[1] While varicocele is the diagnostic term for swelling in the valveless venous distribution of the male pampiniform plexus, this embryological structure, common to males and females, is often incidentally noted to be swollen during laproscopic examinations in both symptomatic and asymptomatic females. [2]
[1] cremasteric muscle and fascia, formed from a continuation of the internal oblique muscle and its fascia. [1] internal spermatic fascia, continuous with the transversalis fascia. [1] The normal diameter of the spermatic cord is about 16 mm (range 11 to 22 mm). [2] It is located behind the tunica vaginalis. [3]
A varicocele is, in a man, an abnormal enlargement of the pampiniform venous plexus in the scrotum; in a woman, it is an abnormal painful swelling to the embryologically identical pampiniform venous plexus; it is more commonly called pelvic compression syndrome. In the male varicocele, this plexus of veins drains blood from the testicles back ...
While one may expect the female to have an equal prevalence of pelvic compression syndrome due to the identical embryological origin of the valveless pampiniform plexus, this condition is thought to be underdiagnosed due to the broad differential of the pain pattern: unilateral or bilateral pain, dull to sharp, constant to intermittent pain worsening with any increase in abdominal pressure.
Valveless testicular veins are a major contributing factor to varicocele. [1] Since the left testicular vein goes all the way up to the left renal vein before it empties, this results in a higher tendency for the left testicle to develop varicocele because of the gravity working on the column of blood in this vein, compared to the right internal spermatic vein.
They differ in size according to their position, those in the middle of the gland being larger and longer. The lobules are conical in shape, the base being directed toward the circumference of the organ, the apex toward the mediastinum testis.
An average adult testicle measures up to 5 cm × 2 cm × 3 cm (2 in × 3 ⁄ 4 in × 1 + 1 ⁄ 4 in). The Tanner scale , which is used to assess the maturity of the male genitalia, assigns a maturity stage to the calculated volume ranging from stage I, a volume of less than 1.5 cm 3 ; to stage V, a volume greater than 20 cm 3 .
