Does serum anti-Müllerian hormone (AMH) vary significantly throughout both ovulatory and sporadic anovulatory menstrual cycles in healthy premenopausal women?
Summary Answer
Serum AMH levels vary statistically significantly across the menstrual cycle in both ovulatory and sporadic anovulatory cycles of healthy eumenorrheic women.
What Is Known Already
Studies to date evaluating serum AMH levels throughout the menstrual cycle have conflicting results regarding intra-woman cyclicity. No previous studies have evaluated an association between AMH and sporadic anovulation.
Study Design, Size, Duration
We conducted a prospective cohort study of 259 regularly menstruating women recruited between 2005 and 2007.
Participants/Materials, Setting, Methods
Women aged 18-44 years were followed for one (n = 9) or two (n = 250) menstrual cycles. Anovulatory cycles were defined as any cycle with peak progesterone concentration ≤5 ng/ml and no serum LH peak on the mid or late luteal visits. Serum AMH was measured at up to eight-time points throughout each cycle.
Main Results and the Role of Chance: Geometric mean AMH levels were observed to vary across the menstrual cycle (P < 0.01) with the highest levels observed during the mid-follicular phase at 2.06 ng/ml, decreasing around the time of ovulation to 1.79 ng/ml and increasing thereafter to 1.93 (mid-follicular versus ovulation, P < 0.01; ovulation versus late luteal, P = 0.01; mid-follicular versus late luteal, P = 0.05). Patterns were similar across all age groups and during ovulatory and anovulatory cycles, with higher levels of AMH observed among women with one or more anovulatory cycles (P = 0.03).
Limitations, Reasons for Caution
Ovulatory status was not verified by direct visualization. AMH was analyzed using the original Generation II enzymatically amplified two-site immunoassay, which has been shown to be susceptible to assay interference. Thus, absolute levels should be interpreted with caution, however, patterns and associations remain consistent and any potential bias would be non-differential.
Wider Implications of the Findings
This study demonstrates a significant variation in serum AMH levels across the menstrual cycle regardless of ovulatory status. This variability, although statistically significant, is not large enough to warrant a change in current clinical practice to time AMH measurements to cycle day/phase.

Menstrual cycle is considered the fifth vital sign among women. This study aimed to summarize the menstrual disturbances in different endocrine disorders.
In this narrative review, relevant studies (up to December 2019) were searched based on the MeSH keywords diabetes, polycystic ovary syndrome, Cushing's syndrome, thyroid dysfunction, hyperprolactinemia, menstrual cycle, uterine bleeding, and menstruation. Databases used for searching articles included Google Scholar, Scopus, PubMed, and Web of science for observational, experimental, and review studies. Endocrine disorders trigger the onset of menstrual disturbance across the reproductive lifespan of women. Endocrine glands (pituitary, thyroid, pancreas, adrenal, and ovaries) have a functional role in endocrine regulation of the menstrual cycle. According to available evidence, oligomenorrhea (cycles longer than 35 days) is the most common menstrual disturbance among endocrine disorders (thyrotoxicosis, hypothyroidism, polycystic ovary syndrome, Cushing's syndrome, and diabetes). Complex endocrine pathways play an essential role in a women's menstrual calendar. The menstrual cycle length and amount of bleeding can be indicative of endocrine disorders. Further studies are needed to identify the unknowns about the association between endocrine disorders and the menstrual cycle.

Does use of commonly used over-the-counter (OTC) pain medication affect reproductive hormones and ovulatory function in premenopausal women? Few associations were found between analgesic medication use and reproductive hormones, but use during the follicular phase was associated with decreased odds of sporadic anovulation after adjusting for potential confounders. Analgesic medications are the most commonly used OTC drugs among women, but their potential effects on reproductive function are unclear. STUDY DESIGN, SIZE, The BioCycle Study was a prospective, observational cohort study (2005-2007) which followed 259 women for one (n = 9) or two (n = 250) menstrual cycles. PARTICIPANTS, SETTING, Two hundred and fifty-nine healthy, premenopausal women not using hormonal contraception and living in western New York state. Study visits took place at the University at Buffalo. Main During study participation, 68% (n = 175) of women indicated OTC analgesic use. Among users, 45% used ibuprofen, 33% acetaminophen, 10% aspirin and 10% naproxen. Analgesic use during the follicular phase was associated with decreased odds of sporadic anovulation after adjusting for age, race, body mass index, perceived stress level and alcohol consumption (OR 0.36 [0.17, 0.75]). Results remained unchanged after controlling for potential confounding by indication by adjusting for 'healthy' cycle indicators such as amount of blood loss and menstrual pain during the preceding menstruation. Moreover, luteal progesterone was higher (% difference = 14.0, -1.6-32.1, P = 0.08 adjusted) in cycles with follicular phase analgesic use, but no associations were observed with estradiol, LH or FSH. LIMITATIONS, Self-report daily diaries are not validated measures of medication usage, which could lead to some classification error of medication use. We were also limited in our evaluation of aspirin and naproxen which were used by few women. The observed associations between follicular phase analgesic use and higher progesterone and a lower probability of sporadic anovulation indicate that OTC pain medication use is likely not harmful to reproduction function, and certain medications possibly improve ovulatory function.

Are prospectively assessed dietary factors, including overall diet quality, macronutrients and micronutrients, associated with luteal phase deficiency (LPD) in healthy reproductive aged women with regular menstrual cycles? Mediterranean Diet Score (MDS), fiber and isoflavone intake were positively associated with LPD while selenium was negatively associated with LPD after adjusting for age, percentage body fat and total energy intake. LPD may increase the risk of infertility and early miscarriage. Prior research has shown positive associations between LPD and low energy availability, either through high dietary restraint alone or in conjunction with high energy expenditure via exercise, but few studies with adequate sample sizes have been conducted investigating dietary factors and LPD among healthy, eumenorrheic women. STUDY DESIGN, SIZE, The BioCycle Study (2005-2007) prospectively enrolled 259 women from Western New York state, USA, and followed them for one (n = 9) or two (n = 250) menstrual cycles. PARTICIPANTS/MATERIALS, SETTING, Women aged 18-44 years, with self-reported BMI between 18 and 35 kg/m(2) and cycle lengths between 21 and 35 days, were included in the study. Participants completed baseline questionnaires, four 24-h dietary recalls per cycle and daily diaries capturing vigorous exercise, perceived stress and sleep; they also provided up to eight fasting serum samples during clinic visits timed to specific phases of the menstrual cycle using a fertility monitor. Cycles were included for this analysis if the peak serum luteal progesterone was >1 ng/ml and a urine or serum LH surge was detected. Associations between prospectively assessed diet quality, macronutrients and micronutrients and LPD (defined as luteal duration <10 days) were evaluated using generalized linear models adjusting for age, percentage body fat and total energy intake. MAIN LPD occurred in 41 (8.9%) of the 463 cycles from 246 women in the final analysis. After adjusting for age, percentage body fat and total energy intake, LPD was positively associated with MDS, adjusted odds ratio (aOR): 1.70 (95% confidence interval [CI]: 1.17, 2.48), P = 0.01. In separate macro- and micronutrient adjusted models, increased fiber and isoflavone intake showed modest fiber (per g), 1.10 (95% CI: 0.99, 1.23), P = 0.07; and isoflavones (per 10 mg), 1.38 (95% CI: 0.99, 1.92), P = 0.06. In contrast, selenium (per 10 mcg) was inversely associated with LPD, 0.80 (95% CI: 0.65, 0.97), P = 0.03. Additional adjustments for relevant lifestyle factors including vigorous exercise, perceived stress and sleep did not appreciably alter estimates. LIMITATIONS, The number of LPD cycles was limited, and thus these findings are exploratory. We relied on participant self-report of their medical history to apply exclusion criteria; it is possible that we admitted to the study women with a gynecologic or medical disease who were unaware of their diagnosis. Our study suggests that diet quality may be associated with LPD among healthy eumenorrheic women. As LPD may contribute to infertility and early miscarriage, further research is warranted to elucidate how dietary factors, such as MDS, may influence LPD. The inverse association we found with selenium is supported by previous research and deserves further investigation to determine whether this finding has pathophysiologic and therapeutic implications.

Attention-Deficit/Hyperactivity Disorder (ADHD) in girls and women is under-recognised and under-researched, despite increasing awareness of clinical challenges and unmet needs. This review by the Eunethydis Special Interest Group on Female ADHD, addresses current knowledge and identifies research gaps for future work. Issues in women with ADHD across the lifespan such as late diagnosis, pubertal development, sexual health, hormonal birth control, executive function difficulties, and gynaecological disorders associated with ADHD are highlighted. The review synthesises existing literature and self-reported experiences of women with ADHD to explore the impact of hormonal fluctuations [puberty, menstrual cycle, pregnancy, (peri)menopause] on ADHD symptoms and mood disturbances. It examines the interplay of oestrogen and progesterone with dopaminergic pathways, when periods of lower oestrogen may affect cognition, as well as the manifestation of executive function deficits, and the intersection of ADHD with reproductive health. Hormonal transitions exacerbate ADHD symptoms and mood disturbances, yet pharmacological research and tailored treatments are lacking. Executive function deficits manifest differently in girls and women with ADHD and are influenced by neuropsychological and neurobiological profiles. Diagnostic practices and sociocultural factors contribute to delayed diagnoses, increasing the risk of comorbidities, impaired functioning, and diminished quality of life. Undiagnosed women have increased vulnerability to premenstrual dysphoric disorder, postpartum depression, and cardiovascular disease during perimenopause. Longitudinal, sex-specific studies incorporating hormonal status and lived experience are needed. Individualised interventions should be developed to address the unique needs of girls and women with ADHD. Addressing these gaps will advance more equitable diagnosis, management, and support for girls and women with ADHD, improving outcomes across the female lifespan.
