Normally the testes begin its descent through the inguinal canal to the scrotum at 36 weeks’ of gestation and completed at birth. Failure in the course of testes descent will result in undescended testes (Cryptorchidism). Undescended testis is found in 4% of full-term infants but only 0.8% of males at the age of 1 year have true cryptorchidism.
Varicocele might be noticed as soft lumps, usually above the testicle and mostly on the left side of the scrotum. [5] Right-sided and bilateral varicocele does also occur. Men with varicocele can feel symptoms of pain or heaviness in their scrotum. [5] Large varicoceles present as plexus of veins and may be described as a "bag of worms".
The sex of the fetus may be discerned by ultrasound as early as 11 weeks' gestation. The accuracy is relatively imprecise when attempted early. [15] [16] [17] After 13 weeks' gestation, a high accuracy of between 99% and 100% is possible if the fetus does not display intersex external characteristics. [18]
Varicoceles and testicular torsion are conditions in which direct damage to the testicles can potentially lead to testicular atrophy. [6] [7] Varicoceles are pooling of blood in the veins that deliver blood away from the testicles and are relatively common, occurring in approximately 15% of adolescent and adults with testicles. [7]
Diagnosis of female varicocele, properly called pelvic compression syndrome, should be expected to be as frequent as male varicocele (15% of healthy asymptomatic men which are thought to develop primarily during puberty and prevalence increases approximately 10% per decade of life [3]).

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.
Abdominal ultrasound was performed, identifying a normal gallbladder. However, due to the patients age and abnormal vital signs, an echo was performed immediately after the gallbladder ultrasound and identified the following: File:UOTW 36 - Ultrasound of the Week 3.jpg
