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 103 sexually mature women with disturbance of ovulation, a possible relationship between Kupperman menopausal complaints and endocrinological status was investigated to find the cause of climacteric syndrome. The Kupperman index was increased as the disturbance of ovulation was advanced from the stage of anovulatory cycle to amenorrhea I and further to amenorrhea II. In parallel with the advance in disturbance of ovulation, serum FSH and LH levels rose significantly, and serum estrone (E1) and estradiol (E2) levels dropped. Prolactin (PRL) showed a tendency to decrease. There were some hormonal patterns characteristic of individual complaints; hot flush was associated with increased FSH and LH, and decreased E1 and E2; difficulty in falling asleep, excitability, and fatigability, with increased FSH and LH, and decreased E2; nervousness, with increased LH and decreased E2; headache, with increased LH and PRL, and decreased E2; feeling of cold, with decreased E2 and PRL; and numbness and shoulder stiffness, with decreased E2. In sexually mature women, the complaints associated with abnormal levels of two or more kinds of hormones seemed to be most specifically related with decreased E2, followed by increased LH. Fatigability and headache developed specifically in the ovulatory phase of women with normal menstrual cycles (105 subjects), suggesting that these two complaints are closely related to increased LH. These results indicate that the majority of Kupperman menopausal complaints have their individually specific endocrinological cause, and that they may develop even in sexually mature women if those specific conditions exist. In climacteric syndrome in a narrow sense (i.e., dysautonomic type), each complaint may also have its specific endocrinological cause.

A percutaneous gel containing 0.6 mg/g of estradiol-17 beta was used for cyclic replacement therapy in 19 postmenopausal women. Significantly increased serum concentrations of estradiol-17 beta, unconjugated estrone, and total estrone were recorded during 6 months of treatment. In contrast to oral treatment the quotient of estrone/estradiol-17 beta was maintained and even reduced during therapy. Significant gonadotropin inhibition was recorded and the estrogenic potency of 3 mg percutaneous estradiol-17 beta was similar to that of oral estradiol-17 beta 2 mg and 2.5 mg oral estrone sulphate. Prolactin levels remained constant during treatment. Therapy was effective in abolishing hot flushes in 17 out of the 19 women treated. The therapy was well accepted by the volunteers. Seventeen out of 19 women stated that the gel was easy to use in everyday life. Topic application may develop into an alternative treatment for climacteric complaints and may even have some metabolic advantages over oral treatment.

Prolactin-secreting adenoma is rare in elderly women. Patient's clinical picture may be confused with that of menopause, making diagnosis sometimes difficult. We report the case of a 57-year old woman with a 2-year history of secondary amenorrhea without hot flushes associated with galactorrhea in order to highlight the peculiarities of prolactin-secreting microadenomas. Physical examination confirmed the diagnosis of galactorrhoea and biology showed hyperprolactinemia at mIU/L, FSH = 15.1 IU/L and LH = 4,1 IU/L. Pituitary MRI showed left adenoma measuring 8 mm. Patient's evolution under dopaminergic treatment was marked by the recovery, for a transitional period, of mestrual cycles and the occurrence of hot flushes, normalization of prolactin levels and reduction of adenoma size.
