U.S., Feb. 15 -- ClinicalTrials.gov registry received information related to the study (NCT06826365) titled 'Immune Cell Populations in the Endometrium' on Feb. 08.
Brief Summary: Specialized immunological studies in the diagnostics of idiopathic infertility and recurrent miscarriages have limited applicability, as the role of the immune system in these conditions is not thoroughly understood. In ovulatory cycles, changes occur in the populations of uterine lymphocytes, which may influence the receptivity of the endometrium and the implantation of the embryo. Particularly notable are the changes in natural killer (NK) cells, which reach their peak during the luteal phase and regulate the invasion of the trophoblast. The dominant NK cells e...
