With the development that humanity witnesses in the accurate medical devices, which reveals and diagnoses what is
happening inside the human body like knowing the gender, the number and other things concerned with safety and growth of the fetus inside
mother's uterus. We can also depend on the devices after the first three months to know the gender and the number of the embryos, and
accordingly we can know the portion of inheritance that should be kept for the probable fetus without a need to suppose being male or
female, single or twins. This research aims to show how to solve the questions of the exposed pregnancy and the remaining hypotheses, using
descriptive, analytical methodology by dividing the research into: Introduction showing the pregnancy definition and conditions of its
inheritance, then indication of inheritance if male or female and nature of inheritance, A multiple, symmetrical, different, and conjoined
embryo pregnancy. The research has come to the following conclusion: The scholar's hypotheses in solving pregnancy issues, even if The
hypothesis of jurists in solving pregnancy issues, even if we may drop some of it because of what the medical device reveals, however, the
assumption of giving birth to alive fetus or a dead one is a core, fixed hypothesis that medical devices cannot get rid of it No matter how
accurate it is, as life and death only determined (controlled) by Allah. These death and life hypotheses increase with multiple embryos, as the
higher number of twins, the higher number of hypotheses. Moreover, we can depend on medical devices without hesitation once pregnancy
passed the sixth month whether it is single or even multiple, but if single, we will depend on the device at the end of third month. The
research recommends to link doctrinal research to reality and focus on practical issues.
