RESUMEN

Background: Past research on polycystic ovary syndrome (PCOS), a chronic endocrine condition, has focused on the experiences of cisgender women. Aims: The purpose of the present study was to address the knowledge gap about gender-diverse individuals by exploring their lived experiences with PCOS and to better understand if and how their gender identity affected their experience of PCOS. Methods: To explore this, we recruited nine non-binary people and one transgender man with a PCOS diagnosis for qualitative interviews. Results: Three overarching themes emerged: PCOS as a burden, PCOS as an occasion, and PCOS as a benefit. While some aspects of PCOS created an additional burden for our participants, other symptoms such as excess body and facial hair could be empowering and affirming, revealing a positive aspect of this chronic condition. Conclusion: This study is the first to describe the lived experiences of gender-diverse individuals with PCOS, uncovering burdens as well as some benefits. Future research in this population may reveal not only the particulars of what PCOS is like for them but also more generalizable insights into the highly gendered perception and treatment of PCOS.

RESUMEN

Ways in which ovarian hormones affect cognition have been long overlooked despite strong evidence of their effects on the brain. To address this gap, we study performance on a rule-plus-exception category learning task, a complex task that requires careful coordination of core cognitive mechanisms, across the menstrual cycle (N = 171). Results show that the menstrual cycle distinctly affects exception learning in a manner that parallels the typical rise and fall of estradiol across the cycle. Participants in their high estradiol phase outperform participants in their low estradiol phase and demonstrate more rapid learning of exceptions than a male comparison group. A likely mechanism underlying this effect is estradiol's impact on pattern separation and completion pathways in the hippocampus. These results provide novel evidence for the effects of the menstrual cycle on category learning, and underscore the importance of considering female sex-related variables in cognitive neuroscience research.

RESUMEN

Introduction: Women with early ovarian removal (<48 years) have an elevated risk for both late-life Alzheimer's disease (AD) and insomnia, a modifiable risk factor. In early midlife, they also show reduced verbal episodic memory and hippocampal volume. Whether these reductions correlate with a sleep phenotype consistent with insomnia risk remains unexplored. Methods: We recruited thirty-one younger middleaged women with risk-reducing early bilateral salpingo-oophorectomy (BSO), fifteen of whom were taking estradiol-based hormone replacement therapy (BSO+ERT) and sixteen who were not (BSO). Fourteen age-matched premenopausal (AMC) and seventeen spontaneously peri-postmenopausal (SM) women who were ~10y older and not taking ERT were also enrolled. Overnight polysomnography recordings were collected at participants' home across multiple nights (M=2.38 SEM=0.19), along with subjective sleep quality and hot flash ratings. In addition to group comparisons on sleep measures, associations with verbal episodic memory and medial temporal lobe volume were assessed. Results: Increased sleep latency and decreased sleep efficiency were observed on polysomnography recordings of those not taking ERT, consistent with insomnia symptoms. This phenotype was also observed in the older women in SM, implicating ovarian hormone loss. Further, sleep latency was associated with more forgetting on the paragraph recall task, previously shown to be altered in women with early BSO. Both increased sleep latency and reduced sleep efficiency were associated with smaller anterolateral entorhinal cortex volume. Discussion: Together, these findings confirm an association between ovarian hormone loss and insomnia symptoms, and importantly, identify an younger onset age in women with early ovarian removal, which may contribute to poorer cognitive and brain outcomes in these women.

RESUMEN

Sex and Gender Science seeks to better acknowledge that the body cannot be removed from the world it inhabits. We believe that to best answer any neuroscience question, the biological and the social need to be addressed through both objective means to learn, "how it is like" and subjective means to learn, "what it is like." We call bringing the biological and social together, "Situated Neuroscience" and the mixing of approaches to do so, Very Mixed Methods. Taken together, they constitute an approach to Sex and Gender Science. In this chapter, we describe neural phenomena for which considering sex and gender together produces a fuller knowledge base: sleep, pain, memory, and concussion. For these brain phenomena examples, studying only quantitative measures does not reveal the full impact of these lived experiences on the brain but studying only the qualitative would not reveal how the brain responds. We discuss how Sex and Gender Science allows us to begin to bring together biology and its social context and acknowledge where context can contribute to resolving ignorance to offer more expansive, complementary, and interrelating pictures of an intricate neuro-landscape.

RESUMEN

Polycystic-ovary syndrome (PCOS) is the most common endocrine disorder affecting women of reproductive age, and many features associated with PCOS - such as elevated androgens, insulin resistance and inflammation - are known to affect cognition. However, effects of PCOS on cognition are not well-understood. Here we review the current literature on PCOS and cognition, note the extent of PCOS symptomatology studied in relation to cognitive outcomes, and identify key research gaps and common methodological concerns. Findings indicate a pattern of worse performance across cognitive domains and brain measures in women with PCOS relative to non-PCOS controls, as well as a lack of evidence for the common assumption that women with PCOS will have higher performance on tasks with a demonstrated male-advantage due to high testosterone levels. We suggest strategies for moving beyond the focus on elevated androgens, in favor of research practices that account for the nuances and heterogeneity of PCOS symptoms.

RESUMEN

ABSTRACT: As a rite of passage to womanhood, 2 million girls undergo female genital circumcision (FGC)-the tradition of cutting, and often removing parts of the vulva-every year. The current study is the first to focus on the connection between peripheral nerve damage and chronic neuropathic pain in women with FGC. We used mixed methods-quantitative, qualitative, and physiological-to study chronic pain in Somali-Canadian women (N = 14). These women have the most extensive form of FGC, which includes removal of the glans clitoris, labia minora, medial portion of the labia majora, and stitching together the remaining parts of the labia majora. Our results indicate a multifaceted pain experience in women with FGC. Although they report good overall health and very low pain levels on the short form of the McGill Pain Questionnaire, pressure-pain quantitative sensory testing of the vulvar region applied through vulvalgesiometers shows pain thresholds consistent with those reported by women with chronic vulvar pain. Furthermore, qualitative interviews reveal a considerable amount of often debilitating pain in daily life. These results challenge the use of assessment tools offering elicited verbal pain language and highlight the importance of culturally sensitive ways of conceptualizing, measuring, and managing pain.
