  • Title: [Impulse secretion of gonadotropins in patients with various forms of amenorrhea].
    Author: Zemchenkova IG, Potin VV, Svechnikova FA.
    Journal: Probl Endokrinol (Mosk); 1992; 38(3):28-30. PubMed ID: 1513786.
    Abstract:
    Circahoral variations of gonadotropin secretion were investigated in 5 healthy women in the follicular phase of the menstrual cycle, in 8 patients with normogonadotropic amenorrhea, in 6 patients with hyperprolactinemic amenorrhea, in 4 patients with hypogonadotropic amenorrhea, and in 10 patients with amenorrhea associated with body mass deficiency. The levels of LH, FSH, prolactin, estradiol and progesterone were determined by radioimmunoassay every 20 min for 4 hours. The results suggest that the blood levels of gonadotropins in different types of amenorrhea are determined mainly by an amplitude of their impulses.
