Reproductive immunology deals with phenomena and observations, as well as hypotheses regarding immunological processes in reproduction.
This fact simply did not fit the knowledge of the time about immunological processes and the rejection of foreign antigens. Since then, reproductive
immunology has developed into a distinct area of research in reproductive medicine. Researchers are most interested in understanding the processes that maintain the immunological balance, which is a critical factor for the healthy progression of pregnancy. Identifying immunological processes in a healthy pregnancy is in turn a basic requirement for understanding pathological processes. The resulting insights enable clinicians to develop therapeutic approaches for disrupted pregnancies.
