Mechanism of action

Progesterone is a naturally occurring steroid hormone essential for preparing and maintaining the uterine endometrium for embryo implantation and pregnancy. In assisted reproductive technology, exogenous progesterone supplementation compensates for inadequate corpus luteum function, ensuring sufficient endometrial receptivity and preventing premature menstruation. The oil formulation provides sustained intramuscular absorption and prolonged systemic progesterone levels.
