Management of menopause: a view towards prevention.

Women spend approximately one-third of their lives with menopause, which occurs around 50 years of age. It is now appreciated that several important metabolic and cardiovascular disease risks emerge during the menopausal transition. Many important conditions occur 10-15 years after menopause, including weight gain and obesity, metabolic syndrome, diabetes, osteoporosis, arthritis, cardiovascular disease, dementia, and cancer; therefore, the occurrence of menopause heralds an important opportunity to institute preventative strategies.

Workshop on normal reference ranges for estradiol in postmenopausal women, September 2019, Chicago, Illinois.

The North American Menopause Society (NAMS) organized the Workshop on Normal Ranges for Estradiol in Postmenopausal Women from September 23 to 24, 2019, in Chicago, Illinois. The aim of the workshop was to review existing analytical methodologies for measuring estradiol in postmenopausal women and to assess existing data and study cohorts of postmenopausal women for their suitability to establish normal postmenopausal ranges. The anticipated outcome of the workshop was to develop recommendations for establishing normal ranges generated with a standardized and certified assay that could be adopted by clinical and research communities.

Is There Really Increased Cardiovascular Morbidity in Women with Polycystic Ovary Syndrome?

For some time, it has been assumed that women with polycystic ovary syndrome (PCOS) are at increased risk of developing cardiovascular disease (CVD). This has largely been on the basis of having many risk factors, including abnormal lipid profile, insulin resistance, and markers of inflammation. However, despite having these and other risk factors, we argue here, in the view of the authors, that there is no credible evidence that there is greater CVD morbidity in all women with PCOS.

Features of polycystic ovary syndrome (PCOS) in women with functional hypothalamic amenorrhea (FHA) may be reversible with recovery of menstrual function.

Objective: Since features of polycystic ovary syndrome (PCOS) have been found to be prevalent in women with functional hypothalamic amenorrhea (FHA), we wished to determine what happens to these features after recovery of menstrual function in FHA Design: Prospective cohort study. Twenty-eight women with FHA and 30 age-matched ovulatory controls were studied.

Methods: Twenty-eight women with FHA and 30 age-matched ovulatory controls were studied.

Repeated doses of GnRH antagonist at midcycle in artificial frozen embryo transfer cycles may not affect pregnancy outcomes.

No significant differences in outcomes have been found between protocols of endometrial preparation for frozen embryo transfer (FET), though gonadotropin releasing hormone (GnRH) antagonists may have detrimental effects on the endometrium. We conducted a retrospective cohort noninferiority study at a single academic center of women receiving multiple doses of mid-cycle GnRH antagonist (GAnt) to those receiving GnRH agonist (GAg) to determine if there are detrimental effects of GnRH antagonists. 1047 FET cycles were identified, detailed data was available in 840 cycles: 610 GAg and 230 GAnt cycles.

Hormone-replacement therapy: current thinking.

For several decades, the role of hormone-replacement therapy (HRT) has been debated. Early observational data on HRT showed many benefits, including a reduction in coronary heart disease (CHD) and mortality. More recently, randomized trials, including the Women's Health Initiative (WHI), studying mostly women many years after the the onset of menopause, showed no such benefit and, indeed, an increased risk of CHD and breast cancer, which led to an abrupt decrease in the use of HRT.

Back to the future: Hormone replacement therapy as part of a prevention strategy for women at the onset of menopause.

In the late 1980s, several observational studies and meta-analyses suggested that hormone replacement therapy (HRT) was beneficial for prevention of osteoporosis, coronary heart disease, dementia and decreased all-cause mortality. In 1992, the American College of Physicians recommended HRT for prevention of coronary disease. In the late 1990s and early 2000s, several randomized trials in older women suggested coronary harm and that the risks, including breast cancer, outweighed any benefit.

Increased anti-Mullerian hormone levels and ovarian size in a subgroup of women with functional hypothalamic amenorrhea: further identification of the link between polycystic ovary syndrome and functional hypothalamic amenorrhea.

Background: Functional hypothalamic amenorrhea is a disorder characterized by cessation of menstrual cycles in the absence of organic disease. In most patients, it occurs in adult life after a stressful event and may be related to a condition of mild chronic energy deprivation. The endocrine pattern is characterized by low estrogen levels with an absent response to a progestogen challenge test and low-normal gonadotropin levels.

Human embryos commonly form abnormal nuclei during development: a mechanism of DNA damage, embryonic aneuploidy, and developmental arrest.

Study Question: What is the prevalence and developmental significance of morphologic nuclear abnormalities in human preimplantation embryos?

Summary Answer: Nuclear abnormalities are commonly found in human IVF embryos and are associated with DNA damage, aneuploidy, and decreased developmental potential.

What Is Known Already: Early human embryonic development is complicated by genomic errors that occur after fertilization. The appearance of extra-nuclear DNA, which has been observed in IVF, may be a result of such errors.

Chemerin as a marker of body fat and insulin resistance in women with polycystic ovary syndrome.

Adipocytokines may alter normal metabolic function and play an important role in the pathophysiology of polycystic ovary syndrome (PCOS). We prospectively evaluated a cohort of obese and non-obese women with PCOS and non-PCOS controls for both novel (chemerin and omentin-1) and established (leptin and adiponectin) adipokines. Compared with age-matched controls, non-obese women with PCOS had decreased serum omentin-1 (191.

Preliminary evidence that cinnamon improves menstrual cyclicity in women with polycystic ovary syndrome: a randomized controlled trial.

Objective: To determine the effect of cinnamon on menstrual cyclicity and metabolic dysfunction in women with polycystic ovary syndrome (PCOS).

Study Design: In a prospective, placebo controlled, double-blinded randomized trial, 45 women with PCOS were randomized (1:1) to receive cinnamon supplements (1.5 g/d) or placebo for 6 months.

Where are we 10 years after the Women's Health Initiative?

The media attention surrounding the publication of the initial results of WHI in 2002 led to fear and confusion regarding the use of hormonal therapy (HT) after menopause. This led to a dramatic reduction in prescriptions for HT in the United States and around the world. Although in 2002 it was stated that the results pertained to all women receiving HT, subsequent studies from the Women's Health Initiative (WHI) and others clearly showed that younger women and those close to menopause had a very beneficial risk-to-benefit ratio.

Best practices of ASRM and ESHRE: a journey through reproductive medicine.

Background: The American Society for Reproductive Medicine (ASRM) and the European Society of Human Reproduction and Embryology (ESHRE) are the two largest societies in the world whose members comprise the major experts and professionals working in the field of reproductive medicine and embryology. These societies have never before had a joint scientific meeting.

Method(s): A 3-day meeting was planned and took place in March of 2012.

Ovarian adipocytokines are associated with early in vitro human embryo development independent of the action of ovarian insulin.

Purpose: We aimed to characterize the association between levels of serum and follicular fluid (FF) adipocytokines, reflected by the leptin to adiponectin ratio (L:A ratio), and oocyte quality and in vitro embryo development in women undergoing assisted reproduction. We also aimed to assess whether follicular hormonal pathways mediate this interaction.

Methods: We prospectively collected FF from up to four individual preovulatory follicles (n = 76) and fasting sera from women (n = 31) without endocrinopathies undergoing in vitro fertilization (IVF) at a university-based center for assisted reproduction.

A 20-year follow-up of young women with polycystic ovary syndrome.

Objective: To determine whether hormonal, metabolic, and anthropomorphic parameters change over 20 years in women with polycystic ovary syndrome (PCOS).

Methods: One hundred ninety-three women with PCOS, aged 20-25 years, were diagnosed according to Rotterdam criteria, divided into four phenotypes (A-D), and followed at 5-year intervals for 20 years. Androgens, gonadotropins, insulin, glucose, body mass index, waist circumference, and ovarian volume were measured.

Consensus on women's health aspects of polycystic ovary syndrome (PCOS): the Amsterdam ESHRE/ASRM-Sponsored 3rd PCOS Consensus Workshop Group.

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in females, with a high prevalence. The etiology of this heterogeneous condition remains obscure, and its phenotype expression varies. Two widely cited previous ESHRE/ASRM sponsored PCOS consensus workshops focused on diagnosis (published in 2004) and infertility management (published in 2008), respectively.
