Penis, Testicles, secondary sexual characteristics like increased muscle mass and a "manly" shape to bone structure (most notably the bones of the face and upper torso), and some other less general things.
Testosterone is a male hormone and has no influence in the development of breasts (mammary glands), estrogen the female hormone does,
Testosterone
The most prominent hormone involved in secondary sex characteristics for a male is testosterone.
Testosterone in the womb can influence fetal development by affecting the development of male reproductive organs and brain structures. It can also impact behaviors and cognitive abilities later in life.
Testosterone is the primary hormone responsible for producing and stimulating the development of male characteristics such as facial hair growth, deepening of the voice, and muscle development. It is produced mainly in the testes in men and in smaller amounts in the ovaries and adrenal glands in women.
Testosterone
In males, testosterone and androgen are the principal sex hormones responsible for puberty. The hormone that dominates female development is estradiol and estrogen.
The hormone responsible for the descent of the testes into the scrotum during development is called testosterone. It is produced by the testes and plays a crucial role in the development of male reproductive organs.
Testosterone is the primary hormone responsible for the physical development of men. It is responsible for the development of male characteristics such as facial hair, deep voice, muscle mass, and bone density.
Hormones such as testosterone and estrogen drive the development of secondary sex characteristics during puberty. These hormones are responsible for physical changes like breast development and facial hair growth, which differentiate males and females.
The main male sex hormone is testosterone, which is responsible for the development of male reproductive tissues and characteristics such as muscle mass, body hair, and deepening of the voice.
The hormone testosterone is responsible for male sexual development in the embryo. Through a series of complex processes, testosterone influences the development of male reproductive organs and other male characteristics.
