Is it true that a Jewish woman may not marry a man who did not have a Bris (Circumcision)?
It is not proper for a Jewish man to be uncircumcised, and he is supposed to have a Bris as soon as possible. It is not so much an issue of marriage, as much as it is an issue of just general life. A Jewish woman might not want to marry a man who is lacking this basic sign of Judaism.
There are rabbis in your area who can refer this person to the proper medical care to have this serious problem fixed, in a safe and relatively comfortable way. If you want any more information, let me know.
