Orchitis can be related to epididymitis infection that has spread to the testicles (then called "epididymo-orchitis"), sometimes caused by the sexually transmitted infections chlamydia and gonorrhea.
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 epididymis (/ ɛ p ɪ ˈ d ɪ d ɪ m ɪ s /; pl.: epididymides / ɛ p ɪ d ɪ ˈ d ɪ m ə d iː z / or / ɛ p ɪ ˈ d ɪ d ə m ɪ d iː z /) is an elongated tubular genital organ attached to the posterior side of each one of the two male reproductive glands, the testicles.
The appendix testis is a Müllerian duct remnant and consists of fibrous tissue and blood vessels within an envelope of columnar epithelium. The appendix testis is attached to the upper pole of the testis and found in the groove between the testis and the epididymis. The appendix epididymis is attached to the head of the epididymis.
testicular microlithiasis on ultrasound. Testicular microlithiasis is an unusual condition diagnosed on testicular ultrasound. It is believed to be found in 0.1–0.6% of males globally, with frequency varying based on geographic location and is more often found in individuals with subfertility.
The juxtaoral organ in humans is a small longish structure (10–14 mm in length, 1–2 mm in diameter), situated medially to the medial pterygoid muscle. The organ consists of a central ramified cord of epithelial parenchyma, embedded in connective tissue particularly rich in nerve fibers and sensory receptors.
As the scrotum and labia majora form in males and females respectively, the gubernaculum aids in the descent of the gonads (both testes and ovaries). [3] The testes descend to a greater degree than the ovaries and ultimately pass through the inguinal canal into the scrotum. [3] The mechanism of this movement is still debated. [3]
The tunica albuginea is a dense, [1] [2] blue-white [3] layer of fibrous tissue surrounding the testis. [1] [4] It is the middle of three envelopes forming the capsule of the testis; it is deep to the visceral layer of tunica vaginalis, and superficial to the tunica vasculosa testis (vascular layer of testis).
