What is correct about the development of internal genitalia in a male embryo?
Understand the Problem
The question is asking which statements about the development of internal genitalia in a male embryo are correct. It presents various options regarding anatomical developments and potential anomalies linked to these processes, and the user needs to evaluate the truth of these statements.
Answer
Androgens cause phallus elongation and Wolffian ducts form male internal genitalia.
Androgens secreted by the testes lead to the elongation of the phallus into the penis and the fusion of the urogenital folds to form the spongy urethra. The Wolffian ducts develop into internal structures such as the epididymis and vas deferens.

More Information
In male embryos, androgens play a crucial role in differentiating the genital structures. The Wolffian ducts develop into key components of the male reproductive tract, while the phallus elongation is integral to forming the external male genitalia.
Tips
A common mistake is confusing the development timelines of external and internal genitalia or mixing their triggers, like hormones and genetic factors.
