Abstract
BACKGROUND The association between reproductive lifespan and depression in older women is unclear. We conducted this analysis to explore whether a shorter reproductive lifespan is associated with higher odds of depression, while also considering the age at menarche and age at menopause. METHODS This observational study used data from the National Health and Nutrition Examination Survey (NHANES), which was conducted between 2005 and 2018. Reproductive lifespan was defined as years from age at menarche to age at menopause. Depression was assessed using the Patient Health Questionnaire-9 (PHQ-9). Multivariable logistic regression models were used to explore the relationship between the association of reproductive life span, age at menarche and age at menopause with the incidence of depression. RESULTS Totally, 2947 patients aged 60 and above were enrolled in the trial, with 241 individuals (8.18 %) diagnosed with depression. Higher odds of depression were found to be significantly correlated with a shorter reproductive lifespan [Odds Ratio (OR) = 0.95, 95 % Confidence interval (CI) = 0.92-0.98] or an earlier ager at menopause (OR = 0.95, 95 % CI = 0.92-0.99), according to the results of multivariable logistic regression analysis after full adjustment. Subgroup analysis and interaction tests indicated a similar association. LIMITATIONS The cross-sectional study could not yield any conclusions regarding causality. CONCLUSION In this large cross-sectional study, our result suggested that populations with a shorter reproductive lifespan or an earlier age at menopause were significantly more likely to have depressive symptoms in older U.S. women. Further large-scale prospective studies are warranted for a comprehensive analysis of the role of the reproductive lifespan and age at menopause in depression.

Abstract
OBJECTIVES To determine the association between serum vitamin D levels and age at menopause and reproductive lifespan in a group of US postmenopausal women. STUDY DESIGN Data from 6,326 postmenopausal US women in the National Health and Nutrition Examination Survey (NHANES) database 2001-2018 were obtained. Weighted multinomial logistic regression models were used to obtain odds ratios (OR) and 95% confidence intervals (CI). Statistical analyzes were performed using SAS (version 9.4; SAS Institute), and complex survey designs were considered. RESULTS Vitamin D deficiency was associated with a higher likelihood of early menopause (OR = 1.34, 95% CI: 1.15, 1.58; p = 0.008) and lower odds of late menopause (OR = 0.79, 95% CI: 0.52, 0.95) in the unadjusted model but not in the adjusted model. Lower vitamin D levels were associated with a higher risk of a shorter reproductive lifespan. The strongest association was seen in the first tertile of vitamin D deficiency (OR = 1.54; 95% CI: 1:29-1:83). After adjustment, the associations were somewhat weakened but remained statistically significant. CONCLUSIONS The results of this study suggest that vitamin D deficiency and inadequacy might be associated with earlier age at menopause. It may also reduce the reproductive lifespan in women. Given the cross-sectional nature of the NHANES dataset, these results should be interpreted with caution due to temporality bias. Menopausal age is a multifactorial phenomenon, and the identification of factors and their interactions should be evaluated in future studies.

Abstract
Cadmium and lead are known to interfere with the endocrine function. Thus, hormonally regulated processes such as menarche, menopause and pregnancy are likely influenced by chronic exposure to these metals. In US post-menopausal women, who already completed their reproductive lifespan, we evaluated the association between blood cadmium and lead levels with self-reported reproductive lifespan and personal history of pregnancy loss. We selected 5317 post-menopausal women participating in the National Health and Nutrition Examination Survey (NHANES), 1999-2018. Blood cadmium and lead levels were measured by inductively coupled plasma mass spectrometry. Reproductive lifespan was defined as the number of years between self-reported age at menarche and menopause. Personal history of pregnancy loss was defined as number of self-reported pregnancy losses out of the self-reported number of pregnancies. The fully adjusted mean difference in reproductive lifespan (95% confidence interval [CI]) comparing the 80th to the 20th percentiles of blood cadmium and lead distributions was, respectively, 0.50 (0.10, 0.91) and 0.72 (0.41, 1.03) years. Ever smoker showed stronger association of blood lead with reproductive lifespan. For self-reported pregnancy loss, the corresponding fully adjusted relative prevalence (95% CI) was 1.10 (0.93, 1.31) for cadmium and 1.10 (1.00, 1.21) for lead, and remained similar after additional adjustment for reproductive lifespan. In never smokers, the relative prevalence was 1.07 (1.04, 1.11) and 1.16 (1.05, 1.28) for blood cadmium and lead, respectively. These findings suggest that blood cadmium and lead exposures increase reproductive lifespan and prevalence of pregnancy loss in the general population. Additional studies are needed to improve the understanding of mechanisms and prevention potential of metals-related pregnancy outcomes.

Abstract
Some reproductive factors are found to be associated with metabolic outcomes in women; however, little is known about reproductive lifespan characteristics and the mutual effect of age at menarche and age at menopause on cardiovascular risk. This systematic review evaluated reproductive lifespan characteristics and describes the mutual effect of age at menarche and age at menopause on the risk of type 2 diabetes (T2DM) and hypertension at midlife. PubMed, EMBASE, and Web of Science were screened for studies published up to September 1, 2020. The individual effect estimates were reviewed and synthesized without meta-analysis due to methodological and clinical or conceptual diversity in reported studies. Of the 3033 identified studies, 20 were included in the final synthesis: 6 reported reproductive life span; 12 reported age at menarche, and 7 reported age at menopause. Synthesis of two cohorts, with a median follow-up of 9-11 years, showed that a shorter reproductive lifespan was positively associated with T2DM, yielding 6-15% higher risk of T2DM for a one-year decrease in reproductive lifespan. A few studies also demonstrated that women who experienced early menarche (four of six studies) and early menopause (two of five studies) were positively associated with risk of T2DM. The association between reproductive lifespan and hypertension was unclear due to the limited availability of studies. Our findings suggest that a shorter reproductive lifespan is associated with T2DM risk in postmenopausal women, especially those with early menarche and early menopause. Large cohort studies are needed to assess the association between reproductive lifespan and incident hypertension in midlife.

Abstract
Hypothyroidism and hyperthyroidism are observationally associated with sex hormone concentrations and sexual dysfunction, but causality is unclear. We investigated whether TSH, fT4, hypo- and hyperthyroidism are causally associated with sex hormones and sexual function. We used publicly available summary statistics from genome-wide association studies on TSH and fT4 and hypo- and hyperthyroidism from the ThyroidOmics Consortium (N ≤ 54,288). Outcomes from UK Biobank (women ≤ 194,174/men ≤ 167,020) and ReproGen (women ≤ 252,514) were sex hormones (sex hormone binding globulin [SHBG], testosterone, estradiol, free androgen index [FAI]) and sexual function (ovulatory function in women: duration of menstrual period, age at menarche and menopause, reproductive lifespan, and erectile dysfunction in men). We performed two-sample Mendelian randomization (MR) analyses on summary level, and unweighted genetic risk score (GRS) analysis on individual level data. One SD increase in TSH was associated with a 1.332 nmol/L lower (95% CI: - 0.717,- 1.946; p = 2 × 10-5) SHBG and a 0.103 nmol/l lower (- 0.051,V0.154; p = 9 × 10-5) testosterone in two-sample MR, supported by the GRS approach. Genetic predisposition to hypothyroidism was associated with decreased and genetic predisposition to hyperthyroidism with increased SHBG and testosterone in both approaches. The GRS for fT4 was associated with increased testosterone and estradiol in women only. The GRS for TSH and hypothyroidism were associated with increased and the GRS for hyperthyroidism with decreased FAI in men only. While genetically predicted thyroid function was associated with sex hormones, we found no association with sexual function.

Abstract
BACKGROUND To examine the relationship between the length of oestrogen exposure and risk of incident stroke. Also, the additive value of each model was compared for assessing oestrogen exposure and stroke risk in postmenopausal women. STUDY DESIGN AND SETTING Prospective study of 5632 post-menopausal women without a prior history of stroke from 1996 through 2016 in Australian Longitudinal Study on Women's Health. Data on surrogate measures of oestrogen exposure were used to derive five indices of oestrogen exposure including reproductive lifespan (RLS) (age at menopause-age at menarche), endogenous oestrogen and total oestrogen exposure (which included menopausal hormone therapy (MHT use)). The relationships between the length of oestrogen exposure (quartiles) and incident stroke events were examined using multivariable adjusted Cox proportional hazard regression and their predictive accuracy were compared using area under the Receiver Operating Characteristic Curve. RESULTS The mean (SD) for RLS was 37.9(4.3) years. A shorter RLS (≤34 years) was associated with a higher risk of incident stroke after adjustment (HR: 1.85, 95%CI: 1.08, 3.15), compared with 38-40 years. There was 7% decrease in risk of stroke per 1-year increase in RLS (HR: 0.93, 95%CI: 0.89, 0.97). Even though the combination of endogenous oestrogen and exogenous hormones aimed to provide more accurate length of oestrogen exposure, the results showed that each model had similar goodness of fit and did not improve the model of just using RLS as a predictor of incident stroke. CONCLUSIONS A shorter RLS (≤34 years) was associated with higher risk of incident stroke compared to medium RLS. Endogenous oestrogen and of total oestrogen exposure (which included MHT use) did not improve the model of just using RLS as a predictor of incident stroke.

Abstract
Growth hormone receptor knockout mice (GHRKO) have reduced body size and increased insulin sensitivity. These mice are known for having extended lifespan, healthspan and female reproductive longevity. Seventeen α-estradiol (17α-E2) is reported to increase insulin sensitivity and extend lifespan in male mice, with less robust effects in female mice. The aim of this study was to evaluate the ovarian reserve in wild type and GHRKO mice treated with 17α-E2. The mice were divided into four groups, GHRKO mice receiving a standard chow diet, GHRKO mice treated 17α-E2, wild type mice receiving a standard chow diet and WT mice treated with 17α-E2. 17α-E2 was provided in the diet for four months. IGF1 plasma concentrations and changes in body weight were assessed. Histological slides were prepared from the ovaries and the number of follicles was counted. GHRKO mice receiving the control diet had a greater number of primordial follicles and lower numbers of primary follicles compared to the other groups (p < 0.05). 17α-E2 treatment decreased the number of primordial follicles in GHRKO mice (p < 0.05), however had no effect in wild type mice. Treatment with 17α-E2 had no significant effect on the change in body weight during the experiment (p = 0.75). Plasma IGF1 concentrations were significantly lower in GHRKO mice as compared to wild type. In conclusion, we found that GHRKO mice displayed lesser primordial follicle activation as compared to wild type mice, but this phenotype was reversed by 17α-E2 administration, suggesting that ovarian aging is increased by 17α-E2 in long-living mice with extended reproductive longevity.

Abstract
The reproductive life span in women starts at puberty and ends at menopause, following the exhaustion of the follicle stockpile termed the ovarian reserve. Increasing data from experimental animal models and epidemiological studies indicate that exposure to a number of ubiquitously distributed reproductively toxic environmental chemicals (RTECs) can contribute to earlier menopause and even premature ovarian failure. However, the causative relationship between environmental chemical exposure and earlier menopause in women remains poorly understood. The present work, is an attempt to review the current evidence regarding the effects of RTECs on the main ovarian activities in mammals, focusing on how such compounds can affect the ovarian reserve at any stages of ovarian development. We found that in rodents, strong evidence exists that in utero, neonatal, prepubescent and even adult exposure to RTECs leads to impaired functioning of the ovary and a shortening of the reproductive lifespan. Regarding human, data from cross-sectional surveys suggest that human exposure to certain environmental chemicals can compromise a woman's reproductive health and in some cases, correlate with earlier menopause. In conclusion, evidences exist that exposure to RTECs can compromise a woman's reproductive health. However, human exposures may date back to the developmental stage, while the adverse effects are usually diagnosed decades later, thus making it difficult to determine the association between RTECs exposure and human reproductive health. Therefore, epidemiological surveys and more experimental investigation on humans, or alternatively primates, are needed to determine the direct and indirect effects caused by RTECs exposure on the ovary function, and to characterize their action mechanisms.

Abstract
OBJECTIVES The parent-child relationship is critical for human development, yet little is known about its association with offsprings' reproductive health outside the context of abuse and neglect. We investigated whether childhood experiences of poor-quality parenting (characterized as decreased parental care and increased parental overprotection) are associated with women's reproductive timing and lifespan. STUDY DESIGN Observational study of 2383 women aged 55-89 years in 2007 from the English Longitudinal Study of Ageing (ELSA). Multinomial logistic regression models were estimated. MAIN OUTCOME MEASURES Self-reported ages at menarche and menopause and duration of reproductive lifespan. RESULTS Increasing maternal and paternal overprotection were associated with later menarche (≥16 years) after adjustment for age and childhood socioeconomic position (relative risk ratio (RRR) 1.11, 95% CI 1.02-1.21 and 1.11, 95% CI 1.01-1.21, respectively, per unit increase in the predictor). Increasing parental overprotection and decreasing paternal care were associated with earlier menarche (≤10 years). However, these associations were marginally non-significant. Maternal and paternal overprotection were also inversely associated with age at natural menopause after adjustment for age, childhood socioeconomic position and age at menarche (p value for linear trend = 0.041 and 0.004, respectively). Further, increasing paternal overprotection was associated with a shorter reproductive lifespan (≤33 years) (RRR 1.09 (1.01-1.18), per unit increase in the predictor) after adjustment for age and childhood socioeconomic position. Adjustment for additional childhood and adult factors did not explain these associations. CONCLUSIONS Women who experienced poor-quality parenting in childhood, especially increased levels of parental overprotection, might be at increased risk of an unfavourable reproductive health profile that is characterized by late or early menarche, premature menopause and a shorter reproductive lifespan.

Abstract
Studies addressing breast cancer risk factors have been looking at trends relative to age at menarche and menopause. These studies point to a downward trend of age at menarche and an upward trend for age at menopause, meaning an increase of a woman's reproductive lifespan cycle. In addition to studying the effect of the year of birth on the expectation of age at menarche and a woman's reproductive lifespan, it is important to understand how a woman's cohort affects the correlation between these two variables. Since the behavior of age at menarche and menopause may vary with the geographic location of a woman's residence, the spatial effect of the municipality where a woman resides needs to be considered. Thus, a Bayesian multivariate structured additive distributional regression model is proposed in order to analyze how a woman's municipality and year of birth affects a woman's age of menarche, her lifespan cycle, and the correlation of the two. The data consists of 212,517 postmenopausal women, born between 1920 and 1965, who attended the breast cancer screening program in the central region of Portugal.

Abstract
BACKGROUND Sex and blood level of sex hormones play a key role not only in the susceptibility to develop Parkinson's disease (PD) but also influence the natural course of the disease. The aim of this study was to compare reproductive lifespan events in females affected with PD and in "non-parkinsonian" age matched subjects and to evaluate whether the whole life endogenous oestrogen level is associated with variables describing the course of the disease. MATERIALS AND METHODS Reproductive lifespan, age at menarche, age at menopause, gynaecological interventions and parity were compared in 76 women with idiopathic PD and in the age-adjusted control group of 74 subjects. Affected women underwent neurological and psychological assessment. Data were analysed using Mann-Whitney U Test and Spearman Rank Correlation Test. RESULTS Women affected with PD had a shorter reproductive lifespan and experienced final menstruation earlier than the control group. Early menopause was reported by 24% of the patients and only by 16% of the control subjects. Parkinsonian women reported more commonly the history of surgical menopause. Duration of reproductive lifespan, age at menopause and the type of menopause influenced both motor and cognitive functioning of patients. CONCLUSIONS There may be a relationship between the lifetime average endogenous oestrogen level and the susceptibility to develop PD. Longer reproductive lifespan resulting in higher "whole life" female sex steroids concentrations may exert a protective effect on central nervous system, resulting in milder course of the disease.

Abstract
This study explores the role of ovarian hormones in the phenotypic shaping of peripheral T-cell pool over the reproductive lifespan of rats. For this purpose, 2-month-old prepubertally ovariectomised (Ox) rats, showing oestrogen and progesterone deficiency, and 11-month-old Ox rats, exhibiting only progesterone deficiency, were examined for thymus output, and cellularity and composition of major TCRαβ+ peripheral blood lymphocyte (PBL) and splenocyte subsets. Although ovariectomy increased thymic output in both 2- and 11-month-old rats, the count of both CD4+ and CD8+ PBLs and splenocytes increased only in the former. In the blood and spleen of 11-month-old Ox rats only the count of CD8+ cells increased. Although ovariectomy affected the total CD4+ count in none of the examined compartments from the 11-month-old rats, it increased CD4+FoxP3+ PBL and splenocyte relative proportions over those in the age-matched controls. The age-related differences in the cellularity and the major subset composition in Ox rats were linked to the differences in the ovarian steroid hormone levels registered in 2- and 11-month-old rats. The administration of progesterone to Ox rats during the seven days before the sacrificing confirmed contribution of this hormone deficiency to the ovariectomy-induced changes in the TCRαβ+ PBL and splenocyte pool from 11-month-old rats. The expansion of the CD8+ splenocyte subset in the 11-month-old Ox rats reflected increases in cellularity of memory and, particularly, naïve cells. This was due to greater thymic output of CD8+ cells and homeostatic proliferation than apoptosis in 11-month-old Ox rats when compared with age-matched sham-Ox control rats. The homeostatic changes within CD8+ splenocyte pool from 11-month-old Ox rats, most likely, reflected the enhanced splenic IL-7 and TGF-β mRNA expression. Overall, in adult female rats, circulating oestrogen and progesterone provide maintenance of T-cell counts, a diversity of T-cell repertoire, and the main T-cell subset composition in the periphery. Progesterone deficiency affects mainly the CD8+ lymphocyte compartment through increasing thymic CD8+ cell export and upsetting homeostatic regulation within the CD8+ splenocyte pool. These alterations were reversible through progesterone supplementation.
