Everyone has hormones, not just girls. All a hormone is is a chemical released by cells in the body, and there something like 40 or 50 hormones in the bodies of both genders. If you want to know why girls have certain hormones (especially ones classified as estrogen), then the answer still is even males have estrogen, just as females have testosterone. Females, however, have much more estrogen than males, and that is because it is necessary to regulate their menstrual cycle and in the formation of breasts. These high levels of estrogen are also what makes women sometime moodier than males, and is also responsible for many other characteristics of females, but it is also vital to the health of both males and females.

Freemartinism is when a heifer has male sex characteristics but has underdeveloped female sex organs. It is caused by sharing a placenta with a twin bull calf. The male sex hormones that is emitted by the male fetus as he develops in the womb inhibits the female's sex hormones, and consequently prohibits her from developing normal female reproductive organs. She retains the testosterone and develops bull-like characteristics after birth and as she gets older. Freemartins are sterile, so they're better off being raised for the freezer.
