During the development of the male reproductive system, the testis-determining factor (TDF) initiates the differentiation of the indifferent gonad into a testis. Which of the following accurately describes the subsequent cascade of events related to testicular descent?
Sertoli cells produce testosterone, stimulating Wolffian duct development, while Leydig cells produce AMH, causing Müllerian duct regression. Testicular descent is independent of hormonal influence.
Leydig cells produce both testosterone and AMH, leading to Wolffian duct development and Müllerian duct regression, respectively. INSL3 inhibits testicular descent until puberty.
Sertoli cells produce AMH, leading to Müllerian duct regression, followed by testosterone production by Leydig cells, promoting Wolffian duct development. INSL3 mediates transabdominal testicular descent, and androgens contribute to the inguinoscrotal phase.
Testosterone production precedes AMH production, and both are secreted by Leydig cells. The gubernaculum pulls the testes into the abdomen, and INSL3 initiates their descent into the scrotum.
