Clinical Trial Summary

Fallopian tubes participate in the incorporation of gametes and embryos into the endometrial cavity. It also provides an optimal environment for flattening and early embryonic development. Tubal pathologies can cause both primary and secondary infertility. This condition has been associated with overt and subclinical hypothyroidism. However, the effects of hypothyroidism on tubal activity are not fully known. Although a few animal experiment studies on this subject have been published, there is no study on this subject in the literature. Demonstrating that epithelial and smooth muscle cells of rat fallopian tubes express thyroid receptors in animal experiments showed that fallopian tubes are targets for thyroid hormones. Again, in an animal experiment study, it was revealed that thyroid hormones have an important control on glycogen and lipid storage, lipid signaling and lymphocyte infiltration, which have an important role in maintaining the microenvironment in the rat fallopian tubes. This microenvironment is necessary for fertilization, sperm capacitation and gamete development. In another animal experimental study, it was thought that changes in the size of the epithelium of the fallopian tubes and cell metabolism in hypothyroid rabbits may affect oviductal activity and reproductive functions. An ectopic pregnancy is defined as a pregnancy implanted outside of the uterus. Ectopic pregnancy >98% implants in the fallopian tube. The etiology of ectopic pregnancy is unclear, but tubal implantation is probably due to impaired embryo-tubal transport. This is due to changes in the tubal environment. Based on this information, we aim to determine the possible relationship between hypothyroidism and ectopic pregnancy in humans in our study.

Description:

Our aim in this study is to determine the possible relationship between hypothyroidism and ectopic pregnancy in humans. For this purpose, 40 patients with a diagnosis of ectopic pregnancy and 40 patients with diagnosis of early pregnancy followed in Siirt Training and Research Hospital between 30 June 2022 and 30 October 2022 will be included in the study. The patient's age, pregnancy history, medical history and laboratory findings (TSH, sT3, sT4, TT3, TT4, thryoglobulin , Anti-Peroxidase Antibody, Anti-thryoglobulin Antibody, TSH receptors antibody ) will be recorded. In the light of the information gathered, it will be tried to determine whether there is a relationship between thyroid dysfunctions and ectopic pregnancy.
