Told Donor Eggs After Failed IVF? The Gut Pattern Your Clinic Did Not Test

Told donor eggs after failed IVF? There is a category of testing that your fertility clinic does not run. We rarely run a stool test and find nothing.

The IVF cycle did not work. Maybe it was poor response. Maybe it was canceled before retrieval. Maybe you got embryos and they arrested. Maybe the transfer failed. Your clinic looked at your numbers and told you donor eggs.

In this episode, Sarah Clark walks through the gut pattern the Fab Fertile team sees in women who come to us after failed IVF with a donor egg recommendation, and why this pattern changes the picture before the next decision.

What this episode covers:

H. pylori. One of the most common findings in the women who come to us after failed IVF. It impairs absorption of iron, vitamin B12, and zinc, the nutrients that affect egg quality, thyroid function, and hormone production. It is passed back and forth between partners through saliva. If you have it, there is a strong chance your partner has it too.

Parasites, giardia, blastocystis. Common findings. Rarely tested at the fertility clinic.

Bacterial overgrowth, including streptococcus. Fungal overgrowth and dysbiosis. The reason chasing an anti-candida diet without testing moves you in circles.

Elevated calprotectin. A signal of gut inflammation, often present in women with IBD, Crohn's, colitis, and women with no formal diagnosis.

Elevated zonulin. A marker of intestinal permeability. The pattern we see after rounds of antibiotics, sinus infections, UTIs, birth control, and high stress.

Why this matters before a donor egg decision:

H. pylori impairs iron absorption. Ferritin reads low or low-normal. The clinic says iron is fine because the lab range starts around 15. The fertility-optimized range is closer to 50. Iron is foundational to egg quality. The oxygen carrying capacity to your follicles depends on it.

B12 affects methylation, the process your body uses to produce the co-factors needed for egg maturation.

Zinc affects ovulation and progesterone production.

Chronic gut inflammation affects ovarian response to stimulation, implantation, and miscarriage risk.

When your clinic looks at a canceled cycle, arrested embryos, or a failed transfer and recommends donor eggs, they are responding to the outcome. They are not asking what is driving the outcome.

This episode is for the woman sitting with a donor egg recommendation who is not ready to agree before she understands what was actually evaluated.
