Levothyroxine for IVF in women with mild thyroid issues
Part of Hormones & metabolism, Women’s health & pregnancy clinical trials.
This study tests whether taking levothyroxine (a thyroid hormone medication) before IVF or ICSI with frozen embryo transfer improves pregnancy rates in women with subclinical hypothyroidism (a mild thyroid condition). It aims to see if this treatment helps women like you have a better chance of getting pregnant.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are a woman between 18 and 45 years old.
- You have subclinical hypothyroidism (a slightly high TSH level, between 4.2 and 10, with normal thyroid hormones).
- You are planning to have IVF or ICSI with a frozen embryo transfer.
- You do not have overt hypothyroidism (very high TSH or very low thyroid hormones).
- You have not taken thyroid-affecting medications (like levothyroxine, amiodarone, methimazole, or propylthiouracil) in the past month.

This trial tests whether taking prednisone (a steroid) and aspirin (a blood thinner) before embryo transfer improves pregnancy rates in women with thyroid antibodies. If you have these antibodies and are doing IVF, this could help reduce inflammation and improve your chances.
This trial tests whether adding a low-dose thyroid hormone (levothyroxine) to the standard fertility treatment letrozole improves pregnancy rates in women with both PCOS and mild hypothyroidism. It may help if you have trouble getting pregnant and have these two conditions.
This study looks at how follitropin delta is used in real clinics to help women stimulate eggs for IVF or ICSI. It may help doctors fine-tune dosing by comparing outcomes in everyday practice.
This study tests whether adding a hormone called r-hLH to standard IVF treatment helps women aged 35 to 40 produce better eggs and improve their chances of pregnancy. It is for women who are on their first or second cycle of assisted reproduction.
This trial tests a fertility drug called follitropin delta for women undergoing IVF. It checks if using this drug with a specific hormone-lowering protocol helps produce eggs for fertilisation.
This trial tests whether a thyroid hormone medication (levothyroxine) can improve heart function in children who have slightly high TSH levels but normal thyroid hormones. It may help children aged 4 to 15 with subclinical hypothyroidism.
