Failed IVF? Low AMH? High FSH? Told donor eggs? Book a free Functional Fertility Second Opinion before your next fertility decision.→ fabfertile.com

Low AMH, high FSH, two miscarriages, told donor eggs were her only option. At 43, she conceived naturally. Here's what her clinic missed before the donor egg recommendation.

This episode is for the woman sitting with a donor egg recommendation. Low AMH or high FSH on the chart. Failed IVF or recurrent miscarriage in the history. A clinic that said the numbers leave you no other options.

Sarah Clark walks through the case of a 43-year-old client whose REI told her IVF or donor eggs were her only realistic path. Her FSH was 13.6. Her AMH was low. She had two pregnancy losses behind her. The diagnosis of diminished ovarian reserve was not wrong. The numbers were what they were. What had not happened was a structured investigation of why those numbers looked the way they did and whether the rest of the picture had been missed.

Eighteen months later, she was pregnant naturally with her own eggs.

What the clinic had not investigated was a long list. Her TSH was 3. Accepted as normal, but well above the range her own REI would have flagged before IVF prep. A full thyroid panel was never run.

Her stool DNA test showed H. pylori, an infection that impairs nutrient absorption and drives inflammation. She had been gluten-free everywhere else for years, but she had been taking a weekly communion wafer every Sunday without realizing it counted. The cabergoline she was on was lowering her cholesterol and impairing her ability to make sex hormones.

Her male partner had not been worked up. His semen analysis showed low volume and low concentration. His blood sugar was elevated. His kidney markers showed stress.

The vaginal microbiome had not been tested. The seminal microbiome had not been tested. Her night sweats and disrupted sleep had been mentioned and dismissed.

Her case is not a guarantee that anyone else will get the same outcome. Every case is different. The patterns we found in hers may not be the patterns in yours. But the principle holds: a diagnosis of diminished ovarian reserve, low AMH, or high FSH is a starting point for further investigation, not a complete picture of what is possible.

What this episode covers:

  • Why low AMH and high FSH are not the complete picture when donor eggs are recommended
  • Why a TSH of 3 is not normal for fertility even when a clinic accepts it
  • How H. pylori, hidden gluten, and gut infections affect egg quality and miscarriage risk
  • What a full male partner workup looks like when there has been pregnancy loss or implantation failure
  • What a structured second opinion covers when you have been told IVF or donor eggs are your only path

This episode is for you if:

  • You have low AMH, high FSH, or a diminished ovarian reserve diagnosis
  • You have had a failed IVF cycle, recurrent miscarriage, or implantation failure
  • You have been told donor eggs are your next step and you are not ready to agree before you understand what was actually evaluated
