Editing Gelding (section)

==Time of gelding==
A horse may be gelded at any age; however, if an owner intends to geld a particular foal, it is now considered best to geld the horse prior to becoming a yearling,<ref name=Liphook>[http://www.liphookequinehosp.co.uk/castration.htm Archived copy] {{webarchive |url=https://web.archive.org/web/20061007105852/http://www.liphookequinehosp.co.uk/castration.htm |date=October 7, 2006 }}</ref> and definitely before he reaches sexual maturity. While it was once recommended to wait until a young horse was well over a year old, even two, this was a holdover from the days when castration was performed without [[anesthesia]] and was thus far more stressful on the animal. Modern veterinary techniques can now accomplish castration with relatively little stress and minimal discomfort, so long as appropriate [[analgesics]] are employed.<ref>R Eager (2002) "Evaluation of pain and discomfort associated with equine castration" UFAW Publications</ref> A few horse owners delay gelding a horse on the grounds that the [[testosterone]] gained from being allowed to reach sexual maturity will make him larger. However, recent studies have shown that this is not so: any apparent muscle mass gained solely from the presence of hormones will be lost over time after the horse is gelded, and in the meantime, the energy spent developing muscle mass may actually take away from the energy a young horse might otherwise put into skeletal growth; the net effect is that castration has no effect on rate of growth (although it may increase the amount of fat the horse carries).<ref>Seong, PN; Lee, CE, and Oh, WY; et al.

Many older stallions, no longer used at stud due to age or sterility, can benefit from being gelded. Modern veterinary techniques make gelding an even somewhat elderly stallion a fairly low-risk procedure,<ref name="mason">Mason, BJ, Newton, JR &amp; Payne, RJ, et al. (2005). [http://onlinelibrary.wiley.com/doi/10.2746/042516405774479988/full Costs and complications of equine castration: a UK practice-based study comparing 'standing nonsutured' and 'recumbent sutured' techniques]. ''Equine Veterinary Journal'' 37.5:468–472.</ref> and the horse then has the benefit of being able to be turned out safely with other horses and allowed to live a less restricted and isolated life than was allowed for a stallion.
