Answer :
In addition to gender, the three main factors that affect the timing of puberty are:
1. Genes: Genetic factors play a significant role in determining when puberty begins. Individuals inherit genes from their parents that influence the timing of puberty, as well as other aspects of growth and development.
2. Body fat or nutrition: Adequate nutrition and body fat are important for the onset of puberty. The body needs a certain amount of fat to support the hormonal changes that occur during this period. Factors such as diet and overall health can impact the timing of puberty.
3. Stress: Emotional and physical stress can also affect the timing of puberty. High levels of stress, whether due to environmental factors, personal experiences, or other reasons, can disrupt the hormonal balance necessary for puberty to start at the expected time.
These three factors interact with each other and with the individual's overall health and environment to determine the onset of puberty. It's essential to consider these factors holistically when understanding the timing of puberty in different individuals.
