2,193. A Perforation

Hilchos Issurei Biah 16:5

If the male organ is perforated below the tip, the man may marry in. If the tip is perforated so that semen comes out the hole, the man is disqualified; if the hole closes, he becomes able to marry in again. If the member is perforated below the tip with the piece above in the middle of corona, he is disqualified because the whole tip needs to be intact.

Hilchos Issurei Biah 16:6

If the vas deferens gets blocked so that semen emerges from the urethra, the man is disqualified.
