title: Physiologic studies of menstrual blood loss. II. Physiologic variables affecting the magnitude of menstrual blood loss.
abstract: The effect of marital status, age, parity, age at menarche, maternal size, arterial blood pressure, position and size of the uterus and hematologic parameters on the magnitude of menstrual blood loss was investigated in 745 randomly selected women in normal physiologic condition, aged 14-49 years, from a city population (Cairo). Menstrual blood loss was found to be related to parity, weight and body surface area and systolic and pulse pressure and to depend mainly upon the hematologic indices reflecting the state of iron balance and anemia in the body.
