Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Menopause is a product of interrupted ovarian activity and decrease in its estradiol production. Herbal medicines as an alternative to hormone therapy are increasingly used by menopausal women. Elaeagnus angustifolia L. (Senjed in Persian) is a well-known herbal remedy with various therapeutic effects according to Iranian traditional medicine which is recommended to relieve the menopausal side effects. The aim of present study was to evaluate the effects of oral intake of whole fruit powder of E. angustifolia on the sex hormones profile in menopausal women. MATERIALS AND METHODS In present double-blind randomized placebo-controlled trial, 58 eligible women who were referred to Kamali Women Hospital (Karaj, Iran, 2017) were randomly assigned into herbal medicine (15 g E. angustifolia) and placebo (7.5 g cornstarch +7.5 g isomalt) groups. Initially and after 10 weeks of the treatment, serum levels of estradiol, progesterone, testosterone, follicle-stimulating hormone (FSH) and luteinizing hormone (LH) hormones were measured. RESULTS According to between-group analyses, the changes in the studied parameters were not significant between herbal medicine and placebo groups, except for joint pain that improved significantly in herbal medicine group. However, by within-group analysis the levels of FSH and FSH to testosterone showed a significant increase, whereas the level of progesterone decreased significantly after 10 weeks of E. angustifolia consumption. CONCLUSIONS The improvement of the sex hormone profile was not in a full accordance with Iranian folklore after E. angustifolia consumption in the present menopausal participants. However, considering a strong belief on the beneficial effects of E. angustifolia in Iranian folklore, a long-term studies of larger group participants are needed to evaluate the efficacy.

Vitamin D, menopause, and aging: quo vadis?
López-Baena, MT, Pérez-Roncero, GR, Pérez-López, FR, Mezones-Holguín, E, Chedraui, P
Climacteric : the journal of the International Menopause Society. 2020;(2):123-129
Abstract
Menopause and aging are associated with changes in circulating gonadal steroid hormones, insulin sensitivity, body composition, and also lifestyle and social coordinates. Vitamin D status influences different metabolic adjustments, aside from calcium-phosphorus and bone metabolism. The main blood marker used to measure endogenous vitamin D status is 25-hydroxyvitamin D. Aging is associated with increases in serum parathyroid hormone and alkaline phosphatase, and a decrease of serum calcium, phosphorus, and vitamin D metabolites. 25-Hydroxyvitamin D status is also influenced by the circannual rhythm of sun irradiation. Results of clinical association studies have not correlated with intervention trials, experimental studies, and/or meta-analyses regarding the role of vitamin D on different outcomes in women during their second half of life and the vitamin D supplementation dose needed to improve clinical endpoints. Discordant results have been related to the method used to measure vitamin D, the studied population (i.e., sociodemographics and ethnicity), study designs, and biases of analyses. Vitamin D supplementation with cholecalciferol or calcifediol may improve some metabolic variables and clinical outcomes in young postmenopausal and older women. Studies seem to suggest that calcifediol may have some advantages over other forms of vitamin D supplementation. Further studies are needed to define interventions with supplements and effective food fortification.

Journal of endocrinological investigation. 2020;(6):809-820
Abstract
BACKGROUND Perimenopausal women gain weight that may alter inflammatory status, endocrine equilibrium, and the intensity of vasomotor symptoms. OBJECTIVE To measure serum levels of markers related to adiposity, inflammation/angiogenesis and digestive metabolism and correlate them with body mass index (BMI), waist-to-hip ratio (WHR), metabolic parameters and menopausal symptoms (assessed with the 10-item Cervantes Scale [CS-10]). METHODS Serum of perimenopausal women (n = 24), STRAW stages-2 and -1, was analyzed using the Bio-Plex 200 System technology to assess 30 proposed analytes. The MetS was defined by the American Heart Association criteria and women were divided as: normal BMI (NBMI), excessive BMI (EBMI), and EBMI with MetS (EBMI-MetS). RESULTS Weight, BMI, abdominal circumference, WHR, systolic blood pressure, glucose and triglyceride levels were significantly higher and high-density lipoprotein cholesterol (HDL-C) was lower in EBMI-MetS women compared to NBMI ones. Insulin, C-peptide, resistin, adipsin, GIP, leptin, IL-6, FGF21 and PAI-1 levels were significantly higher and ghrelin and IGFBP-1 lower in EBMI-MetS women as compared to NBMI ones. Spearman's correlation of pooled data showed a significant positive correlation between abdominal perimeter and WHR and C-peptide, insulin, adipsin, resistin, leptin, PAI-1 and FGF21 and a negative correlation with IGFBP-1 levels. Total CS-10 scores and hot flush intensity did not differ between studied groups, yet positively correlated with anthropometric values but not with studied analytes. CONCLUSION Perimenopausal women with EBMI and the MetS showed an altered metabolic profile, but no differences in menopausal symptoms which also did not correlate with changes in studied biomarkers.

Saberi, Z, Gorji, N, Memariani, Z, Moeini, R, Shirafkan, H, Amiri, M
Phytotherapy research : PTR. 2020;(12):3359-3366
Abstract
The tendency to use herbs to manage menopausal symptoms has increased in recent years. The purpose of this study was to evaluate the effect of Silybum marianum (L.) compared with placebo in women with hot flashes. Eighty women were randomly allocated into two equal groups (S. marianum extract [400 mg/d] or placebo capsules). Hot flashes frequency and severity were evaluated in 12 weeks with the Greene Climacteric Scale (GCS) and the Hot Flash Related Daily Interference Scale (HFRDIS). The data were analyzed in SPSS software using t-test, Mann-Whitney, chi-square test and repeated measure analysis. Hot flashes frequency and severity decreased from 4.32 ± 0.20/day to 1.31 ± 0.15/day and from 5.25 ± 0.22 to 1.62 ± 0.08, respectively, during the study in test group (p < .001) which were significantly better than effects of placebo in all steps of study (p < .001). Significant decreases in GCS and HFRDIS scores were also detected in S. marianum group compared with placebo after 4, 8 and 12 weeks (p < .001). The results showed that S. marianum can decrease frequency and severity of hot flashes significantly. Considering the safety and high consumption of this herbal medicine worldwide, its use in women with menopausal symptoms can be helpful.

Effects of Chlorogenic Acids on Menopausal Symptoms in Healthy Women: A Randomized, Placebo-Controlled, Double-Blind, Parallel-Group Trial.
Enokuchi, Y, Suzuki, A, Yamaguchi, T, Ochiai, R, Terauchi, M, Kataoka, K
Nutrients. 2020;(12)
Abstract
A reduction in estrogen levels in the perimenopausal and postmenopausal periods causes various symptoms in women, such as hot flushes, sweats, depression, anxiety, and insomnia. Chlorogenic acids (CGAs), which are phenolic compounds widely present in plants such as coffee beans, have various physiological functions. However, the effects of CGAs on menopausal symptoms are unknown. To examine the effects of CGAs on menopausal symptoms, especially hot flushes, a randomized, placebo-controlled, double-blind, parallel-group trial was conducted in healthy women. Eighty-two subjects were randomized and assigned to receive CGAs (270 mg) tablets or the placebo for 4 weeks. After 4 weeks of intake, the number of hot flushes, the severity of hot flushes during sleep, and the severity of daytime sweats decreased significantly in the CGA group compared to the placebo group. The modified Kupperman index for menopausal symptoms decreased significantly after 2 weeks in the CGA group compared to the placebo group. Adverse effects caused by CGAs were not observed. The results show that continuous intake of CGAs resulted in improvements in menopausal symptoms, especially hot flushes, in healthy women.

[Topical hormonal treatment in anti-aging of the skin].
Bayerl, C
Der Hautarzt; Zeitschrift fur Dermatologie, Venerologie, und verwandte Gebiete. 2020;(10):786-790
Abstract
Topical hormonal treatment allows anti-aging of the skin when used during and after the menopause without an increase in the blood level of hormones. Natural hormones are only prescribed by medical doctors. In controlled clinical studies versus placebo and application for months, an increase in skin quality parameters, reduction of dryness, increase of glycosaminoglycanes, increase in elastic fibers und increase of collagen precursers and collagen fibers on the mRNA and protein level could be shown, the latter proven by biopsies. Skin with dramatic sun-damage does not respond to this treatment option. Patients with melasma or seborrhoe should not be treated with hormonal topical preparations. Compared to the natural hormones, phytotherapeutics do not bind to hormone receptors in relevant levels. Growth hormones should not be used in anti-aging treatment due to a potential carcinogenic effect.

Reproductive health in women with type 2 diabetes mellitus.
Creţu, D, Cernea, S, Onea, CR, Pop, RM
Hormones (Athens, Greece). 2020;(3):291-300
Abstract
As type 2 diabetes mellitus (T2DM) reaches epidemic proportions in the developed world and the age at diagnosis decreases, more women of reproductive age are being affected. In this article, we provide a synoptic view on potential mechanisms and relevant factors underlying menstrual cycle disorders and fertility issues in women with T2DM. The article discusses the function of the hypothalamic-pituitary-ovarian (HPO) axis, the central role of the hypothalamus in the homeostasis of this system, the central modulators of the axis, and the peripheral metabolic signals involved in neuroendocrine control of reproduction. The available literature on the relationship between T2DM and the female reproductive lifespan, menstrual cycle disorders, fertility issues, and gestational health in women with T2DM are also discussed. The data so far indicate that there is a "U-shaped" relationship between menarche, menopause, and T2DM, both early and late menarche/menopause being risk factors for T2DM. Hyperglycemia and its consequences may be responsible for the effects of T2DM on reproductive health in women, but the exact mechanisms are not as yet fully understood; thus, more studies are needed in order to identify factors causing disruption of the HPO axis.

Molecular human reproduction. 2020;(12):894-905
Abstract
Commercial hMG drugs are marketed for the treatment of infertility and consist of highly purified hormones acting on receptors expressed in target gonadal cells. Menopur® and Meriofert® are combined preparation of FSH and hCG and are compared in vitro herein. To this purpose, the molecular composition of the two drugs was analyzed by immunoassay. The formation of FSH receptor and LH/hCG receptor (FSHR; LHCGR) heteromer, intracellular Ca2+ and cAMP activation, β-arrestin 2 recruitment and the synthesis of progesterone and estradiol were evaluated in transfected HEK293 and human primary granulosa lutein cells treated by drugs administered within the pg-mg/ml concentration range. Molecular characterization revealed that Meriofert® has a higher FSH:hCG ratio than Menopur® which, in turn, displays the presence of LH molecules. While both drugs induced similar FSHR-LHCGR heteromeric formations and intracellular Ca2+ increase, Meriofert® had a higher potency than Menopur® in inducing a cAMP increase. Moreover, Meriofert® revealed a higher potency than Menopur® in recruiting β-arrestin 2, likely due to different FSH content modulating the tridimensional structure of FSHR-LHCGR-β-arrestin 2 complexes, as evidenced by a decrease in bioluminescence resonance energy transfer signal. This drug-specific activation of intracellular signaling pathways is consistent with the molecular composition of these preparations and impacts downstream progesterone and estradiol production, with Menopur® more potent than Meriofert® in inducing the synthesis of both the steroids. These findings are suggestive of distinct in-vivo activities of these preparations, but require cautious interpretation and further validation from clinical studies.

Fait, T, Sailer, M, Regidor, PA
Gynecological endocrinology : the official journal of the International Society of Gynecological Endocrinology. 2019;(4):360-363
Abstract
Safety concerns or contraindications to the use of hormones have resulted in a rise of the use of herbal medicinal products for the management of menopausal symptoms. The pollen extract Sérélys® represents, due to its ingredients and mode of action, a new and innovative alternative for the management of these symptoms. The aim of the present study was to demonstrate the efficacy and safety of Sérélys®. A prospective, open, observational, and multicentre study was performed on 104 menopausal women. The patients received over 3 months the pollen extract Sérélys® containing the extracts PI82 and GC Fem in a dosage of twice 160 mg extract and 5 mg vitamin E. Using a validated menopausal rating score, the improvement of menopausal symptoms was recorded. A significant decrease of different menopausal symptoms was observed between the starting point of the study and after 12 weeks (p < .0001). Hot flashes were reduced by 48.5%, sleep disturbance by 50.1%, depressive mood by 51.2%, irritability by 47.9%, fatigue by 47.8%, vaginal dryness by 39.63% and muscles and joint pain by 27.4%. The pollen extract Sérélys® reduced significant menopausal symptoms showing a very low side effect profile.

Acupuncture or phy(F)itoestrogens vs. (E)strogen plus progestin on menopausal symptoms. A randomized study.
Palma, F, Fontanesi, F, Facchinetti, F, Cagnacci, A
Gynecological endocrinology : the official journal of the International Society of Gynecological Endocrinology. 2019;(11):995-998
Abstract
The effect of acupuncture and phytoestrogens on climacteric symptoms was compared to the effect of hormone therapy (HT) with estrogen plus progestin. A total of 75 postmenopausal women with hot flushes were randomized to receive for 3 months conjugated estrogens/medroxyprogesterone acetate (0.30 mg/1.5 mg/d), acupuncture weekly or soy isoflavones (75 mg/2/d). Evaluations were performed prior to, at the end, and 3 months after treatments. Main outcomes were modification of the Greene's climacteric scale and menopause quality of life (MenQoL). The Greene's score significantly declined (p < .05) during HT (-5.6 ± 3.1), acupuncture (-6.9 ± 4.5) and phytostrogens (-3.4 ± 4.3) (p < .05 vs. HT). Mean Greene's vasomotor sub-score declined less during phytoestrogens than HT (-0.8 ± 2.0 vs. -2.0 ± 1.9; p < .05) and a ≥ 80% reduction was observed in 17.4% of women on phytoestrogens (p < .05 vs. HT), 44% of women on HT, and 41.7% of women on acupuncture. MenQoL score improved similarly (p < .05) during HT (-1.4 ± 1.3), acupuncture (-1.7 ± 1.0) and phytoestrogens (-1.0 ± 1.3). Three months after treatment end, benefits on MenQoL were conserved more following acupuncture than HT (p < .006). The present data indicate that acupuncture, and in lesser extent phytoestrogens, can be effective therapies for climacteric symptoms. Trial registration: EudraCT Number 2008-006053-4.
