Abstract:
Through studies on the hormonal threshold area of menstruation had shown that the hormonal threshold area of menstruation is not a right line but an area consisted of two limits, superior and inferior ones. Menstrual bleeding occurred only when the curve of hormonal effect on development of the endometrium is situated in this area of two limits. Above or under that threshold area the curve of hormonal effect on development does not cause endometrial hemorrhage. The author also showed that the superior limit has a mean value 57.65±43.36 pmol/L and the inferior one is at 29.27±19.43 pmol/L of estradiol. Basing on the above statement the author suggested that the menstruation may be defined as occurred when the curve of hormonal effect on endometrial development situates in a threshold area of menstrual bleeding and not when the sexual steroids go down under a certain threshold as earlier
