Active clinical trials for "Menstruation Disturbances"

The investigators would like to determine how aspects of metabolism and age influence ovarian function. The purpose of the study is to understand how nutrition and metabolism relate to follicle development in women with regular cycles, irregular cycles, or polycystic ovary syndrome (PCOS). We also plan to identify lifestyle factors associated with PCOS and understand how diet and activity levels impact features of PCOS.

The purpose of this study is to study whether a drug called tamoxifen can reduce vaginal bleeding in women who are using the Etonogestrel contraceptive implant.

This study examines the effects of estrogen and progesterone on mood, the stress response, and brain function and behavior in women with premenstrual syndrome. Previously this study has demonstrated leuprolide acetate (Lupron (Registered Trademark)) to be an effective treatment for PMS. The current purpose of this study is to evaluate how low levels of estrogen and progesterone (that occur during treatment with leuprolide acetate) compare to menstrual cycle levels of estrogen and progesterone (given during individual months of hormone add-back) on a variety of physiologic measures (brain imaging, stress testing, etc.) in women with PMS. PMS is a condition characterized by changes in mood and behavior that occur during the second phase of the normal menstrual cycle (luteal phase). This study will investigate possible hormonal causes of PMS by temporarily stopping the menstrual cycle with leuprolide acetate and then giving, in sequence, the menstrual cycle hormones progesterone and estrogen. The results of these hormonal studies will be compared between women with PMS and healthy volunteers without PMS (see also protocol 92-M-0174). At study entry, participants will undergo a physical examination. Blood, urine, and pregnancy tests will be performed. Cognitive functioning and stress response will be evaluated during the study along with brain imaging and genetic studies.

PCOS patients were treated every day, with one sachet containing 2000 mg myo-inositol, 500 mg L-tyrosine, 40 mcg chromium picolinate, 55 mcg selenium, 200 mcg folic acid. All patients underwent, before starting the therapy, after 3 months and 6 months, hormonal evaluation , hirsutism scoring and ovulation assesment. Most of them during the treatment improved their symptoms.

A growing body of epidemiological and biological evidence strongly suggests that physical activity may reduce the risk of breast cancer. Although the mechanism remains unclear, possible links between reduced risk and exercise include favorable alterations in body composition and positive changes in the hormonal milieu. One hormonal biomarker of breast cancer, circulating estrogen, is postulated to be reduced by chronic physical activity, presumably due to disruptive effects of exercise upon menstrual cyclicity, and the potential for loss of body fat with subsequent reductions in the peripheral biosynthesis of circulating estrogens. Although studies have shown that chronic exercise can reduce circulating estrogen, we know little about the magnitude and duration of exposure to an energy deficit required for these changes. Additionally, no studies have addressed the degree to which peripheral production of estrone, versus the ovarian production of estradiol, is altered with exercise that promotes weight/fat loss. A second biomarker of breast cancer, insulin-like growth factor-1 (IGF-1), is presumably increased with exercise but reduced with exercise if energy balance is negative. No prospective studies have addressed whether a moderate aerobic exercise program that results in weight loss will lead to significant changes in IGF-I levels, particularly in individuals of differing initial energy stores. Metabolic energy availability is an important contributing factor in the development of reproductive cancers. However, current methods for assessing energy availability, which include anthropometric measures, calculations of energy balance, evaluation of various serum and urinary biomarkers are prone to measurement error, not sensitive to alterations in energy availability, and are sometimes affected by disease states. The current project includes the introduction of a novel approach to estimating energy status by measuring metabolic hormones in plasma: insulin, IGF-I, insulin-like growth factor binding protein-3 (IGFBP-3) and leptin. This study tested whether a program of moderate aerobic exercise that is combined with a moderate level of dietary restriction would result in significant decreases in two biomarkers of breast cancer, circulating estrogens and IGF-I.

Menstruation is a process in which metabolic and hormonal changes occur periodically every month to maintain reproductive functions in women. This cycle, which continues from menarche to menopause, repeats approximately every 28 days and lasts 3-7 days (1). The menstrual cycle is divided into three phases, the follicular phase, the ovulation phase, and the luteal phase, in which the levels of estrogen and progesterone hormones change (2,3). In this cycle, which is regulated by the hormones released from the pituitary, hypothalamus and ovary, changes occur not only in the genital organs, but also in the nervous system, cardiovascular system, respiratory system, musculoskeletal system and metabolic functions (4). Responses to these changes, which cause physiological stress in the organism in women, are perceived in different degrees. The presence of recurrent abnormal bleeding or excessive pain may be a sign of various menstrual disorders (5). Evaluation of menstrual problems that negatively affect women's mood, social and work life is clinically important (6,7). The scale, called Menstrual Distress Questionnaire (MEDI-Q), was developed by Vannuccini et al. (2021), it is a tool that comprehensively evaluates menstrual problems (8). MEDI-Q assesses the effects of menstrual symptoms on quality of life, recreational activities, work and social relationships. It consists of 25 items covering different areas of menstruation-related symptoms such as pain, discomfort, psychological and cognitive changes, and gastrointestinal disturbances. The level of distress caused by each symptom is assessed in the menstrual cycle phases, taking into account not only its impact on functionality and quality of life, but also its frequency. MEDI-Q is a scale with good test-retest reliability and internal consistency (Cronbach's = 0.85) (8,9). The scale provides a total score (MEDI-Q Total Score) and three subscales that assess general menstrual distress. Subscales; the number of distressing symptoms (MS) during menstruation, the mean level of distress related to menstrual symptoms (MSD), and the Menstrual Specificity Index (MESI) (8,9), which measures the proportion of symptoms at which distress exacerbates during the menstrual phase.

The purpose of this study is to examine the effects of increased food intake on the menstrual cycle and bone health in physically active women who have irregular or absent menstrual cycles. This study will examine whether a 12 month period of increased food intake will cause menstrual cycles to resume and help bones get stronger.

Aromatase inhibitors have been approved for use in postmenopausal women to treat and prevent breast cancer. They act by blocking the action of the enzyme, aromatase, that is necessary for the production of estradiol. This class of drugs, aromatase inhibitors, are very effective in reducing estradiol levels in postmenopausal women and in treating estrogen receptor positive breast cancers. This study is examining the effect of a specific inhibitor, anastrozole, on endometrial thickness in premenopausal women. The endometrium is sensitive to estradiol and also has local aromatase which, if inhibited, may result in reduced endometrial thickness. The main hypothesis is that anastrozole can be administered at any time during the menstrual cycle and reduce endometrial thickness compared to placebo.

This study aims to test the use of a 10 mm laparoscopy trocar tip for formation of a new vaginal orifice with preservation of an annular hymen (Darwish hymenotomy technique) in cases of post pubertal imperforate hymen (IH). A prospective interventional case series done at a minimally invasive surgery unit of a tertiary university hospital between July 2013 and October 2019 comprising patients with primary amenorrhea and hematocolpus. Circular hymenotomy using a 10 mm laparoscopy trocar tip and sleeve done under general anesthesia was done in 36 cases. Documented vaginal patency with formation of an annular hymen in all cases was reported on follow-up visits without reported intraoperative complications. Patient and family satisfaction with excellent sensation of preserved hymen was also documented. Using a 10 mm laparoscopy trocar tip for formation of a new vaginal opening with preservation of annular hymen (Darwish technique) in cases of postpubertal IH is a simple, effective and safe procedure suitable for Islamic and conservative societies with excellent impact on the psychological and emotional status of the patient and her family.

Hormonal fluctuations present during the ovarian cycle may have a strong influence on physiological and psychological aspects on physical performance in women. The aspects surrounding performance and ovarian cycles in women during different phases of the cycle, are still current and should be debated in the literature, as the available evidence has conflicting results. In addition to the above, new ergogenic methods have been studied to improve the sports scenario in different populations. Research on the use of ergogenic electrophysical resources so that hormonal effects may possibly be mitigated, allowing women to use this resource and improving their physical performance is still scarce in the current literature.
