[Pregnancy in a patient with resistant ovary syndrome--a case report].

Resistant ovary syndrome (ROS) and premature ovarian failure (POF) represent two forms of hypergonadotropic hypogonadism. Principal symptoms include primary or secondary amenorrhea (before the age of 40 years), low levels of estradiol and elevated FSH (above 40IU/ml) in serum. The main difference is the presence of follicles in ROS which is tantamount to the possibility of pregnancy. We present the case of pregnancy in a 31-year-old patient who was initially diagnosed with POF, which was the basis of the final diagnosis of ROS.
