Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Methods: This prospective study will be included 70 women with idiopathic premature ovarian insufficiency and 70 controls. The blood/urine/hair for analyses will be obtained at the early follicular phase of the menstrual cycle and plasma zinc (Zn), copper (Cu), calcium (Ca), iron (Fe), manganese (Mn), selenium (Se), strontium (Sr), aluminum (Al), antimonium (Sb), phosphorus (P), magnesium (Mg), sodium (Na), potassium (K), barium (Ba) and thallium (Tl) levels will be measured using inductively coupled plasma-mass spectrometry.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Women between the ages of 18-39 will be included. A volunteer group of healthy women who will be visited the gynecology clinic for routine examinations and women who will be admitted for pre-pregnancy tests will be invited randomly to this research as a control group. Healthy women, who will be returned during their early follicular phase of the menstrual cycle, will be recruited as the control group subjects. The exclusion criteria will be as follows: women with evidence for karyotypic, metabolic, toxic, or iatrogenic cause of the ovarian insufficiency and any women who use any medication for POI treatment. At enrollment, for both groups, the authors will be collected data about age, height, weight, BMI, age of menarche, obstetrics history, history of smoking, regular exercise and family history of POI. At enrolment, all patients will be underwent vaginal ultrasonography for the assessment of antral follicle count (AFC) and venous blood sample from the antecubital veins for measuring plasma concentration of zinc (Zn), copper (Cu), calcium (Ca), iron (Fe), manganese (Mn), selenium (Se), strontium (Sr), aluminum (Al), antimonium (Sb), phosphorus (P), magnesium (Mg), sodium (Na), potassium (K), barium (Ba) and thallium (Tl), Follicle-stimulating hormone (FSH), E2, anti-mullerian hormone (AMH) and complete blood count (CBC). In control subjects, venous blood samples and AFC will be collected during the early follicular phase of the menstrual cycle. Urine and hair samples will be collected at the same time. The plasma and urine samples will be stored in aliquots at -80°C prior to the analyses of zinc (Zn), copper (Cu), calcium (Ca), iron (Fe), manganese (Mn), selenium (Se), strontium (Sr), aluminum (Al), antimonium (Sb), phosphorus (P), magnesium (Mg), sodium (Na), potassium (K), barium (Ba) and thallium (Tl). Hair samples will be stored in envelopes at room temperature. The plasma/urine/hair zinc (Zn), copper (Cu), calcium (Ca), iron (Fe), manganese (Mn), selenium (Se), strontium (Sr), aluminum (Al), antimonium (Sb), phosphorus (P), magnesium (Mg), sodium (Na), potassium (K), barium (Ba) and thallium (Tl) level will be measured using inductively coupled plasma-mass spectrometry. Then, this study will be determined plasma/urine/hair zinc (Zn), copper (Cu), calcium (Ca), iron (Fe), manganese (Mn), selenium (Se), strontium (Sr), aluminum (Al), antimonium (Sb), phosphorus (P), magnesium (Mg), sodium (Na), potassium (K), barium (Ba) and thallium (Tl) levels in women with POI (n=70) compared to those of volunteer healthy women (n=70). Then, these macroelements levels will be compared in both groups.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Premature ovarian insufficiency (POI)
POI is a clinical syndrome defined by loss of ovarian activity before the age of 40 years. POI is characterized by menstrual disturbance (amenorrhea or oligomenorrhea) with raised gonadotropins and low estradiol.
ultrasound assessment
Zinc (Zn), copper (Cu), calcium (Ca), iron (Fe), manganese (Mn), selenium (Se), strontium (Sr), aluminum (Al), antimonium (Sb), phosphorus (P), magnesium (Mg), sodium (Na), potassium (K), barium (Ba) and thallium (Tl) measurements (µg/L,mean±SD)
Control group
The study population will be consisted of 70 women with POI as the study group and 70 patients with normal healthy women as the control group. A volunteer group of healthy women who will be visited the gynaecology clinic for routine examinations and women who will be admitted for pre-pregnancy tests will be invited randomly to this research as a control group.
