Background:
Sex hormones play a role in both the risk and the prognosis of multiple sclerosis (MS). Considering all stages of women's reproductive life, data regarding the influence of menopause on MS and vice versa are scarce.
Objective:
The aim of this study was to review the evidence addressing the relationship between menopause and MS.
Methods:
A literature search through PubMed was conducted, selecting studies that assessed (1) the influence of menopause in the MS course, (2) the influence of MS and disease-modifying drugs (DMD) on the development of menopause and (3) the effect of hormone replacement therapy (HRT) on symptoms of menopausal MS patients.
Results:
(1) Most studies suggest menopause may transitorily aggravate MS symptoms. Two studies found an inflexion point on the Expanding Disability Status Scale (EDSS) with clinical worsening during the menopausal transition. Another study considering full EDSS trajectories from clinically isolated syndrome to postmenopause did not find such an EDSS inflection; (2) MS and DMD do not seem to alter the age of menopause onset; and (3) HRT in menopausal MS patients has not shown consistent benefits.
Conclusion:
Menopause seems to be associated with transient symptom worsening, but the existence of an inflection in disability progression is still controversial. Properly designed studies are necessary to achieve conclusive results.

01:22Hormonal 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...

01:30Hormonal 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...
01:19Factors Affecting Drug Biotransformation: Biological
Species differences: Variations in enzyme systems across species can cause disparities in drug metabolism. For instance, humans may metabolize certain drugs faster than rodents, altering therapeutic effects.
Strain differences: Genetic variations within a species can result in differing enzyme activity, impacting drug response and toxicity. For example, some mouse strains may...
