Heliyon 2024; 10:e35088. [PMID: 39170162 PMCID: PMC11336435 DOI: 10.1016/j.heliyon.2024.e35088] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2023] [Revised: 07/16/2024] [Accepted: 07/23/2024] [Indexed: 08/23/2024] Open
Abstract
Luteal phase defect (LPD) is a common female reproductive endocrine defect,which is associated not only with certain diseases but also with the menstrual cycle and fertility in women. With the development of assisted reproductive technology (ART) in recent years, the incidence of luteal phase defect is high among patients using assisted reproductive technology. The aim of this study was to evaluate worldwide research on luteal phase defects using bibliometric analysis. A total of 631 documents related to the study of luteal phase defect were identified over the last 52 years. The current status and trend of globalization can be comprehended by analyzing the annual number of publications, institutions, authors, countries and regions of corresponding authors, journals, influential luteal phase defect publications (which were highly cited), highly cited references in luteal phase defect publications (cocitation analysis) and keywords. The study results provide a comprehensive overview of the development of scientific literature and are of great significance for the future development of the field,especially infertility and early pregnancy loss.

Abstract
PURPOSE The aim of this study was to determine the effects of different menopausal hormone therapy regimens on body composition in healthy postmenopausal Chinese women. MATERIALS AND METHODS One hundred and twenty-three healthy postmenopausal Chinese women were randomly assigned to either group A (0.625 mg conjugated equine estrogens [CEE] plus 100 mg micronized progesterone [MP]), group B (0.3 mg CEE plus 100 mg MP), or group C (0.625 mg CEE plus 10 mg dydrogesterone). Body composition was assessed by dual-energy X-ray absorptiometry. RESULTS One hundred and two women completed the trial at 1 year. A small but significant gain in lean body mass (619 ± 1019 g, p = 0.002) and a decrease of fat mass in all separate regions was observed in group A. A significant shift from gynoid to android fat distribution was observed in group B and group C (android/gynoid fat percentage ratios increased by 0.06 ± 0.08, p = 0.000 and 0.03 ± 0.08, p = 0.018, respectively), whereas no significant change was observed in group A (0.02 ± 0.06, p = 0.103). CONCLUSIONS In healthy postmenopausal Chinese women, 0.625 mg of CEE combined with 100 mg of MP was associated with a more favorable fat distribution compared with 0.3 mg CEE plus 100 mg MP or 0.625 mg CEE plus 10 mg dydrogesterone.

Abstract
This observational study was conducted in healthy premenopausal women, who presented themselves for contraceptive advice at the outpatient Family Planning Clinics of the Department of Obstetrics and Gynecology of the University of Cagliari, Hospital-University of Cagliari (Italy). After a screening period of three menstrual cycles, 48 women without contraindications to estroprogestin contraceptives (OCs) were included in the study. The primary purposes of the study were to evaluate whether a 12-month-treatment with the combined OC containing micronized estradiol (1.5 mg, E2) plus nomegestrol acetate (2.5 mg, NOMAC) (E2/NOMAC) interfere on anthropometric indices (AI), body composition (BC) and psychological status (PS). In subjects with dysmenorrhea (#36), its intensity was evaluated using the visuo analogic scale (VAS), both before and during the 12-month-treatment with E2/NOMAC. E2/NOMAC did not modify neither AI nor BC in the 40 subjects who concluded the study. The PS and the VAS of dysmenorrhea were significantly (p < 0.0001) improved from the first cycle of treatment and throughout the E2/NOMAC treatment in comparison with basal values. The study suggests that E2/NOMAC is devoid of negative effects on AI and BC, with additional benefits on PS and dysmenorrhea.

Abstract
In the menopausal transition (MT), combined oral contraceptive (COC) should be chosen accordingly to its neutrality on liver metabolism and to its ability to counter the increase of fat mass (FM) that occurs in this reproductive period of life. This prospective multi-centric observational study was conducted on 36 women in their MT at the Universities of Cagliari, Modena and Naples. The body weight (BW), the Body Mass Index (BMI), the waist to hip ratio (WHR), the measurement of body composition (BC) with the Multi-frequency Bioelectrical Impedance (MF-BIA) were performed before, at the 6th and at the 12th month of the study in which a group of women (control group; N.18) did not assume COC, whereas the other 18 women assumed the four-phasic COC containing estradiol valerate (EV) associated with dienogest (EV/DNG group). In comparison to controls in the EV/DNG group, a significant decrease (p < 0.05) of BW (58.8 ± 7.6 to 57.3 ± 7.0), BMI (24.1 ± 2.7 to 23.5 ± 2.8), WHR (0.82 ± 0.052 to 0.79 ± 0.048) and FM (17.7 ± 5.4 to 16.4 ± 5.6) was observed. In controls, FM significantly increased (17.0 ± 11 to 17.7 ± 2.7; p < 0.05). In conclusion, these results suggest that the anti-androgenic and progestinic activities of DNG associated with a weak estrogenic activity of EV, is a contraceptive method capable of counteracting the negative changes of BC occurring in the MT.

Abstract
OBJECTIVE The effect on body composition and in particular on fat mass (FM) of 12 months' use of a desogestrel (DSG)-only contraceptive pill or the levonorgestrel-releasing intrauterine system (LNG-IUS) was evaluated in women in the perimenopause. METHODS An observational study comprised 102 perimenopausal women: 42 received a 75 μg DSG pill, 34 received the 52 mg LNG-IUS, and 26 received no treatment. Body composition, body weight and resting metabolic rate (RMR) were evaluated at baseline and again after 12 months. RESULTS FM did not change in the control group (- 0.5 ± 1.6%) but significantly increased in the LNG-IUS group (+ 1.1 ± 2.9%; p = 0.02 vs. controls) and in the DSG group (+ 2.8 ± 3.5%; p = 0.0001 vs. controls; p = 0.02 vs. LNG-IUS). Women treated with DSG or the LNG-IUS showed a non-significant increase in body weight, body mass index and waist circumference. RMR did not significantly vary in the control group (- 3.8 ± 292.9 kJ/ 24 h) and tended to decrease but not significantly in the LNG-IUS (115.5 ± 531.8 kJ/ 24 h) and DSG groups (305.9 ± 556.9 kJ/24 h). CONCLUSIONS The results of this preliminary study seem to indicate that in perimenopausal women continuous use of the DSG-only pill and to a lesser extent the LNG-IUS may favour FM accumulation.

Abstract
The study was performed to compare the clinical effect of a hormone replacement therapy (HRT) with two different progestins. Postmenopausal women (PMW) with climacteric symptoms (CS) randomly received for 12 months orally, either placebo (n = 20), 1 mg estradiol (E) plus 0.5 mg noretisterone acetate (NETA; n = 40), or 2 mg drospirenone (DRSP; n = 40), a testosterone- and spironolactone-derived molecule, respectively. Weight (W) declined only during E/DRSP (p < 0.04 versus placebo). Fat mass (FM) decreased, similarly, during E/NETA and E/DRSP. Intracellular water (ICW) did not change, while extracellular water (ECW) decreased during E/DRSP (p < 0.0001) (p < 0.002 versus E/NETA). During E/NETA and E/DRSP, similar decreases were observed for insulin resistance (IR) by the homeostatic model assessment for IR (HOMA-IR) (p < 0.0001 versus placebo for both), systolic (p < 0.04 versus placebo for both) and diastolic (p < 0.002) blood pressure (BP). Lipids did not change. In comparison to placebo CS, by the Kupperman Index (KI), significantly declined (p < 0.0001) during E/NETA or E/DRSP. Menopause-specific Quality of Life (MENQoL) significantly declined versus placebo (p < 0.04) during both E/NETA and E/DRSP. In conclusion, differences between the two progestins are mainly limited to body composition (BC), where the addition of DRSP decreases ECW and body W (BW).

Abstract
AIM To observe the influence on metabolism and body composition of two oral contraceptives containing non-androgenic progestins in association with estradiol or ethinyl estradiol (EE). STUDY DESIGN Women on hormonal contraception with estradiol valerate (E2V)/dienogest (DNG) in a quadriphasic regimen (n = 16) or 30 μg EE/2 mg chlormadinone acetate (CMA) (n = 16) in a monophasic regimen were evaluated at the third cycle for modifications in lipoproteins, apoproteins and homeostatic model assessment for insulin resistance (HOMA-IR), and at the sixth cycle for body composition and the markers of bone turnover osteocalcin and C-telopeptide X. RESULTS During E2V/DNG lipoprotein, apoproteins and HOMA-IR remained stable. During EE/CMA, total-cholesterol (p = 0.003), high-density lipoprotein (HDL)-cholesterol (p = 0.001), triglycerides (p = 0.003) Apoprotein-A1 (Apo-A1; p = 0.001) and Apo B (p = 0.04) increased, low-density lipoprotein/HDL (p = 0.039) decreased and total-cholesterol/HDL and Apoprotein-B/Apo-A1 ratio did not vary. HOMA-IR slightly increased from 1.33 ± 0.87 to 1.95 ± 0.88 (p = 0.005). There was a reduction of markers of bone metabolism in both groups with no modification of body composition. CONCLUSIONS Administration of E2V/DNG does not influence lipid and glucose metabolism, while mixed effect are exerted by EE/CMA. Both preparations reduce bone metabolism without influencing short-term effect on body composition.

Abstract
Obesity prevalence is generally higher in women than in men, and there is also a sex difference in body fat distribution. Sex differences in obesity can be explained in part by the influence of gonadal steroids on body composition and appetite; however, behavioural, socio-cultural and chromosomal factors may also play a role. This review, which evolved from the 2008 Stock Conference on sex differences in obesity, summarizes current research and recommendations related to hormonal and neuroendocrine influences on energy balance and fat distribution. A number of important gaps in the research are identified, including a need for more studies on chromosomal sex effects on energy balance, the role of socio-cultural (i.e. gender) factors in obesity and the potential deleterious effects of high-fat diets during pregnancy on the foetus. Furthermore, there is a paucity of clinical trials examining sex-specific approaches and outcomes of obesity treatment (lifestyle-based or pharmacological), and research is urgently needed to determine whether current weight loss programmes, largely developed and tested on women, are appropriate for men. Last, it is important that both animal and clinical research on obesity be designed and analysed in such a way that data can be separately examined in both men and women.

Abstract
OBJECTIVE To evaluate modification in body weight and anthropometric indexes in women at the time of menopause. DESIGN Prospective longitudinal study. SETTING Menopause Center at the University Hospital of Modena. PATIENT(S) Women in perimenopause (n = 87), ovariectomized (n = 60), and in postmenopause (n = 182) without and with treatment. INTERVENTION(S) Data were retrieved from the electronic database of the Menopause Center. MAIN OUTCOME MEASURE(S) Modification of weight, body mass index (BMI), waist, hip, and waist-to-hip ratio in 12 months. RESULT(S) Body weight increased in perimenopausal (0.6 +/- 0.1 kg) women, did not vary in postmenopausal (0.2 +/- 0.1 kg) women, and decreased in ovariectomized (-0.5 +/- 0.3 kg) women. Waist increased significantly in perimenopausal (2.3 +/- 0.4 cm) and in postmenopausal (2.0 +/- 0.4 cm) women. In comparison to no treatment, progestin administration (n = 29) decreased body weight (-0.2 +/- 0.5 kg) and hip (-1.1 +/- 0.9 cm) in perimenopausal women, estrogen (E) administration (n = 38) increased body weight (0.8 +/- 0.3 kg) in ovariectomized women, whereas E plus progestin administration (n = 89) did not induce any modification in postmenopausal women. CONCLUSION(S) Present preliminary data indicate that body weight increases in perimenopausal women, decreases in ovariectomized women, and does not increase significantly in naturally postmenopausal women. Estrogens and progestins influence body weight differently, increasing and decreasing it, respectively.

Abstract
OBJECTIVE To delineate a perceived association of estradiol versus estradiol plus norethisterone hormone therapy on the prevalence of colorectal cancer in postmenopausal women. METHODS The Women's Health in the Lund Area (WHILA) project covers 10,766 women aged 50-60 years, living in the Lund area, Sweden. Out of this population, 6908 (64%) women completed questionnaires, underwent physical and laboratory assessments and had self-reported information regarding colorectal cancer. Four hundred and twenty-two (6%) were premenopausal (PM), 3600 (52%) were postmenopausal without hormone therapy (PM0), 2452 (36%) were postmenopausal with combined hormone therapy (PMT-HT) and 364 (5%) were postmenopausal with estrogen monotherapy (PMT-E). RESULTS There were 21 cases of colorectal cancer (0.3%), one in the PM group, 16 in the PM0 group, two in the PMT-HT group and another two in the PMT-E group. Colorectal cancer prevalence was lower in the PMT-HT than in the PM0 group (odds ratio (OR) = 0.18, 95% confidence interval (CI) = 0.04-0.80). However, for the PMT-E group, the OR (95% CI) was 1.02 (0.86-1.20). There was a positive association between low physical activity (p = 0.04), low parity (p = 0.02) and risk of colorectal cancer. CONCLUSION Combined hormone therapy seemed to be associated with a lower risk of colorectal cancer in postmenopausal women in contrast to estrogen monotherapy. Hence the progestin might have a protective role.
