"persistence of part of the processus vaginalis leads to the formation of a hydrocele (of the cord or testis)."
"By the 8th week of development, the testis is attached at its caudal pole to the gubernaculum, a mesenchymal linear band, to the lower abdominal wall in the inguinal region (between the internal and external oblique muscles)."
"As the intra-abdominal phase of descent starts, the gubernaculum grows inferiorly towards the scrotal swellings, pulling the testis down with it. At the same time, and completely independently, an elongated diverticulum of peritoneum from the anterior lower abdominal cavity develops, the processus vaginalis. This invaginates through the abdominal wall and together with the gubernaculum-driven testicular descent, forms the spermatic cord along with the inguinal canal, deep and superficial inguinal rings."
"obliteration of the left processus vaginalis (PPV) occurs first"
"failure of obliteration of the PPV is more common on the right and predisposes to:"
"indirect inguinal hernia (which occupies the PPV)"
