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 ...
Syphilis (/ ˈ s ɪ f ə l ɪ s /) is a sexually transmitted infection caused by the bacterium Treponema pallidum subspecies pallidum. [1] The signs and symptoms depend on the stage it presents: primary, secondary, latent or tertiary.
Testicular cancer is when malignant cells grow in the tissues of the testicles. Males are at higher risk of testicular cancer between the age of 15-35 years old. Testicular cancer signs include swelling and fluid build up in the scrotum. Other signs can be pain, and any new lumps in the testicles. Testicular cancer is confirmed by CT scans or ...
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.
Previous testicular cancer; The diagnosis is confirmed in different ways. An ultrasound scan can be used to diagnose to a 90-95% accuracy. Bloods can also be taken to look for elevated tumour markers which is also used to analyse the patient's response to treatment. 80% of testicular cancer cases are from the 20-34 year old age range [18]
According to Prehn's sign, the physical lifting of the testicles relieves the pain of epididymitis but not pain caused by testicular torsion. [ 4 ] Negative Prehn's sign indicates no pain relief with lifting the affected testicle, which points towards testicular torsion which is a surgical emergency and must be relieved within 6 hours.
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.
Sertoli cell-only syndrome (SCOS), also known as germ cell aplasia, is defined by azoospermia where the testicular seminiferous tubules are lined solely with sertoli cells. [2] Sertoli cells contribute to the formation of the blood-testis barrier and aid in sperm generation.
