Recruitment of multiple follicular development for in vitro fertilization in the presence of a viable intrauterine pregnancy

Abstract

Stimulation of multiple follicular development was induced concurrent with a viable early intrauterine pregnancy; the infant was subsequently delivered at term. Despite the pregnancy, the ovaries responded successfully to gonadotropin stimulation. In addition, three recovered oocytes were successfully fertilized, and two subsequently cleaved. Thus pregnancy does not create a state of ovarian refractoriness or a hormonal milieu totally deleterious to the initial stages of embryo development.
