The athletic females were instructed to refrain from performing strenuous exercise on the day of sampling. Blood samples were separated and stored at -80°C till analysis of serum estradiol levels. Serum estradiol levels were measured to evaluate the menstrual function. The manufacturer indicated the following reference intervals for healthy females: Estradiol 40-350 pg/ml.
- Menstrual history characteristics [3 months]
