Lining
Plain-English guide for patients and families.
A persistently thin lining reduces implantation odds. Causes include prior surgery, infection, blood flow, prior radiation, or idiopathic factors. Management uses estrogen dosing, vaginal vs oral routes, G-CSF or PRP in research/select protocols, hysteroscopy for missed adhesions, and sometimes delaying transfer.
Measurement
Ultrasound thickness in mm varies by cycle day and plane — follow your centre's protocol rather than a single internet number.
AI Information
EducationalEndometrial thickness is a key factor in IVF success — most clinics aim for ≥7–8mm with a trilaminar pattern before embryo transfer. A persistently thin endometrium (<7mm despite adequate estrogen) is challenging and requires systematic investigation. While standard approaches include extended estrogen, route changes, and hysteroscopy, newer adjuncts like intrauterine PRP and G-CSF are being explored.
Key Points
- Most clinics target endometrial thickness of ≥7–8mm with a trilaminar (triple-line) pattern on ultrasound.
- Pregnancy can occur with thinner linings, but implantation rates are reduced — there is no absolute cut-off.
- Causes include Asherman's syndrome, prior endometrial instrumentation, clomiphene use, radiation, and inadequate blood flow.
- Extended estrogen protocols, vaginal sildenafil, and pentoxifylline/vitamin E are among adjuncts used in practice.
- Intrauterine PRP injection is an emerging intervention showing promise in small studies for refractory thin endometrium.
Who Should Know This?
Women with persistently thin lining during FET preparation, those with a history of D&C or uterine surgery, patients with failed IVF despite good embryos, and anyone whose transfer has been cancelled due to thin lining.
