Intrauterine/newborn testicular torsion
Abstract:
Although spermatic cord torsion in the neonate is uncommon, early recognition with prompt surgical exploration and detorsion of the cord can result in preservation of some testicular tissue. Palpation of the infantile testes can be difficult, and distinguishing testicular from extratesticular abnormalities may not be possible. High-resolution real-time ultrasonography is an effective, noninvasive method of differentiating between the two. If sonography demonstrates and abnormal testicle, prompt surgical exploration is indicated.

01:19Testes: Gross Anatomy
The testes, also known as testicles, are the male gonads. They are housed within the scrotum, a sac-like structure located beneath the penis. The scrotum's primary role is to regulate the temperature of the testes, which is crucial for sperm production.
Each testis is surrounded by the tunica albuginea, a dense connective tissue layer that provides structural support and protection. This layer is covered by an outer serous membrane called the tunica vaginalis, which helps reduce friction...

01:27Testes: Histology
A tough, fibrous membrane, the tunica albuginea, covers the testes, extending inward to form fibrous partitions or septa, dividing them into internal compartments called lobules. Each lobule has 1 to 3 tightly coiled seminiferous tubules where sperm production occurs. These tubules merge into a tubular network at the back of the testis, known as the rete testis. It connects to 15 to 20 efferent ductules, leading to the epididymis.
