In most terrestrial mammals, the scrotum (pl.: scrotums or scrota; possibly from Latin scortum, meaning "hide" or "skin") [1] [2] or scrotal sac is a part of the external male genitalia located at the base of the penis. It consists of a sac of skin containing the external spermatic fascia, testicles, epididymides, and vasa deferentia. The ...
The cremaster muscle's function is to raise and lower the testes in order to regulate scrotal temperature for optimal spermatogenesis and survival of the resultant spermatozoa. The ideal temperature for human sperm development is around 34 degrees Celsius, which is about 4 degrees Celsius below body temperature. [3]
Epididymitis is a medical condition characterized by inflammation of the epididymis, a curved structure at the back of the testicle. [1] Onset of pain is typically over a day or two. [1] The pain may improve with raising the testicle. [1] Other symptoms may include swelling of the testicle, burning with urination, or frequent urination. [1]
The presence of the cremasteric reflex does not eliminate testicular torsion from a differential diagnosis, but it does broaden the possibilities to include epididymitis or other causes of scrotal and testicular pain. In any event, if testicular torsion cannot be definitively eliminated in an expeditious manner, a testicular Doppler ultrasound ...
The genital branch of the genitofemoral nerve, also known as the external spermatic nerve in males, is a nerve in the abdomen that arises from the genitofemoral nerve.The genital branch supplies the cremaster muscle and anterior scrotal skin in males, and the skin of the mons pubis and labia majora in females.
The testicles are very sensitive to impact and injury. The pain involved travels up from each testicle into the abdominal cavity, via the spermatic plexus, which is the primary nerve of each testicle. [31] This will cause pain in the hip and the back. The pain usually fades within a few minutes. Testicular torsion is a medical emergency. This ...
Testicular torsion may result in irreversible damage to the testicle within hours. A collection of serous fluid in the spermatic cord is named 'funiculocele'. The contents of the abdominal cavity may protrude into the inguinal canal, producing an indirect inguinal hernia. Varicose veins of the spermatic cord are referred to as varicocele ...
The dartos fascia, dartos tunic or simply dartos is a layer of connective tissue found in the penile shaft, foreskin and scrotum. [1] The penile portion is referred to as the superficial fascia of penis or the subcutaneous tissue of penis, [2] while the scrotal part is the dartos proper.
