The FOGSI position statement details the crucial role of progesterone in maintaining early pregnancy, highlighting its production by the corpus luteum and later by the placenta. It discusses the use of dydrogesterone and micronized progesterone in supporting pregnancy, particularly in cases of recurrent miscarriage and threatened miscarriage, indicating significant benefits in reducing miscarriage rates. Safety data suggest that these progestogens have no significant differences in congenital abnormalities, although caution is advised in patients with certain health conditions.
