Regarding ART, the positive view of medicine is challenged by the Jewish religious legal system (halakha) which has numerous laws regarding modesty, sexuality and verifiable lineage.

[3][4] Puah works with couples both by reviewing medical records and advising as to specific doctors and by finding solutions to problems of Jewish law raised by treatment procedures.

[citation needed] Due to fear of both human error[5][6] and intentional deception (as in the case of Cecil Jacobson) the majority of orthodox rabbis have ruled that Jewish law requires an outside supervisor present to monitor the procedure and storage of the genetic material.

An orthodox man or women must oversee all aspects of the in vitro fertilization (IVF) process, including sample washing, centrifugation, freezing and loading of pipettes.

[citation needed] In January 2010, Puah launched JewishFertility.org, an educational website giving information about the practical applications and interactions of Jewish law and fertility medicine.
