NCT07152262
This study aims to investigate the effects of different phases of the menstrual cycle on gait spatiotemporal characteristics, pelvic kinematics, and sleep quality in healthy women aged 18-35 years with regular menstrual cycles. Participants will be assessed in three phases of the cycle: early follicular (days 1-3), ovulation (days 7-9, confirmed by ovulation test), and luteal (days 20-23). Gait parameters and pelvic kinematics will be evaluated using the BTS-G walk sensor system, while sleep quality will be assessed with the Pittsburgh Sleep Quality Index (PSQI). The study seeks to determine whether physiological and hormonal changes during menstrual phases lead to measurable differences in gait, pelvic motion, and sleep quality.
NCT06771583
This research is being done to examine epigenetic markers and mood changes across the menstrual cycle, particularly in premenstrual dysphoric disorder (PMDD). The investigators previously identified epigenetic biomarkers of postpartum depression, another reproductive affective disorder, and in this study aim to determine if these biomarkers also distinguish PMDD cases from healthy controls at different points in the menstrual cycle. By collecting biological samples (such as blood) and monitoring mood changes across the menstrual cycle, the investigators will be able to determine whether these epigenetic markers are associated with PMDD. The investigators plan to study these epigenetic markers during the follicular phase (roughly the first half of the menstrual cycle, from menses until ovulation) and the luteal phase (roughly the second half of the menstrual cycle, from ovulation to menses). The investigators will study this in two groups: 1) individuals who do NOT have premenstrual mood symptoms, and 2) individuals with premenstrual syndrome/premenstrual dysphoric disorder (PMS/PMDD). The results will provide a comprehensive view of the changes in these systems across the menstrual cycle. This will add to the investigators understanding of the mechanisms that may cause PMS/PMDD.
NCT07462286
This study examines how different phases of the menstrual cycle are associated with selected performance and musculoskeletal parameters in physically active women aged 18-35 years. Participants will track their menstrual cycle using a mobile app for approximately 2 months and attend 3 laboratory visits scheduled to specific cycle phases. At each visit, participants will complete non-invasive assessments including lower-limb strength/performance testing, musculoskeletal measurements (muscle and tendon properties), body composition assessment, and symptom-related questionnaires. The goal is to improve understanding of physiological variability across the menstrual cycle and support evidence-based planning of training, testing, and clinical practice in women.
NCT07456202
This prospective observational cohort study aims to evaluate the association between menstrual phase (determined by postoperative serum progesterone levels), intraoperative anesthetic consumption, and the incidence and severity of postoperative nausea and vomiting (PONV) in female patients undergoing cholecystectomy. Intraoperative anesthetic requirements will be recorded, and postoperative nausea and vomiting will be assessed using standardized scoring systems.
NCT06533501
The existing guidelines for dietary amino acid intake for women are set the same as those established for men. These recommendations might not be appropriate for women, as they do not take into consideration important differences between male and female physiology, like the menstrual cycle. This study aims to determine the leucine requirements during the phases of the menstrual cycle. Leucine is an essential amino acid (cannot be made naturally in the body) and is necessary for protein synthesis, and other important cellular functions. Consuming an adequate amount daily is crucial for maintaining overall health. An innovative, non-invasive technique utilizing pre-determined diets, safe stable isotopes, and a simple breath collection method will be used. Previous work done by Elango Lab investigators has applied this method to investigate other amino acids in pregnant, non-pregnant, and lactating women.
NCT07322874
The aim of the study is to investigate the effect of the different menstrual cycle phases on the recovery from exercise-induced muscle injury in eumenorrheic women. For this purpose, in a cross-over, randomized study, at least 10 healthy eumenorrheic women aged 18-35 years will participate. In a random order, the participants will perform 45 min downhill (-15% slope) running on a treadmill at 70% HRmax followed by a maximal time-trial (95% HRmax) to exhaustion: i) during the follicular phase and ii) during the luteal phase. Before the exercise protocol, as well as at 24 h, 48 h and 72 h following exercise, complete blood count, delayed onset of muscle soreness (DOMS), creatine kinase activity, countermovement jump, isometric, concentric and eccentric strength of knee extensors and knee flexors, will be assessed. In addition, lactic acid concentration will be assessed before and immediately following exercise, and DOMS will be assessed immediately after the end of exercise. Following a washout period of ≥28 days (depending on the length of the menstrual cycle), participants will repeat the exact same procedure for the remaining phase of the menstrual cycle.
NCT07337941
This study aims to examine the effects of menstrual cycle phase and a virtual reality (VR) intervention on preoperative anxiety in female patients scheduled for septorhinoplasty surgery.
NCT07248046
This study will compare different combinations of fertility signs (cervical mucus (CM), luteinizing hormone \[LH\], pregnanediol glucuronide \[PDG\], and basal body temperature \[BBT\]) to determine which are most reliable for identifying ovulation and luteal phase length. Thirty existing Premom App users will track daily observations for three menstrual cycles. Participants will record mucus, perform urine tests, upload test strip photos to the Premom App, and measure BBT. Both participant readings and AI-assisted app readings will be analyzed. The main goal is to find which marker pairings give the most accurate picture of ovulation timing and luteal phase length. Secondary goals include understanding ease of use, the number of tests required, and whether the app improves accuracy.
NCT07286136
This 12-week, 100% virtual single-group open-label trial evaluates the Cycle SyncingⓇ Method using the MyFLO app, MIRA hormonal monitoring, and continuous glucose monitoring to assess reduction in menstrual cycle symptom burden and hormonal regulation.
NCT07258576
The muscles of the body are constantly breaking down old proteins and building new ones. These two processes, protein breakdown and protein synthesis, together are known as protein turnover. Protein turnover is essential for maintaining healthy muscle. Despite its importance, females have historically been underrepresented in protein metabolism research. A long-standing assumption has been that fluctuations in female sex hormones such as estrogen and progesterone, whether across the natural menstrual cycle or in individuals using oral contraceptives (OCs), make metabolism and training responses too variable to study. Because of this, many researchers have excluded female participants for logistical reasons. Resistance exercise, such as weightlifting, is the most effective way to increase muscle size and strength. Each resistance-training session triggers muscle protein synthesis (MPS), the process by which new muscle proteins are built. Consuming dietary protein or individual amino acids further increases the rate at which new proteins are formed. Over time, higher rates of protein synthesis support muscle growth and the maintenance of other lean tissues in the body. The purpose of this study is to examine how menstrual cycle phases and OC use influence the synthesis of proteins in both muscle tissue and the rest of the body. Improving scientific understanding in this area will support more effective, evidence-based training and nutrition recommendations for females.
NCT05936424
The primary purpose of this study is to employ state-of-the-art methods to fill current knowledge gaps on the effects of the menstrual cycle on resistance exercise training adaptations. This work will reduce the sex gap present in exercise physiology, improving women's health information by yielding a deeper understanding of the effect of female physiology on exercise adaptations and subsequent health benefits. Employing a unilateral training design, participant's will have their legs randomized to one of four groups: non-exercise control (CON), exercise control (EX), Follicular based training (FOL), Luteal based training (LUT) Researchers will compare these conditions to see if there are greater benefits to prioritizing resistance training around phases of the menstrual cycle,
NCT07137299
The goal of this observational study is to evaluate the impact of different hysterectomy (removal of the uterus) techniques on the risk of pelvic organ prolapse (situation when one or more of your pelvic organs like your bladder, uterus, or rectum have dropped down or slipped out of their normal position, sometimes even bulging into the vagina) and urinary incontinence (leaking urine unexpectedly) in women aged 18-85 who underwent hysterectomy or supracervical hysterectomy (removing of the uterus without its cervix) for benign (not cancer) conditions. The main question is: to check how different surgical technique (laparoscopic, with opening the abdomen, vaginal and robotic) increase the risk of pelvic organ prolapse or urinary incontinence There is no randomization or control group; comparisons will be made between surgery types based on clinical and questionnaire data. Participants will: * Receive an invitation to participate if they underwent hysterectomy between 2021-2025. * Fill out validated quality of life questionnaires (P-QOL, POPDI-6, PFIQ-7) every two years. * Attend follow-up clinical pelvic exams every two years to assess vaginal cuff healing, pelvic organ prolapses (POP-Q system), and urinary symptoms. This prospective, non-commercial, multicenter study plans to enroll 2,000 women and will run from July 1, 2025, to July 1, 2036
NCT07026396
In this study, the effect of creative drama-based education on menstruation attitudes and genital hygiene behaviors of adolescent girls aged 10-14 years was investigated. After screening, a total of 64 students were included in the study. Data were collected using Personal Information Form, Genital Hygiene Behavior Scale and Menstruation Attitude Scale.The creative drama method can create an open and safe communication environment by reducing the embarrassment or shyness of young people when dealing with taboo subjects such as menstruation. This approach supported the perception of menstruation as a natural biological process and contributed to the participants developing a more positive attitude towards the subject.
NCT06558266
Hormonal fluctuations occur during the menstrual cycle and can affect cognition. For example, an increase in estrogen levels has been reported to temporarily enhance auditory perception of newly formed stimuli. It has been suggested that fluctuations in hormone levels can alter cognitive performance throughout the menstrual cycle because these fluctuations impact the neurobiology of the brain regions involved in cognition and emotion processing. Mental imagery (MI) refers to the mental process in which an individual imagines performing a movement without actually executing the movement. The effects of hormonal fluctuations on cognitive-perceptual skills have been mentioned above. In light of the above information, this study was planned to examine the relationship between menstrual symptom characteristics and mental imagery ability and to compare women s mental imagery abilities according to the phases of the menstrual cycle.
NCT06789354
The study explores the dynamic interplay between body awareness and body perception across the menstrual cycle's phases, emphasizing hormonal influences on these dimensions. Conducted with 43 female participants aged 18-35, this research highlights significant variability in body-related experiences tied to hormonal fluctuations. The study aims to address the gap in understanding how menstrual cycle phases impact women's body awareness-sensitivity to physiological states-and body perception, encompassing self-image and physical self-evaluation.
NCT06750250
The menstrual cycle is a term to describe the sequence of events that occur in body as it prepares for the possibility of pregnancy each month. The average length of a menstrual cycle is 28 days. However a cycle can range in length from 21 days to about 35 days and still normal. The menstrual cycle is the time from the first day of your menstrual period until the first day of your next menstrual period. Every person's cycle is slightly different, but the process is the same. Menstruation is the monthly shedding of the lining of the uterus. Menstrual blood which is partly blood and partly tissue from the inside of the uterus flows from the uterus through the cervix and out of the body through vagina. Some people experience symptoms of menstruation and others don't. The intensity of these symptoms can also vary. The most common symptom is cramps. The cramping you feel in your pelvic area is your uterus contracting to release its lining. Menstrual cycle have four phases, menses phase (3 to 7 days of your periods), follicular phase (during the 10 to 14 days), ovulation phase (14 day if cycle is 28 days) and luteal phase (15 to 28 days).These will a Randomized control trial conduct on 42 participants. The data will be collected ffrom ladies gym and muscle work gym by using non-probability convenience sampling technique. The age between 18-25 years participants will perform the aerobic exercises during the different phases of menstrual cycle. A sample will be divided into two groups each group have 21 participants. The Group A control group will Education and Self-Management about health and fitness and perform the walk. Group B intervention group will be given the Aerobic exercise (cycling, treadmill and running). The participants assessed with Borg scale for rate perceived exertion, berg balance questionnaire use for performance test parameters and menstrual stress questionnaire use for behaviour. Data will be analyzed by using SPSS version 26.0.
NCT05347667
Skeletal muscle size and function is regulated by various factors, including hormones. While we understand the role of male sex hormones (testosterone), we aren't sure how female sex hormones (estrogen and progesterone) influence muscle mass and strength. Female physiology is unique in that hormones fluctuate throughout the menstrual cycle. In the first phase (follicular phase) following menstruation, estrogen levels are high while progesterone levels are low. In the second phase (luteal phase), progesterone levels are high. Females are often excluded from studies because researchers are concerned that the menstrual cycle might affect the results. The purpose of this study is to investigate the response to resistance exercise in each phase of the menstrual cycle.
NCT06683248
The study aims to investigate the effects of sleep deprivation on women's health across different phases of the menstrual cycle.
NCT06679491
The goal of this clinical trial is to assess the impact of menstrual cycle-based resistance training on neuromuscular function in female athletes. The primary questions it aims to answer are : * Does varying resistance training intensity according to menstrual phases improve maximal knee extensor strength? * How do different training protocols affect voluntary activation, rate of force development, muscle stiffness, and vertical jump height? Researchers will compare natural menstrual cycle groups with an oral contraceptive control group to determine if menstrual phase-specific training influences neuromuscular adaptations. Participants will: * Undergo 2 weekly resistance training sessions over 13 weeks with intensity adjustments based on menstrual phase * Complete periodic neuromuscular assessments across three menstrual phases: early follicular, late follicular, and mid-luteal before and after resistance training intervention
