Mice are typically injected with PMSG to stimulate follicle growth and later injected with hCG to induce ovulation. hCG is made by the embryo soon after conception and later by the syncytiotrophoblast. hCG prevents the disintegration of the corpus luteum and thereby maintains progesterone production, critical for human pregnancy. hCG may affect immune tolerance of the pregnancy. Early pregnancy testing is usually based on hCG detection/measurement.
