During fetal development, testosterone influences the formation of male reproductive organs, including the differentiation of the testes and the development of the penis and scrotum. Testosterone regulation involves a delicate feedback loop, wherein elevated testosterone levels inhibit further release of GnRH and LH, maintaining hormonal balance.
