In development of male fetus following statements are true except
**Core Concept**
During fetal development, the formation of the male reproductive system involves the presence of specific genes and hormones that regulate the development of testes, Wolffian ducts, and external genitalia. The presence or absence of these factors determines the sex of the fetus.
**Why the Correct Answer is Right**
The development of a male fetus is dependent on the presence of the SRY gene on the Y chromosome, which triggers the development of testes. The testes then produce anti-Müllerian hormone (AMH), which causes the regression of the Müllerian ducts, and testosterone, which promotes the development of the Wolffian ducts and external genitalia. The presence of testosterone also leads to the formation of the prostate gland and seminal vesicles.

**Clinical Pearl / High-Yield Fact**
The SRY gene is a critical factor in determining the sex of the fetus. Its absence or mutation leads to the development of a female fetus. A key clinical correlation is that individuals with androgen insensitivity syndrome (AIS) have a 46,XY karyotype but develop as females due to the inability to respond to androgens.
