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.
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 most common presentation of testicular cancer is a hard, painless lump which can be felt on one of the testis. It is either noticed by a clinician during a routine examination, or the patient themselves. [17] Risk factors for TC include: Cryptorchidism; Family history; Previous testicular cancer; The diagnosis is confirmed in different ways.
Infertility is the most prevalent symptom of Sertoli-cell-only syndrome. Semen examination reveals azoospermia, with sperm density frequently falling to fewer than 1 million sperm per mL.
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 mediastinum testis is a thick yet incomplete septum at the posterior part of the testis formed by the tunica albuginea of testis projecting into the testis at its posterior aspect where the testis is not lined by the serous membrane to allow for the attachment of the epididymis.
