Menstrual blood loss--a population study. Variation at different ages and attempts to define normality.
TLDR
It was concluded that a loss of 60-80 ml is normal; losses above 80 ml should be considered pathological and the upper normal limit of menstrual blood loss is established.Abstract:
The previous literature on menstrual blood loss studies was reviewed. A new study was conducted to ascertain the variation of menstrual blood loss at various ages and to establish the upper normal limit of menstrual blood loss. The study involved 476 women of all ages in Goteborg Sweden. Amenorrheic women were excluded from the study. Measurement of hemoglobin concentration plasma iron concentration and hematocrit levels indicated wide variation among women. No statistically significant differences in menstrual blood loss were observed among age groups except that women 50 and older had the highest and women 15 and under the lowest mean loss levels. It was concluded that a loss of 60-80 ml is normal; losses above 80 ml should be considered pathological.read more

Endocrine regulation of menstruation.
TL;DR: A clearer understanding of regulation of normal endometrial function will provide an insight into causes of menstrual dysfunction such as menorrhagia and dysmenorrhea and the development of novel drugs that would target identified aberrations in expression and/or of local uterine factors that are crucial for normal endometricrial function.

The study of menstrual and other blood loss, and consequent iron deficiency, by fe59 whole-body counting.
TL;DR: A recently established method of in vivo radioiron investigation in humans, employing a steel-room whole-body counter, has been applied to the study of Fe(59) absorption and loss in seven menstruating women, six with menorrhagia and hypochromic anemia.
