| 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 | <anatomy> Pertaining to a testis. (18 Nov 1997) |
| 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. (05 Mar 2000) |
| testicular feminisation | <endocrinology> if genetic males lack receptors for testosterone they develop as females and are unresponsive to male hormones. (13 Jan 1998) |
| testicular feminization | A condition, due to lack of cellular receptors for testosterone and dihydrotestosterone, in which the subject is phenotypically female but lacks nuclear sex chromatin and is of xy chromosomal sex. The uterus and tubes are absent or rudimentary, and the gonads are typically testes and may be abdominal or inguinal in position. The incomplete form is marked by partial fusion of the labioscrotal folds and clitoromegaly, and at puberty, variable feminization and partial virilization may both take place. (12 Dec 1998) |
| testicular feminization syndrome | <syndrome> A type of male pseudohermaphroditism characterised by female external genitalia (may be ambiguous if the syndrome is incomplete), incompletely developed vagina often with rudimentary uterus and fallopian tubes, female habitus at puberty but with scanty or absent axillary and pubic hair and amenorrhoea, and testes present within the abdomen or in the inguinal canals or labia majora; epididymis and vas deferens are usually present; androgens and oestrogens are formed, but target tissues are largely unresponsive to androgens; individuals are sex chromatin-negative and have a normal male karyotype; X-linked recessive inheritance; there is a defect in the androgen receptor protein. (05 Mar 2000) |
| testicular hormones | Hormones produced in the testis. (12 Dec 1998) |
| testicular implant | A device placed surgically in the scrotum in males with absence or severe hypoplasia of the testis. Synonym: testicular prosthesis. (05 Mar 2000) |
| testicular microlithiasis | <radiology> Ultrasound features: multiple intratesticular non-shadowing echogenic foci, size: 1 - 3 mm, variable number, distribution: usually diffuse pathology: cellular degeneration, central calcified core clinical significance: prevalence: 0.05-0.6%, possible association with primary testicular malignancy, association: cryptorchid testes, infertility Ref: Backus et al., Radiology 1994; 192:781-785 (12 Dec 1998) |
| testicular plexus | The autonomic plexus derived from the aortic plexus and accompanying the testicular artery. Synonym: plexus testicularis, spermatic plexus. (05 Mar 2000) |
