Surgery of the Male Reproductive Tract Surgeries performed on the male reproductive tract include:??
Orchiectomy (castration) Vasectomy Crushing of spermatic cord Inducing ischaemic necrosis of scrotum
The testis are located in an evagination of the peritoneum called the vaginal tunic. They are covered by the tunica albuginea and the visceral layer of vaginal tunic. Open castration involves cutting into the parietal layer of the vaginal tunic. The tunic and skin is then left open. Closed castration does not cut into the parietal layer of the vaginal tunic. Modified castration is open and subsequently closed castration. The parietal layer is cut into, vessels ligated and the skin closed.
1. Castration of the horse Castration of the horse may done standing with sedation and local anaesthesia. This is usually done as an open castration. For this procedure, an 8-10cm skin incision is made in the scrotum 2-3cm from the median raphe. This incision is carried through the skin and muscle. The vaginal tunic is opened and the testes pushed out. Fascia is stripped away using a dry gauze. The cord is emasculated wither as one portion or two depending on size, with or without an absorbable ligature. The remnant tunic is also emasculated. The tunic, sub-cutaneous tissue and skin are left open. Closed castration may also be done under general anaesthesia in the field. The technique is the same but the vaginal tunic is not opened. Transfixing sutures are normally placed through the tunic anchoring the vascular portion, and then
