Verified step by step guidance

Step 1: Understand the concept of secondary sexual characteristics. These are traits that develop during puberty and are not directly involved in reproduction, such as facial hair, deepening of the voice, and increased muscle mass in males.

Step 2: Review the role of hormones in the body. Hormones are chemical messengers that regulate various physiological processes, including growth, metabolism, and sexual development.

Step 3: Examine the function of each hormone listed in the problem: - Estrogen: Primarily responsible for the development of female secondary sexual characteristics. - Prolactin: Involved in milk production and other functions, but not related to male secondary sexual characteristics. - Insulin: Regulates blood sugar levels and metabolism, not related to sexual characteristics. - Testosterone: The primary male sex hormone responsible for inducing the development of male secondary sexual characteristics.

Step 4: Identify the correct hormone based on its function. Testosterone is the hormone that induces the development of male secondary sexual characteristics, such as facial hair, deep voice, and increased muscle mass.

Step 5: Conclude that understanding the specific roles of hormones is essential for identifying their effects on the body, particularly in processes like sexual development.
