Paraphrase and summary In 1935, testosterone was first extracted from testicles of mice by a Dutch scientistand subsequently synthesized by a Germany by the name Adolf Butenandt. Both men and women in testicles and ovaries and glands respectively (Morgenentaler, 39) produce testosterone. Women may change their sex through injection with this testosterone to enable them develop male characteristics such as a deep voice. This is because the male body is able to convert the testosterone into estradiol that is a female hormone.

Additionally, female body posses receptors for testosterone. Therefore men are differentiated from women biologically because they produce testosterone in larger quantities than women. The effects of testosterone begin in early stages of development, where an embryo is usually a female unless its hormones are altered. Therefore, a testosterone is normally used to effect this change into a boy, and normally men experience two periods of testosterone flood. This is during conception at six weeks and at teens.

At six weeks, the testosterone functions to masculinize mind and body and complete the process at puberty. This hormone is, therefore, very important, for in its absence humans would always go back to the female sex which is the default sex of mankind (Morgenentaler, 39) This implies that the effect of testosterone is systemic. This is evident in genital distinction and its role in development of some characteristics such as deep voice, muscle and strength of upper body that women do not have.

It also brings about behavioral differences. However, this is only based on research, for it is unethical to conduct such studies on man. However, it has been proved that in certain species where females are aggressive as compared to their males, it is because of females having more testosterone than males (Morgenentaler, 39).A good example is in the female hyenas. This means that levels of testosterone influence any behavior characteristic of man, and either males or females may exhibit this.
