testis (redirected from retractile testis)

testis /tes·tis/ (tes´tis) pl. tes´tes   [L.] the male gonad; either of the paired egg-shaped glands normally situated in the scrotum, in which the spermatozoa develop. Specialized interstitial cells (Leydig cells) secrete testosterone.

abdominal testis  an undescended testis in the abdominal cavity.

ectopic testis  one outside the normal pathway of descent.

obstructed testis  one whose normal descent is blocked, so that it goes into an inguinal pouch.

retained testis  undescended t.

retractile testis  one that can descend fully into the scrotum but then moves freely up into the inguinal canal.

undescended testis  one that has failed to descend into the scrotum, as in cryptorchidism.

testis

[tes′tis] pl. testes [tes′tēz′]

one of the pair of male gonads that produces sperm and testosterone. The adult testes are suspended in the scrotum by the spermatic cords; in early fetal life they are contained in the abdominal cavity behind the peritoneum. Before birth they normally descend into the scrotum. The coverings of the testes are the skin and the dartos tunic of the scrotum, the external spermatic fascia, the cremasteric layer, the internal spermatic fascia, and the tunica vaginalis. Each testis is a laterally compressed oval body about 4 cm long and 2.5 cm wide that weighs about 12 g. It is positioned obliquely in the scrotum, with the cranial extremity directed ventrally and slightly laterally and the caudal end directed dorsally and slightly medially. The anterior border, lateral surfaces, and extremities of the organ are convex, free, smooth, and covered by the tunica vaginalis. The convoluted epididymis lying on the posterior border of the testis contains a tightly coiled tube that is about 20 feet long and connects with the vas deferens through which spermatozoa pass during ejaculation. Each testis consists of several hundred conical lobules containing the tiny coiled seminiferous tubules, each about 75 mm long, in which spermatozoa develop. In early life the tubules are pale in color, but in old age they become invested with yellow fatty matter. The tubules converge to form the rete testis, which is drained by the efferent ducts into the head of the epididymis. The testes are supplied with blood by the two internal spermatic arteries that arise from the aorta, are served by the testicular veins that form the pampiniform plexuses constituting the greater part of the spermatic cords, and are innervated by the spermatic plexuses of nerves from the celiac plexuses of the autonomic nervous system. Also called testicle. Compare ovary. See also scrotum. testicular, adj.

testis

pl. testes [L.] the male gonad; either of the paired, egg-shaped glands normally situated in the scrotum; called also testicle. The testes produce the spermatozoa, the male reproductive cells, which are ejaculated into the female vagina during coitus, and the male sex hormone, testosterone, which is responsible for the secondary sex characters of the male.

ectopic testis

the testis is in an abnormal position away from the normal descent pathway.

nonscrotal testis

includes ectopic and cryptorchid testis.

retained testis

see cryptorchid.

supernumerary testis

polyorchidism.

testis tubuli contorti

seminiferous tubule.

undescended testis

see cryptorchid. Called also retained testicle.

Patient discussion about retractile testis.

Q. Has anyone ever had Epididymitis? I was just diagnosed with it and want to know what to expect. Thanks

A. They normally treat you for it as if you have an STD. If you have not been sexually active, then the antibiotics they will give you will not make a difference.

Bed rest is important so that the swelling can go down.
