2. The control group: women between 20-35 years of age who practice low level of physical activity, as defined by International Physical Activity Questionnaire , for the past 3 years
Women who meet the criteria for inclusion for will be recruited to the study after signing a consent form. Recruitment will be done through sport centers. The control group will include women being examined in gynecologic emergency department, after signing a consent form, if they meet the control group's inclusion criteria. These women will be asked to fulfill the International Physical Activity Questionnaire and additional questionnaire regarding relevant demographic and medical information (see below). Blood samples to anti-mullerian hormone , leptin, and hormonal profile will be obtained in day 3 of menstruation. Ultrasound will be performed to measure Antral Follicular count and ovarian blood flow.
Data collection:
1. Demographic information on age, weight, height, BMI, marital status
2. Medical information regarding chronic diseases and medications
3. Obstetrical history
4. Information regarding physical activities in the version of International Physical Activity Questionnaire .

6. Hormonal profile - Follicle-stimulating hormone , Luteinizing hormone , progesterone, Estradiol, Thyroid-stimulating hormone .
7. Antral Follicle Count, Anti-mullerian hormone
8. Leptin levels -reflecting metabolic changes.
