My uterine lining is thin and my transfer got postponed. What can be done for a thin endometrium?

The endometrium is the lining of the uterus where an embryo implants. Many doctors prefer a lining of around 7 mm or more before a transfer, though pregnancies do happen with thinner linings and the pattern on scan also matters. Postponing a transfer when the lining isn't ready is a common, careful decision rather than a failure. Thin lining can be linked to low estrogen levels, how the body responds to the medication protocol, reduced blood flow to the uterus, past infections (including genital tuberculosis, which is important to rule out in India), or scarring from previous procedures like D&C (Asherman syndrome). Sometimes no clear cause is found. Depending on the cause, doctors may try adjusting the dose, route or duration of estrogen, changing to a natural-cycle or ovulation-based transfer, or doing a hysteroscopy to look inside the uterus and treat scar tissue or polyps. Various additional treatments are sometimes offered but the evidence for many of them is limited, so it's reasonable to ask how strong the evidence is before agreeing to one. Discuss the likely cause and a plan for the next cycle with your fertility specialist. Seek advice sooner if you have very light or absent periods, pelvic pain, or a history of infection or uterine surgery.
