Hinweis der Redaktion

  • Normal menstrual bleeding due to postovulatory estrogen-progesterone withdrawal is stable and precisely regulated. It is generally agreed that the normal menstrual cycle will be between 24 and 35 days in length, measured from the first day of menstrual flow of once cycle to the first day of the next cycle. The usual duration of menstrual flow is 4-6 days, but many women may have a flow for as little as 2 days or as much as 7 days.
    Normal menstruation also tends to be consistent in the amount of blood that is lost. The usual volume of menstrual blood loss is 30 mL, and a menstrual flow greater than 80 mL is considered abnormal. In practice, however, it is virtually impossible for either the patient or her clinician to estimate menstrual volume of blood loss accurately.
  • Normal human menstrual function is dependent upon an intricate series of hormonal actions linking the neuronal nuclei of the hypothalamus to the pituitary gland, which subsequently stimulates the ovaries to produce sex-steroids that act upon the endometrial lining of the uterus. This pathway is known as the hypothalamic-pituitary-ovarian (HPO) axis. Along the HPO axis there is a complex system of positive and negative feedback signals that allow the end-organs to communicate with the higher centers.
    Late in the menstrual cycle, the arcuate nucleus of the hypothalamus generates carefully timed pulses of gonadotropin-releasing hormone (GnRH), which stimulates cells of the anterior pituitary gland to produce follicle-stimulating hormone (FSH) and, to a smaller extent, luteinizing hormone (LH). In the right proportion, FSH will recruit a cohort of ovarian follicles for development. At the same time, pituitary FSH/LH circulates back to the hypothalamus, exerting a negative feedback control on pulses of GnRH to limit recruitment of additional follicles.
    From this cohort of ovarian follicles, a dominant follicle is selected by the seventh day of the next menstrual cycle. This one follicle matures and proceeds to ovulation, usually on the 14th day. While maturing, the dominant follicle secretes increasing amounts of estradiol, which initiates ovulation through positive feedback by causing a massive and sudden release of LH from the pituitary (LH surge).
    In the endometrial lining, rising levels of estradiol produced by the follicle stimulate proliferative growth of epithelial and stromal elements. This phase of growth is termed the proliferative phase and, under the influence of estradiol, the endometrium grows in height and becomes rich in progesterone-receptors.
    Once the LH-surge occurs, the ovum is released, and the follicle collapses to become the corpus luteum. The corpus luteum is a sub-organ within the ovary with a lifespan of approximately 10 days that produces large amounts of progesterone. Under this progestagenic influence the endometrium enters the secretory phase. Endometrial growth stops, and the stroma becomes more compact and stable. The glandular epithelium develops glycogen vacuoles to prepare for implantation of an embryo. If implantation fails to occur, then the corpus luteum undergoes involution and production of progesterone is withdrawn. Upon progesterone-withdrawal, the endometrial lining collapses, resulting in menstruation.
    Once levels of progesterone and estradiol decline, the hypothalamus and pituitary escape the influence of negative feedback, and FSH values rise again for the subsequent cycle.
