In this casereport, we wanted to observe a whole process of a patient with secondary infertility and investigate the causes andwhether there are any solutions for it.Case Report:A 41-year-old female patient presented to the clinic with the complaint of not being able to get pregnant.First thoughts about the patient were focused on infertility however, she had a child before. Therefore, furtherinvestigations were needed. After the investigations, she was diagnosed with secondary infertility because no rationalreasons were able to clarify her disease.Conclusion: Nowadays, secondary infertility is still a major health problem and no medications or treatments areenough to resolve this problem. The most common theory is the H-Y antigen hypothesis, but still, there is not enoughevidence for this theory to be proven.eninfo:eu-repo/semantics/openAccessInfertilitypregnancyimmune systemArticle537678481902
