Girls Experience Changes in Fat Distribution
When it comes to weight gain, girls undergo certain changes in their bodies, but not in every area. The majority of their weight gain tends to occur in specific regions such as the lower abdomen, rear, thighs, and arms. Additionally, breast growth also contributes to an increase in overall weight. On the other hand, girls may also experience weight loss, particularly in areas where the body deems fat storage unnecessary. Biologically, this weight gain is a preparation for menstruation and childbearing, with the extra weight serving as a protective measure for reproductive organs. Alongside these changes, puberty often brings about a rounding of the hips and bottom, as well as growth spurts for many girls.
Boys Experience a Surge in Testosterone Levels
During puberty, boys undergo significant physical changes driven by hormonal fluctuations. One of the key hormones responsible for these changes is testosterone. As boys enter adolescence, their bodies start producing higher levels of testosterone, which plays a crucial role in the development of sperm and enhances their sex drive. Testosterone levels reach their peak in men during their 20s but gradually decline as they get older. Additionally, during puberty, boys also start producing androgen-binding protein (APB).
