What is the function of spermatogonia?
Formed from germ stem cells - form sperm by the process of spermatogenesis
What is the function of sertoli cells:
Supportive cells - produce nutrients, cytokines to support spermatogenesis (also support the blood testis barrier
What is the function of Leydig cells?
Produce testosterone - maintaining secondary sex characteristics
Why is maintaining the blood testis barrier important and what are the consequences if this breaks down?
Maintaining the blood-brain barrier is critically important - the body recognises as foreign so spermatic granulomas form in the event of degeneration of this barrier
What is the term for inflammation of the penis?
Phallitis = inflammation of the penis
What is the term for inflammation of the glans?
Balantitis
What is the term for inflammation of the prepuce?
Posthitis
Name the condition below and the aetiologic agent that caused it:
Penile fibropapilloma - BPV1
Provide three differentials for the lesion that is shown below:
- Penile squamous cell carcinoma - induced by UV or malignant transformation of a papillomavirus induced papilloma
- Chronic granulomatous phallitis
- Habronemiasis (caused by flies depositing larvae around mouth + penis)
Name the condition that is shown below and provide a pathogenesis for it:
Necrotic posthitis (pizzle rot)
Caused by urease producing bacteria: Occurs where the diet is high in protein > urea > production of urease producing bacteria (can become so severe that inflammation blocks the urethra)
Name the condition that is shown below and provide a pathogenesis for it:
Preputial diverticulitis: significant problem in boars - boars are the only animal witha. diverticulum (sac like space in the prepuce)
The tip of the penis deflects up into the orifice due to malformation (congential or acquired) > trauma of diverticulum > secondary infection
Name the condition that is shown below and state how it is spread:
Transmissible venereal tumour: tumour has arisen from specific alteration of canine histiocytes > transmitted dog to dog by contact of tissue with other animals
What is inflammation of the testicle called?
Orchitis
What is inflammation of the epididymus called?
Epididymitis
What is the lesion that is shown below called and what could be a potential consequence of it?
Cryptorchidism - more likely to be neoplastic
