[Pseudocyesis: clinical and hormonal evaluation].

Hormonal and clinical evaluation was performed in eleven females with diagnosis of pseudocyesis. Plasma levels of pituitary gonadotropins (FSH-LH), progesterone, estradiol and thyroid hormones (T3, T4, TSH) under basal conditions were measured through radioimmunoassay. Diagnosis of pseudocyesis was made according to the following criteria: a) secondary amenorrhea (greater than 12 weeks); b) two or more symptoms of gestation; c) conviction of being pregnant; d) negative HCG or pelvic ultrasound study. The circulation levels of gonadotropins were within normal limits. Progesterone exhibited a ovulatory pattern and thyroid hormones were normal for every instance. Once case had slight hyperprolactinemia (26.0 ng/ml) with impaired gonadotropin production and ovulatory progesterone. All patients had galactorrhea. The psychological study disclosed a tendency toward depression. Our findings partially confirmed previous observations, differing basically on that we observed normal hormonal trend.
