Answer :
The statement that testosterone is responsible for many of the changes in the male physique is true. Testosterone is vital for the development of male reproductive tissues and secondary sexual characteristics, and it is essential for spermatogenesis.
True. Testosterone is indeed the male hormone responsible for many of the changes in the male physique. Testosterone, the primary male sex hormone, plays a crucial role in the development of male reproductive tissues, such as the testes and prostate, and promotes secondary sexual characteristics, which include an increased muscle and bone mass, and the growth of body hair.
Apart from these physical changes, testosterone is also essential for spermatogenesis, which is the process of sperm production in the testes.
During adolescence, the increase in testosterone levels leads to several visible changes, commonly referred to as secondary sex characteristics. These include the deepening of the voice, the growth of facial, axillary, and pubic hair, an increase in muscle bulk, and the beginnings of the sex drive. Hence, testosterone is critical not only for physical maturity but also plays a significant role in male sexual health.
