Can anyone comment on using this method for insemination, especially with low dose or low fertility frozen semen? Any references or experiences firsthand?

We had a healthy colt foal born last year who was conceived by video endoscopic insemination using 1/4 of a dose of frozen semen.There was a semen shortage (Sandro Hit).This was done at the Equine Fertility Unit in Newmarket by Twink Allen on a maiden mare who conceived to first insemination.If there was a problem I would definatly use this method again.

Very valuable method for use with low sperm numbers, as Cheryl attests. Note however that research (Squires et. al.) has shown that using a standard insemination dose with deep horn insemination actually lowers pregnancy rates when compared with standard insemination methods. With low doses, the fertility exceeded standard methods.
Can one postulate that if using deep horn insemination, it is better to use a smaller dose of semen?
In other words, if you have enough semen for a full dose, but, are opting to do deep horn, should you reduce the volume of the dose?
