The behaviour of the concentration of the selected pituitary hormones during hot flushes at women after a surgical castration was evaluated. The inquiry concerned 42 women 46.7 +/- 3.4 years old, with a regular menstruation till the hysterectomy and the adnexectomy due to sexual organs diseases. The inquiry contained a determination, by means of radioimmunological methods, of the concentration of the hormones: LH, FSH, PRL, HGH, TSH in the blood serum taken at women 48 hours before the operation, on the 8th day after the intervention and 5 min after the hot flushes apparition. At the same time, the finger skin temperature and the pulse rate was taken. The rise in the finger skin temperature by 1.2 degrees C and the mean rise in the pulse rate by 11.3 beats/min during hot flushes were noticed. An important increase of the LH and HGH concentration during hot flushes was also observed.

Many changes in the neuroendocrine axis occur with healthy normal aging in humans. Women cease ovarian follicle maturation and menstrual cycles entering the estrogen-deficient state termed menopause. Although not without risk, estrogen and progesterone replacement in postmenopausal women has been shown to ameliorate the complications of lowered estradiol concentrations, such as hot flushes and osteoporsis, while improving the risk of cardiovascular complications. Aging men have lowered serum free and total testosterone concentrations and may experience a less well defined symptom complex termed andropause. Both signs and symptoms of thyroid disease and interpretation of thyroid function tests are difficult in aging humans. Specifically, TSH secretion is diminished in aging so that suppressed serum TSH concentrations are indicative of but not specific for hyperthyroidism. Cortisol secretion is not altered in aging, although serum concentrations of DHEA-S are lower. Prolactin concentrations are increased in both men and women, with the increase being more pronounced in men. The clinical significance of this increase has not yet been determined. Finally, elderly humans are more likely to develop difficulties with fluid and electrolyte balance. Although some alterations in AVP secretion have been shown in the elderly, plasma concentrations are similar in young and elderly subjects. Other mechanisms, such as decreased glomerular filtration rate and a decreased sensitivity of the thirst mechanism in response to hypertonicity, may be important contributors to fluid and electrolyte imbalances.

In this paper, the association of hormones to vasomotor complaints during the menopausal transition is discussed. Fifty-seven regularly menstruating women without history of hormone replacement therapy (HRT) were selected for a longitudinal, prospective study around the menopausal transition. The mean age at the start of the study was 51.3 (+/-2.0) years. At intervals of 12 months all women went through a semi-structured interview and filled in questionnaires. Venous blood samples were collected every 12-month for analyses of estradiol (E2), testosterone, androstendione, dehydroepiandrosterone-sulphate (DHEA-S), follicle stimulating hormone (FSH), thyrotropin (TSH), and luteinizing hormone (LH). Vasomotor complaints were tested using questions about hot flushes and bouts of sweating in terms of occurrence, frequency and degree of distress. Forty-six percent of the subjects reported hot flushes and bouts of sweating before menopause, increasing to 67% during the first year after menopause and 49% in the second year postmenopause. Low levels of estradiol and high levels of FSH were associated with vasomotor complaints before menopause. During menopause high levels of TSH were related to vasomotor complaints. The first year after menopause, women, who at this point achieved hot flushes, were characterised by high levels of E2, but declining and low levels of FSH, but increasing. Postmenopausal, high levels of testosterone and DHEA-S seemed to protect against vasomotor symptoms. Our most important finding was, that among women who achieved hot flushes at the first assessment postmenopause, the high androgen levels was a significant predictor of recovery from hot flushes at the last assessment, 1 year later.

Premature ovarian failure (POF) is the occurrence of hypergonadotropic hypoestrogenic amenorrhea in women under the age of forty years. It is idiopathic in 74-90% patients. Known cases can be divided into primary and secondary POF. In primary POF genetic aberrations can involve the X chromosome (monosomy, trisomy, translocations, deletions) or autosomes. Genetic mechanisms include reduced gene dosage and non-specific chromosome effects impairing meiosis, decreasing the pool of primordial follicles and increasing atresia due to apoptosis or failure of follicle maturation. Autoimmune ovarian damage is caused by alteration of T-cell subsets and T-cell mediated injury, increase of autoantibody producing B-cells, a low number of effector/cytotoxic lymphocyte, which decreases the number and activity of natural killer cells. Bilateral oophorectomy, chemotherapy, radiotherapy and infections cause the secondary POF. Symptoms of POF include irritability, nervousness, loss of libido, depression, lack of concentration, hot flushes, weight gaining, dry skin, vaginal dryness, frequent infections etc.The diagnosis is confirmed by the level of FSH of over 40 IU/L and estradiol below 50 pmol/L in women aged below 40 years. Biochemical and other hormonal analysis (free thyroxin, TSH, prolactin, testosterone), karyotype (<30 years of age), ultrasound of the breasts and pelvis are advisable. Optimal therapy is combined estrogen progestagen therapy given in a sequential rhythm, after excluding absolute contraindications. Testosterone can be added to adnexectomized women and those with a low libido. Sequential estrogen progestagen replacement therapy is the first line therapy for ovulation induction in those looking for pregnancy and after that oocyte donation will be advised. Appropriate estro-progestagen therapy improves the quality of life and prevents complications such as cardiovascular diseases, osteoporosis, stroke etc.
