Pinhole Castration?

[ZeuterMe (imported)]

Anybody ever hear of pinhole castration? It's a subdermal ligation a little like banding, but without the chance of infection. It takes only a minute or three to perform, and it's being discussed for birth control in domestic animals. Likewise, there's a pinhole epididymal ligation developed based on it; it's being used to prepare teaser rams - sterile but virile - in a cheaper, safer fashion than vasectomy.

I'd love to post pictures, but they don't want to upload. Help?

We don't allow pictures. Someone some time back had an extensive thread going here about this method, apparently used with some mixed results. Search around for it.

METHODS: Calves were blocked by weight and then separated into 3 groups: (1) bilateral spermatic cord ligation; (2) unilateral-1 spermatic cord ligated; and (3) control-neither spermatic cord ligated. After local anesthesia, in situ spermatic cord ligation was achieved by restraining the cord laterally within the scrotal sac and passing suture through a hypodermic needle inserted caudal to cranial at the neck of the scrotum and adjacent the medial margin of the restrained spermatic cord. The needle was removed leaving the suture in place and the spermatic cord repositioned medially, then the needle was reinserted through the original holes and the suture passed back through the needle, which was withdrawn. The suture ends were tied ligating the spermatic cord, leaving the knot subcutaneously. Calves were monitored and testes removed after 30 days for gross and histologic examination.

RESULTS: Castration was accomplished without postoperative complications. Spermatic cord ligation resulted in testis atrophy, and histologically, complete ischemic necrosis.

CONCLUSIONS: This novel minimally invasive technique is a simple, alternative method for castration of bull calves.

CLINICAL RELEVANCE: This method of castration is simply performed, without obvious skin wounds, and no postoperative care needed. The technique should be readily adaptable to other species.

Apart from the difficulty of obtaining local anesthesia this looks like a promising technique for a DIY castration procedure that could easy be carried out in the privacy of your own home,my only concern is what happens when one goes to the doctor with atrophied testicles,will the doctor then be able to tell that a pinhole has been carried out, if so what will be their reaction.be?

If you do, perhaps later on it would appear to be an old torsion? As for anesthesia, the procedure is probably less painful than the more-popular injections straight into the testicle - the goal, after all, is to miss all the structures inside the scrotum, not nail one of the big ones. However, with the goal of reducing blood flow, the discomfort later on might be comparable to banding - or it might not. There's only specific kinds of nerves in the testicle, after all. How much does a torsion actually hurt, anyway? Also, from Healthline,

Testicular torsion usually occurs in only one testicle. Bilateral torsion, when both testes are simultaneously affected, is extremely rare. The simple fact of two torsions happening simultaneously at a similar elevation should itself be considered suspicious.
