Hormonal Fluctuations in Women's Lives

[Nelson Vergel]

Hormonal fluctuation during (A) a normal menstrual cycle, (B) while taking an oral contraceptive (OC) containing both estrogen and progesterone, and (C) in the years before and after menopause.

Strange to leave out testosterone.

Dynamics of serum testosterone during the menstrual cycle evaluated by daily measurements with an ID-LC–MS/MS method and a 2nd generation automated immunoassay

Testosterone concentrations in normally cycling women are assumed to be elevated around the time of ovulation. The clinical relevance of changing test…

Homework, convert this ref range over to pg/ml and compare with concentrations of the hormones in the first post. What do you conclude about the TT/E2 ratio in pre-menopausal women?

Reexamination of Testosterone, Dihydrotestosterone, Estradiol and Estrone Levels across the Menstrual Cycle and in Postmenopausal Women Measured by Liquid Chromatography Tandem Mass Spectrometry - PMC

Measuring serum androgen levels in women has been challenging due to limitations in method accuracy, precision sensitivity and specificity at low hormone levels. The clinical significance of changes in sex steroids across the menstrual cycle and ...

Testosterone in women--the clinical significance - PubMed

Testosterone is an essential hormone for women, with physiological actions mediated directly or via aromatisation to oestradiol throughout the body. Despite the crucial role of testosterone and the high circulating concentrations of this hormone relative to oestradiol in women, studies of its...
