Estrogen replacement and migraine

Abstract:
Four of every 10 women will experience migraine at some time in their lives, with peak prevalence in middle life. Evidence supports estrogen 'withdrawal' as one of the important triggers of menstrual attacks of migraine without aura. Improvement of migraine without aura postmenopause is generally attributed to the absence of variations in sex hormone levels. Maintaining a stable estrogen environment is best achieved using non-oral estrogen replacement. Unlike migraine without aura, migraine with aura is recognized as a marker for increased risk of ischemic stroke. Research suggests that aura may be more likely to affect women with underlying coagulation disorders. This could, at least in part, account for both increased risk of stroke and the dose related effect of estrogen replacement on the development of aura. Hence women with migraine with aura requiring estrogen replacement should be given the lowest effective dose necessary to control menopause symptoms, by a non-oral route.

Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.

Disorders of the Female Reproductive System
Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
Gonadal and Placental Hormones
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...
