Background and Aim: The rule of “prohibition of two seminal fluids in one uterus” plays a critical role in analyzing jurisprudential rulings related to modern medical technologies, particularly in fertility treatments and infertility solutions. This article examines the application of this rule to resolve novel medical dilemmas, aiming to clarify its implications for contemporary ethical and legal challenges. Materials and Methods: In this descriptive-analytical article, first, we examine the sources and jurisprudential texts, and then, by analyzing practical and applied examples, we attempt to explain the role of the rule "prohibition of two seminal fluids in one uterus" in solving emerging medical problems. Conclusion: When modern fertility technologies result in the mixing of two seminal fluids, the prohibition derived from the rule “prohibition of two seminal fluids in one uterus” extends to such practices. This prohibition applies to three key domains: 1) Assisted Reproductive Technologies (ART): Case 1: Using sperm from a unrelated male (Namahram) to impregnate a woman whose husband is infertile. Case 2: Surrogacy involving a married woman’s uterus. 2) Genetic Editing: Utilizing sperm from another male in genetic modification procedures. 3) Multiple Embryo Implantations: Implanting a second embryo into a pregnant woman, particularly when the embryo belongs to another couple (known as “double pregnancy”). In all these cases, “prohibition of two seminal fluids in one uterus” rule serves as a jurisprudential framework to address ethical complexities in modern medicine.
