We are working on a clinical study "Relationship between regulatory T cell subsets and pregnancy in infertility patients".
Patients who can cooperate with this study can receive blood tests related to infertility and recurrent pregnancy loss free of charge.
If you plan to transfer thawed embryos, please join us.
Regulatory T cells (Tregs) are lymphocytes that control immune tolerance. To establish a pregnancy, immune suppression (immune tolerance) is required to accept a fetus into the mother, and Tregs are thought to play an important role in this. This study examines Treg variability during the thawed embryo transfer cycle. At the same time, we will carry out tests for recurrent miscarriage, aiming to clarify the pathophysiology of infertility and recurrent miscarriage and to take a new approach to treatment.
During the hormone replacement cycle, blood is collected. In addition to Treg measurement, hormone levels, copper / zinc (affects implantation), and blood coagulation systems (related to recurrent pregnancy loss) are examined.
Please provide about 10 to 20 ml of blood on the day of embryo transfer, the day of pregnancy judgment, and if you become pregnant, at the time of the initial pregnancy test (around 9 weeks of pregnancy).
Patients who meet the following conditions are eligible.
※During the research period, infertility treatments (fresh embryo transfer, artificial insemination, timing method, etc.) that deviate from the research plan cannot be performed. If the research protocol cannot be completed due to the patient's convenience, the examination fee will be charged.
If you would like to participate, please contact the staff.
The deadline will be on a first-come, first-served basis, acceptance ending as soon as the capacity is reached.
In addition, please note that you may not be able to participate if you do not meet the participation criteria.
