Ontology and endocrinology of the reproductive system of bulls from fetus to maturity

A good understanding of prenatal and post-natal development of the reproductive system of bulls and the factors affecting this development provides the basis for ‘best practice’ recommendations on the management of pregnant seedstock dams and management of young bulls through to them either, becoming herd sires or semen donors. Both prenatal and postnatal development of the reproductive system is controlled by interactions between genetic and environmental factors. Some disturbances in development may be diagnosed prior to puberty but some such as unilateral testicular hypoplasia and premature spiral deviation of the penis may not manifest until months to several years after bulls reach puberty.
