This study was conducted to investigate the hormonal effect of different menstrual phases on hip abductor torque in non-athletic females. Twenty-seven non-athletic virginal females participated in this study. They had regular menstrual cycles. Their ages ranged from 20 to 30 years and their body mass index (BMI) was < 30 kg/m². Serum estradiol, serum progesterone and hip abductor torque were assessed during the early follicular and mid-luteal phases of the menstrual cycle. Results showed that there was a statistically significant increase in serum progesterone(P=0.0001) and hip abductor torque (P=0.047) in the mid-luteal phase compared to the early follicular phase, while the increase in serum estradiol was non-significant (P=0.843). Additionally, there was a significant negative correlation between serum estradiol and hip abductor torque(P=0.04) only in the early follicular phase. It can be concluded that the non-athletic females showed significant decreases in the progesterone level and hip abductor torque in the early follicular phase. The significant negative correlation between the serum estradiol and hip abductor torque indicates that the females with high estradiol level at the early follicular phase could have low abductor torque that increases the liability to injury
