“Whatever the grounds,abortion is generally prohibited unless the delivery of the baby poses a direct threat to the life of the mother.The most obvious case is where the mother might die as a result of the birth This category is explicitly recognized in the Mishna. See Oholot 7:6..Halacha also recognizes that a threat to life may be more than physical; psychological stress and anxiety may be life threatening to either the mother or other members of the family and where such indirect pikuach nefesh(danger to life) exists,abortion may be justified if other alternatives such as adoption are insufficient to alleviate the danger.Assume,for example,that a child was conceived through rape or incest.According to most views,that fact standing alone would not justify abortion.The fetus is still at least a potential life that ought to be brought to fruition in the absence of a threat to maternal survival.However,halacha also understands that the psychological trauma arising out of the circumstances of conception may be so devastating as to constitute such a threat at least in some cases though it may not be so in others.In short,halacha does not have an automatic or categorical rape or incest exception;any dispensation must be folded into the general rule of pikuach nefesh.”

“QUESTION TWO::If a baby is determined in utero to have a life threatening disease that may allow them to live only after a few months, is it permissible to terminate the pregnancy?
ANSWER TWO:.The answer in brief:,Jewish law will generally not permit abortion because of a diagnosis that the fetus suffers from a genetic condition which will result in its early death.A number of views would allow early-term abortion within 40 days of conception(a time frame that may be too early for diagnosis through amniocentesis or ultrasound)”
