There are short paired uterine horns that join to form a fairly large thin-walled vagina within the abdominal cavity. The testes are located in the craniocaudal direction with dorsolateral epididymal attachments. Neutering male hedgehogs is also key to preventing testicular cancer and can also be done around the same age as the females.

1 In common with all hedgehogs except the long-eared genera the African pygmy hedgehog has a narrow spineless tract on the crown of the head which runs rostrocaudally for about 2 cm and is about 05 cm wide. Signs depend on the location and severity of disease and may include palpable masses weight loss anorexia lethargy diarrhea dyspnea and ascites. 20 Short 75 mm fallopian tubes emerge from each side of each uterine horn and the mesosalpinx and ovarian bursa are.
