| left superior intercostal vein | <anatomy, vein> The vein formed by the union of the left second, third, and fourth intercostal veins; it passes forward across the arch of the aorta to empty into the left brachiocephalic vein and frequently communicates also with the accessory hemiazygos vein.

Synonym: vena umbilicalis sinistra. (05 Mar 2000) |
| acute testicular pain | <radiology> Diagnostic considerations: Testicular torsion, Torsion of testicular appendix, Epididymo-orchitis, Scrotal abscess (12 Dec 1998) |
| cancer, testicular | Cancer of the male sex organ (testicle) that normally produces the hormone testosterone. One of the most common cancers in young men. Most testicular cancers are found by men themselves as a lump in the testicle. The risk of cancer of the testicles is increased in males whose testicles did not move down normally into the scrotum (holding sac for the testicles) during development if the problem is not corrected in early childhood. This condition is referred to as undescended testicles. When a growth in the testicle is detected, cancer is confirmed after surgical removal of the affected testicle (orchiectomy) and examination of the tissue under a microscope. Testicular cancer is almost always curable if it is found early. (12 Dec 1998) |
| crossed testicular ectopia | Testis that has crossed the midline to join its contralateral mate in the contralateral inguinal canal or hemiscrotum. (05 Mar 2000) |

| testicular appendage | A vesicular nonpedunculated structure attached to the cephalic pole of the testis; a vestige of the cephalic end of the paramesonephric (mullerian) duct.

| testicular artery | <anatomy, artery> Origin, aorta; branches, ureteral, cremasteric, epididymal; distribution, testicle and parts designated by names of branches; anastomoses, branches of renal, inferior epigastric, deferential. Synonym: arteria testicularis, arteria spermatica interna, internal spermatic artery. (05 Mar 2000) |
| testicular biopsy | <procedure> The removal of a fragment of a testicle for examination under the microscope. (13 Jan 1998) |
| testicular cancer | <oncology> A malignant growth that arises from a glandular cell in the testis. Common symptoms include a painless testicular mass in a male between the ages of 15 and 35 years. Monthly self-examinations are recommended in those between the ages of 15 and 39 years of age. (13 Jan 1998) |
| testicular cord | A group of structures which go through the inguinal canal to the testis. The structures include the vas deferens, arteries, veins, lymphatic vessels, and nerves. (12 Dec 1998) |
| testicular duct | The secretory duct of the testicle, running from the epididymis, of which it is the continuation, to the prostatic urethra where it terminates as the ejaculatory duct. Synonym: deferent canal, deferent duct, spermatic duct, spermiduct, testicular duct, vas deferens. (05 Mar 2000) |
| testicular dysgenesis | A congenital derangement of seminiferous tubular structure and function, resulting in male infertility; the defect in spermatogenesis may be incomplete, as in maturational arrest or premature sloughing, or spermatogenesis may be completely absent, as in the Sertoli-cell-only syndrome.
