DHEA Before
You Dose

The androgen panel every woman should run before starting DHEA — and what to do with the results.

The problem with "low reserve? take DHEA": DHEA is not a one-size-fits-all supplement. Whether it helps — or backfires — depends entirely on your androgen baseline. This checklist gives you the data you actually need.

"Your androgen environment is not a background variable. It is the terrain in which every follicle either thrives or stalls."

Markers to Request Before Starting DHEA
Marker Why It Matters Priority
DHEA-S Your baseline adrenal androgen production. Low DHEA-S is the primary justification for supplementing. Essential
Total Testosterone Elevated total T in context of PCOS or adrenal dysfunction makes DHEA potentially problematic. Essential
Free Testosterone The bioavailable fraction — often more clinically meaningful than total T, especially in androgen excess. Essential
SHBG Low SHBG = more free androgens circulating. Context for interpreting total T and estrogen status. Essential
Androstenedione Upstream androgen. Elevated levels signal the androgen pathway is already overactive before DHEA is added. Important
Fasting Insulin Hyperinsulinaemia drives androgen excess independently of PCOS diagnosis. Do not skip this. Essential
Fasting Glucose Pairs with fasting insulin for metabolic picture. Elevated glucose compounds androgen sensitivity. Essential
LH / FSH Ratio If PCOS traits are present (acne, irregular cycles, oily skin), LH:FSH ratio adds diagnostic weight. LH-dominant pattern is a contra-indication flag. If PCOS traits

DHEA May Be Appropriate If…

  • DHEA-S is genuinely low (bottom quartile of functional range)
  • Total and free testosterone within or below range
  • SHBG normal or high
  • Fasting insulin normal (≤7–8 mIU/L functionally)
  • No PCOS symptoms present
  • DOR confirmed with low AMH or low AFC

Reconsider or Avoid DHEA If…

  • Total or free testosterone already elevated
  • High AMH (PCOS spectrum picture)
  • Fasting insulin elevated (>7–8 mIU/L)
  • Low SHBG with high free androgen index
  • Androstenedione elevated
  • Acne, oily skin, facial hair, hair shedding present
  • LH:FSH ratio >2:1

Stop DHEA Immediately If You Notice These Signs

These are not detox symptoms. They are your androgen system signalling overload. If any of the following appear within weeks of starting DHEA, stop and retest your androgen panel.

New acne Oily skin Hair shedding Irritability Facial hair growth Worsened cycle irregularity

If DHEA Is Appropriate for You

Most fertility research uses 25–75mg/day, with IVF-specific studies often using 75mg split across the day. Micronised DHEA has better oral bioavailability than standard formulations. Run labs 8–12 weeks after initiating to confirm your levels haven't pushed into excess — and always work with a practitioner who can contextualise the results against your full clinical picture. Higher is not better. The goal is adequacy, not supraphysiological.
