311

This number is a prime.

311 is the 64th prime number. The entire process from production to ejaculation of mature spermatozoa takes, on average, 64 days to complete. 311 is the standard gematria value of the Hebrew word איש ('iysh, pronounced, eesh), meaning, man or husband, who, according to Genesis 2:24 would “leave his father and mother, and cleave unto his wife: and they shall be one flesh.” Reference: D.
