Utero:
Has a shape that resembles a "Y". In non-pregnant females uterus body is approximately 2 to 4 cm long, while the horns are about 8 to 15 cm. The left horn (where they develop almost all pregnancies) is larger than the right. During copulation the male deposits sperm into the uterus and sperm migrate from there to the site of fertilization (oviducts).
Oviducts:
The oviducts are thin tubes of about 20 cm in length. Therefore descends to meet the egg and sperm and allow fertilization.
Ovaries:
These organs are oval shaped, reaching a diameter adult female greater than about 15 mm and a minor diameter of about 10 mm. They mature follicles release eggs containing half the genetic material of the future progeny. In non-pregnant adult females can be observed on the surface of ovarian follicles several approximately 3 to 4 mm in diameter, and larger one (8 to 12 mm). Both ovaries are active in alpacas and llamas but, as noted above, almost all pregnancies develop in the left uterine horn
