Vitamin D study to improve uterine lining for pregnancy
Treatments studied
Part of Hormones & metabolism, Women’s health & pregnancy clinical trials.
This trial tests whether taking vitamin D can improve the uterine lining’s readiness for pregnancy in women who struggle to conceive. It compares different groups of infertile patients to see who may benefit and to monitor for safety.
Summary written for real people, not researchers, by Clin2.

This Phase 2 study tests whether vitamin D can improve hormone balance and infertility-related problems in people with PCOS who have low vitamin D. You may be able to join if you’re between 18 and 36, have primary infertility, and meet specific PCOS and vitamin D blood test levels.
This study looks at whether blood-thinning medication can improve the chance of pregnancy in women who have trouble conceiving. It focuses on how the medication affects the lining of the womb and its ability to accept an embryo.
This trial studies whether taking vitamin D can improve ovulation (the release of an egg) in people with PCOS who have long, irregular menstrual cycles. It may help some participants have more regular ovulation and cycle timing, but you would be monitored with vaginal ultrasound and blood tests.
This study looks at possible “background causes” of chronic inflammation of the uterus lining in women who struggle to get pregnant or have repeated miscarriages. It may help doctors better understand what factors contribute to infertility so care can be more targeted.
This study looks at how vitamin D levels affect pregnancy success after a frozen embryo transfer. If you are a woman planning this procedure at Fakih IVF, you may be able to join to help researchers understand the link between vitamin D and pregnancy outcomes.
This trial tests whether vitamin D injections can help females with polycystic ovary syndrome (PCOS) who also have low vitamin D levels. Participants will receive the injection and be monitored for changes in their condition.
