男性的精子是充足的，如果选择了许多伴侣，它们可以快速繁殖——另一方面，女性在性行为上投入了大量的时间和精力，这使得她们对自己选择的伴侣非常挑剔。

These early changes allows an understanding why testosterone is thought as a male hormone, as the testes are responsible for producing testosterone and sperm, hormones such as luteinizing hormone (LH) and follicle-stimulating hormone (FSH) that are secreted by the anterior pituitary gland (i.e located in the brain), and these hormones play a role in the stimulation of testosterone and sperm maturation; female’s also have these hormones, but they cause a secretion of estrogens in the ovaries . Furthermore, Y chromosome plays a crucial role in development, it allows testosterone to cross the blood-brain barrier to convert the would-be feminine brain into a musicalised one , thus, allowing males to produce roughly ten times as much testosterone than females .A consequence of higher testosterone levels in men, challenges a man in keeping up a masculine appearance. Evolutionary psychology argue that human males are no different from animals in terms of hierarchy’s dominance. This means that men are willing to compete against other men for a higher rank to gain mating opportunities, because unlike womanhood, manhood is seen to be easily replaced, therefore, to gain attention from females, males must use their size and strength to gain mating opportunities in defeating other males (Vandello and Bosson, 2013a), thus, through reproducing it increases the survival of their kin, by passing their fitter, stronger traits onto offspring’s (Buss 2007; Gangestad and Simpson 2000). In addition, men’s sperm is plentiful and can reproduce at a fast rate with many partners if chosen – females on the other hand invest a great deal of time and energy in their sexual encounter which makes them very selective of whom they chose to mate with.
