Report No. 90
1. Impotence, antecedent and perpetual, whether on the part of the man or the woman, whether known to the other party or not, whether absolute or relative, invalidates marriage by the law of nature itself.
2. If the impediment of impotence is doubtful either in law or in fact, the marriage is not to be hindered.
3. Sterility neither invalidates marriage nor renders it illicit.
