The man
This can also be translated here as "the human being" or "Adam" (UDB).
had marital relations
"had sex with." Your language may have a way of saying this politely. Some languages say "knew" or "slept with." (See: rc://en/ta/man/translate/figs-euphemism).
I have produced a man
The word for "man" typically describes an adult male, rather than a baby or child. If that would cause confusion, it could be translated as "manchild" or "boy" or "baby boy" or "son."
Cain
Translators may want to include a footnote that says "The name Cain sounds like the Hebrew word that means 'produce.' Eve named him Cain because she produced him." (See: rc://en/ta/man/translate/figs-explicit)
Then she gave birth
We do not know how much time passed between the births of Cain and Abel. They may have been twins, or Abel may have been born after Eve became pregnant again. If possible, use an expression that does not tell how much time passed.
