Featured Blog: Declining Fertility in the Aged Stallion

Age-related testicular degeneration is a common problem in older stallions. This type of testicular degeneration is different than the degeneration that can be seen after, for example, an injury to the testes in a younger stallion. Following testicular trauma, many stallions are able to fully recover. However, age-related testicular degeneration results in progressive deterioration of the testes and an associated progressive decline in testicular function. Over time, affected stallions become progressively more subfertile and eventually may become sterile in association with decreases in semen quality, sperm numbers and testicular size. There is no proven treatment for age related testicular degeneration, although many therapies have been tried.  In this article, Dr. Regina Turner of the New Bolton Center at the University of Pennsylvania, discusses the causes of age-related testicular degeneration, current research and how one can manage the breeding career of an aged stallion until a treatment or cure is found.

Featured Question

Do I or my vet need special tanks to hold frozen semen?

No. Select Breeders Service will ship enough frozen semen to manage the mare through one complete heat period. The shipping tanks are specially designed cryogenic vessels which maintain the frozen semen at -196°C for at least 10 days. This allows SBS to ship the semen to your vet well in advance of the anticipated insemination date avoiding the last minute rush to schedule semen shipments associated with cooled transported semen breeding. Also, if the mare fails to ovulate when predicted, no further shipments are required. There are sufficient doses of frozen semen in the tank to inseminate the mare again as needed. Of course, if you or your veterinarian own a liquid nitrogen storage tank, the semen could be transferred to this tank for storage.
