Classical Roman law, that is Roman law until the end of the second century AD, did not contain the unus testis-rule according to current scholarly understanding, even though D. 22.5.12 [γ] – a passage of the Digest attributed to the early 3rd century Roman jurist Ulpian – had historically been understood as evidence for the existence of such a rule during this period.
Cryptorchidism, also known as undescended testis, is the failure of one or both testes to descend into the scrotum. The word is from Ancient Greek ...
The lower part persists as the gubernaculum testis ("scrotal ligament"). This ligament secures the testis to the most inferior portion of the scrotum, tethering it in place and limiting the degree to which the testis can move within the scrotum. Cryptorchidism (undescended testes) are observed in INSL3-null male mice.
The undescended testis is at increased risk of testicular torsion. [17] The mechanism for torsion in the undescended testicle is not fully understood, though it may be due to abnormal contractions of the cremaster muscle, which covers the testicle and spermatic cord and is responsible for raising and lowering the testicle to regulate scrotal ...
The ectopic testis can be in the perineal region, the opposite side of the scrotum, the suprapubic region, the femoral region, or the superficial inguinal pouch. [1]The ectopic testis is initially normal, but if it is ignored after childhood, it may become small and soft, with spermatogenesis arresting and interstitial cell proliferation occurring.
A man is measuring his testis with an orchidometer.. The orchidometer was introduced in 1966 by Swiss pediatric endocrinologist Andrea Prader of the University of Zurich. [1] It consists of a string of twelve numbered wooden or plastic beads of increasing size from about 1 to 25 millilitres.
The rete testis (/ ˈ r iː t i ˈ t ɛ s t ɪ s / REE-tee TES-tis; pl.: retia testes) is an anastomosing network of delicate tubules located in the hilum of the testicle (mediastinum testis) that carries sperm from the seminiferous tubules to the efferent ducts. It is the homologue of the rete ovarii in females. [1]
The tunica vasculosa testis (vascular layer of testis) is the inner-most of the three layers that form the capsule of the testis. It consists of a vascular plexus and loose connective tissue . It extends into the testis itself to line the surfaces of individual septa of testis .
