The external genitalia of the male is distinct from those of the female by the end of the ninth week. Prior to that, the genital tubercle in both sexes is a phallus. The urethral groove forms on the ventral surface of the phallus early in development during the differentiation of the external genitalia.
The genital tubercles of an eight-week-old embryo of either sex are identical. They both have a glans area, which will go on to form the clitoral glans (females) or penile glans (males), a urogenital fold and groove, and an anal tubercle. At around ten weeks, the external genitalia are still similar.
Development of external genitals showing homologues from indifferent to both sexes - male on left. When the fetus is exposed to testosterone, the genital tubercle elongates (primordial phallus) and develops into the glans and shaft of the penis and the urogenital folds fuse to become the penile raphe.

The body of the penis is suspended from the pubic symphysis. [7] It has two surfaces; the dorsal and the ventral or urethral.The penile raphe runs on its ventral surface.. The body is surrounded by a bi-layered model of tunica albuginea in which a distal ligament buttresses the glans penis and plays an integral role to the penile fibroskeleton, and the structure is called "os analog", a term ...
Despite the differences between them, the adult male and female are determined in early development in the 6th week. The gonads and external genitals are derived from the intermediate mesoderm. [7] The three main fetal precursors of the reproductive organs are the Wolffian duct, the Müllerian ducts, and the gonads.
The outer parts are known as the genitals or external genitalia, visible at birth in both sexes, [1] [pages needed] while the inner parts are referred to as internal genitalia, which in both sexes, are always hidden. [2] In plants, male reproductive structures include stamens in flowering plants, which produce pollen. [3]
