23.

Explanation:

Unlike all the other cells in a human body which are diploid, human sex cells are haploid.

That means that both sperm cells and ova are haploid; containing only 23 chromosomes.

In a diploid cell, the 46 chromosomes that a human cell contains exist in 23 pairs.

When the sex cells are being formed, they take only one of each pair, ending up with 23 unpaired chromosomes each. That is how a human embryo contains 46 chromosomes, 23 from each parent.
