Progesterone Estrogen Ratio Calculator
Calculate the progesterone to estrogen ratio.
Pg/E2 Ratio = Progesterone (pg/mL) / Estrogen (pg/mL)
Example: Progesterone 15 ng/mL, Estradiol 100 pg/mL = 150:1 ratio (optimal 100-500). Balanced hormones for luteal phase
What is a healthy progesterone to estrogen ratio?
During the luteal phase, optimal ratio is typically 100:1 to 500:1. Lower ratios may indicate estrogen dominance, which can cause various symptoms.
What causes estrogen dominance?
Estrogen dominance can be caused by low progesterone, excess estrogen, poor estrogen metabolism, xenoestrogens, obesity, stress, or hormone replacement therapy.
When should I test these hormones?
For accurate results, test on day 19-21 of your cycle (mid-luteal phase) when progesterone peaks. Postmenopausal women can test anytime.
