The administration of progesterone in injectable or vaginal form is more efficient than by the oral route, since it avoids the metabolic losses of progesterone encountered with oral administration resulting from the hepatic first-pass effect (32). In addition, the injectable forms avoid the need for higher doses that cause a fairly large number of side-effects, such as somnolence, sedation, anxiety, irritability and depression (33).
