At six weeks post-conception, the differentiation of the external genitalia in the male and female has not taken place. At eight weeks, a distinct phallus is present during the indifferent stage. By the 10th-12th week, the genitalia are distinctly male or female being and derived from their homologous structures. At 16 weeks post-conception ...
Its fibres are then distributed to the skin of the upper and medial part of the thigh, and to the following locations in the male and female: In the male ("anterior scrotal nerve"): to the skin over the root of the penis and upper part of the scrotum.

The inguinal ligament attaches to it. [1] Part of the abdominal external oblique muscle inserts onto it. [1] The inferior epigastric artery passes between the pubic tubercle and the anterior superior iliac spine. [2] The pubic spine is a rough ridge that extends from the pubic tubercle to the upper border of the pubic symphysis.
This cavity is a short, curved canal, deeper on its posterior than on its anterior wall. [1] Some sources consider this region to be the entirety of the pelvic cavity. Other sources define the pelvic cavity as the larger space including the greater pelvis , just above the pelvic inlet.
Left and right inguinal regions shown in lower part of diagram. In human anatomy, the groin, also known as the inguinal region or iliac region, [1] is the junctional area between the torso and the thigh. [2] The groin is at the front of the body on either side of the pubic tubercle, where the lower part of the abdominal wall meets the thigh.
The pampiniform plexus (from Latin pampinus 'tendril' and forma 'form') is a venous plexus – a network of many small veins found in the human male spermatic cord, and the suspensory ligament of the ovary. In the male, it is formed by the union of multiple testicular veins from the back of the testis and tributaries from the epididymis.
