A comparison of the psychological and hormonal factors in women with and without premenstrual syndrome

Changes in plasma hormones across the menstrual cycle in patients with menstrually related mood disorder and in control subjects

Rubinow DR et al., 1988 · Am J Obstet Gynecol

A variety of hypotheses have been proposed to explain the premenstrual syndromes. These hypotheses serve as rationales for an equally diverse range of proposed treatments. To investigate these hypotheses, we obtained multiple blood samples across the menstrual cycle in women with well-characterized menstrually related mood disorder and in control subjects. No diagnosis-related differences were observed in the levels or patterns of secretion of progesterone, estradiol, follicle-stimulating hormone, luteinizing hormone, testosterone-estradiol-binding globulin, dehydroepiandrosterone sulfate, dihydrotestosterone, prolactin, or cortisol. Our data suggest that premenstrual syndrome does not represent a simple hormonal deficiency and that the cited rationales for several of the proposed treatments are of questionable merit.

Whole-blood serotonin in premenstrual syndrome

Rapkin AJ et al., 1987 · Obstet Gynecol

Whole-blood serotonin levels in 14 subjects with well documented premenstrual syndrome and 13 age-matched controls were compared. Serotonin levels of premenstrual syndrome subjects were significantly lower during the last ten days of the menstrual cycle. No significant differences were noted in levels of serum estradiol and progesterone. Decreased serotonin is known to be associated with depression in humans, and nonhuman primates have exhibited abnormal behavioral profiles when given serotonin antagonists. The present observation suggests that the physiologic basis of premenstrual syndrome involves an alteration in serotonin metabolism.

Endocrine profiles in premenstrual tension

Adamopoulos DA et al., 1972 · Clin Endocrinol (Oxf)

Studies on pituitary and ovarian function as assessed by the urinary output of total gonadotrophic activity, the three classical oestrogens, pregnanediol and, in some cases, testosterone and epitestosterone, were conducted in eight patients suffering from premenstrual tension. Major abnormalities in endocrine function were not a feature of the condition. Ovulation, as judged by pregnanediol assays, was absent in seven out of the fifteen cycles investigated. Contrary to traditional belief, the symptoms of premenstrual tension could exist in the presence of cycles with anovulatory hormonal patterns.
