🎙️ Fertile-ish — Season 2, Episode 3:
“Lining Check: Not Thick Enough”
Episode Overview
In this week’s episode of Fertile-ish, Laura and Brandis dive deep into one of the most common — and frustrating — fertility concerns: a thin endometrial lining. Whether you’ve had a cancelled transfer, are anxiously waiting for that “trilaminar” ultrasound report, or just trying to understand why your lining won’t thicken — this episode breaks down the science, the causes, and the real-life stories behind the numbers.
They’ll answer questions like:
What is a healthy lining thickness?
Why does “trilaminar” matter more than just the millimeters?
Can you still get pregnant with a thin lining?
And what can you actually do to help thicken it?
What You’ll Learn
đź’ˇ Anatomy Refresher:
Laura and Brandis explain the layers of the uterus — the serosa, myometrium, and endometrium — and why only the innermost layer (the one that sheds each month) really matters for implantation.
đź©ş Lining Goals & Measurements:
For frozen transfers: ideal lining ≥ 7mm and trilaminar
For fresh cycles: ≥ 8mm and trilaminar
Why measurement consistency (same sonographer, same technique) is key
And why organization (that three-layer trilaminar look) can matter more than pure thickness
đź’Š Common Causes of Thin Lining:
Hormonal birth control and prolonged progesterone exposure (like Depo-Provera or Mirena)
Scar tissue and Asherman’s syndrome from D&C, C-section, or retained placenta
Uterine abnormalities (polyps, fibroids, septum)
Long-term suppression of ovulation or endometrial regeneration issues
🧬 Solutions & Treatment Options:
Estrogen therapy (oral, vaginal, patch, or injectable)
Sildenafil (Viagra) to boost blood flow
PRP or Neupogen washes
Vitamin E supplementation
Switching to a natural or modified natural protocol if your body responds better to its own estrogen
Real Talk: Why Every Case Is Different:
From Facebook group myths to “what worked for her” advice, Laura and Brandis explain why fertility protocols can’t be copy-pasted. Even patients with identical labs may respond completely differently. Your baseline lining, hormone response, and surgical history all shape your protocol — and no single “magic number” applies to everyone.
Patient-to-Patient Tips:
✨ Advocate for Yourself: Ask why your provider recommends certain meds, protocols, or tests.
🩻 Don’t Skip the SHG or Hysteroscopy: It’s quick, simple, and can reveal polyps, fibroids, or scar tissue that may be silently affecting implantation.
💗 Remember: Thickness isn’t everything. A 6mm trilaminar lining might be more promising than an 8mm that’s disorganized.
The Fertile-ish Takeaway:
A thin lining doesn’t mean it’s the end of your fertility journey — it’s just another piece of the puzzle. The key is understanding your baseline, working closely with your team, and staying proactive about testing and timing.
