Mapping changes in women's visual functions during the menstrual cycle: narrative review

The effect of the menstrual cycle on physical performance is being increasingly recognised as a key consideration for women’s sport and a critical field for further research. This narrative review explores the findings of studies investigating the effects of menstrual cycle phase on perceived and objectively measured performance in an athletic population. Studies examining perceived performance consistently report that female athletes identify their performance to be relatively worse during the early follicular and late luteal phases. Studies examining objective performance (using anaerobic, aerobic or strength-related tests) do not report clear, consistent effects of the impact of menstrual cycle phase on physical performance. Overall sport performance can be influenced by both perceived and physical factors. Hence, to optimise performance and management of eumenorrheic female athletes, there is a need for further research to quantify the impact of menstrual cycle phase on perceived and physical performance outcomes and to identify factors affecting variability in objective performance outcomes between studies.

Menstrual Disturbances

Context: Menstrual cycle is considered the fifth vital sign among women. This study aimed to summarize the menstrual disturbances in different endocrine disorders. Evidence Acquisition: 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. Results: 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. Conclusions: 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.

Visual Disturbances

Migraine, the most frequent neurological ailment, affects visual processing during and between attacks. Most visual disturbances associated with migraine can be explained by increased neural hyperexcitability, as suggested by clinical, physiological and neuroimaging evidence. Here, we review how simple (e.g., patterns, color) visual functions can be affected in patients with migraine, describe the different complex manifestations of the so-called Alice in Wonderland Syndrome, and discuss how visual stimuli can trigger migraine attacks. We also reinforce the importance of a thorough, proactive examination of visual function in people with migraine.

The U.S

Today it is estimated that one of every three women in the U.S. will have problems achieving pregnancy. 20-30% of these women will have some form of oviductal problems as the etiology of their infertility. Chronically damaged oviducts present problems with loss of both ciliary and microvillar epithelial cell surfaces. Estradiol is known to influence cyclic patterns in secretory cell microvilli and tubal ciliogenesis, The purpose of this study was to assess whether estrogen therapy could stimulate ciliogenesis in chronically damaged human fallopian tubes.Tissues from large hydrosalpinges were obtained from six women undergoing tuboplastic repair while in the early proliferative phase of fheir menstrual cycle. In each case the damaged tissue was rinsed in heparinized Ringers-lactate and quartered.
