Statement A is true but B is false.
Testosterone is the primary male sex hormone produced by the testes, which is responsible for bringing about secondary sexual changes and changes in physical appearance seen in boys at the time of puberty, such as deepening of the voice, facial hair growth, and broad shoulders. Progesterone, on the other hand, is primarily a female sex hormone produced by the ovaries, which regulates the menstrual cycle and pregnancy, making Statement B false.

Just as a software update installs specific feature packages designed for distinct user profiles, the endocrine system releases gender-specific master hormones (testosterone for males, estrogen and progesterone for females) to trigger distinct developmental changes during adolescence.

Hypothalamus\rightarrow Pituitary┬а(LH/FSH)\rightarrow Ovaries\rightarrow Estrogen┬а&┬аProgesterone
During puberty, the hypothalamus signals the pituitary gland to release gonadotropins (LH and FSH). In males, Luteinizing Hormone (LH) stimulates the Leydig cells in the testes to secrete testosterone, which triggers anabolic changes, skeletal growth, spermatogenesis, and the development of secondary sexual characteristics.
Testosterone is secreted by the testes in males and controls secondary sexual characteristics.
Progesterone is a female sex hormone secreted primarily by the corpus luteum in ovaries.
Secondary sexual characters in boys include facial hair, voice deepening, and muscular growth.
Secondary sexual characters in girls include breast development and widening of hips.
Clear distinction between male and female endocrine regulators during adolescence.

| Feature | Testosterone | Progesterone |
|---|---|---|
Primary Source | Testes (Leydig cells) | Ovaries (Corpus luteum) |
Target Audience | Males (Boys) | Females (Girls) |
Estrogen is the primary hormone responsible for secondary sexual characteristics in girls, whereas progesterone prepares the uterus for pregnancy.
Option D is correct because Statement A correctly identifies testosterone as the male puberty hormone, while Statement B incorrectly assigns progesterone as the hormone for boys.
