Pituitary function tests in black patients with pseudocyesis.
Pituitary function was evaluated in a group of 10 patients with pseudocyesis. One patient was postmenopausal; the remainder demonstrated normal basal prolactin, luteinising hormone (LH) and follicle-stimulating hormone (FSH) levels and also normal pituitary-adrenal, pituitary-thyroid axes. Oestradiol deficiency was present in 6 patients, while 2 patients demonstrated elevated serum progesterone values, suggestive of a luteal phase. Gonadotrophin-releasing hormone administration resulted in exaggerated stimulation of LH and FSH in 4 and 2 patients, respectively. Impaired growth hormone (GH) secretion was present in 6 patients after insulin-induced hypoglycaemia and L-dopa administration. GH impairment is probably a consequence of the oestrogen deficiency that commonly occurs in this condition. It thus appears that there are aberrations in specific pituitary hormone responses after provocation in pseudocyesis.
