What is a Muller pregnancy?

did you mean molar pregnancy? if so it is a pregnancy that results in a tumor or growthfrom the placenta inside the uterus and if it is a true molar there usually is not a fetus involved. if there is a fetus it has many defects and it is miscarried. treatment is removal of all growth and periodic hcg testing for the next 6 to 12 months. hope that helps.
