Yes, but it is abnormal. In men, elevated hCG can be a marker for testicular cancers or other germ cell tumors.

Learning
Memory Aids
Mnemonic
Think: CHORIO (as in chorion, part of the placenta) + NIC (attached to) + GONADO (referring to gonads/ovaries) + TROPIN (a substance that stimulates or 'turns toward' something). So, it's the placenta's hormone that 'turns toward' stimulating the ovaries.
Conceptual Metaphor
A MESSENGER or SIGNAL from the pregnancy to the mother's body.
