Clinical InformationClinical

  • Spermatic Cord

    either of a pair of tubular structures formed by ductus deferens; arteries; veins; lymphatic vessels; and nerves. the spermatic cord extends from the deep inguinal ring through the inguinal canal to the testis in the scrotum.

  • Spermatic Cord Torsion

    the twisting of the spermatic cord due to an anatomical abnormality that left the testis mobile and dangling in the scrotum. the initial effect of testicular torsion is obstruction of venous return. depending on the duration and degree of cord rotation, testicular symptoms range from edema to interrupted arterial flow and testicular pain. if blood flow to testis is absent for 4 to 6 h, spermatogenesis may be permanently lost.

  • Sterilization Reversal

    procedures to reverse the effect of reproductive sterilization and to regain fertility. reversal procedures include those used to restore the flow in the fallopian tube or the vas deferens.

  • Vas Deferens

    the excretory duct of the testes that carries spermatozoa. it rises from the scrotum and joins the seminal vesicles to form the ejaculatory duct.

Patient EducationClinical

Testicular Cancer

Testicular cancer is a cancer that develops in the tissues of one or both testicles. The testicles, or testes, are part of the male reproductive system. They make male hormones and sperm. They are two egg-shaped glands inside the scrotum, a sac of loose skin that lies below the penis. You can get cancer in one or both testicles.
