Abstract
An orchiopexy was performed in an 18-month old adult English bulldog with bilateral cryptorchidism. One month postoperatively, the dog was twice-treated with GnRH (50 ug/kg) at an interval of 2 weeks. Semen was collected and evaluated before and after surgery. Fertility was determined by artificial insemination. No spermatozoa were observed before orchiopexy and 2 months postoperatively. However, 6 live sperm were detected 4 months postoperatively and normal sperm characteristics (except sperm concentration) were present 7 months postoperatively. A female bulldog, inseminated with the semen from the bulldog 8 months postoperatively, delivered 6 offsprings. Spermatogenesis and spermatozoa with fertilizing capacity were recovered by postpubertal orchiopexy and GnRH therapy in a bilateral cryptorchid dog.
