Menstrual Dysfunction
The aim of this presentation is to illustrate how understanding of normal structure and function aids the diagnosis and management of clinical problems. You will be introduced to the main menstrual problems, presented in the context of the ways in which the hypothalamic pituitary ovarian axis may fail. By the end of the presentation you should be able to:
Define the terms that are used to describe common menstrual abnormalities
Describe the effect upon the menstrual cycle of
O Changes in the hypothalamic control of GnRH secretion oChanges in anterior pituitary function
O Changes in ovarian function oChanges in uterine function
O Discriminate between primary and secondary amenorrhoea oIdentify common causes of menorrhagia
oIdentify common causes of painful periods and irregular menstrual cycle
The Menopause
Female reproductive life ends with the menopause. This occurs around 51 years of age and is associated with the depletion of follicles in the ovaries. Gonadotrophins are no longer able to stimulate follicular development, so the interaction between the hypothalamus, pituitary and gonads that maintains reproductive cycles is broken. Oestrogen and progesterone levels fall dramatically producing a wide variety of physiological effects including vaso-motor changes
(„hot flushes?) mood changes and others. Lower oestrogen levels may also be associated with the development of osteoporosis.
Whether there is a „male menopause? or „andropause? is debatable. Spermatogenesis continues throughout life but incidence of loss of libido, impotence and inability to reach orgasm increase with age. Testosterone levels may decrease but without rise in LH (or FSH) suggesting a change in the feedback control mechanism.
