It was Henson's first Wales start in more than a year, and he did enough at inside centre to suggest new coach Warren Gatland need look no further for a long-term number 12.
"It is great being a father - it is the best thing that has ever happened to me," Henson said.
"I put a lot on myself in terms of training and thinking about the game a lot, and then suddenly you realise something else comes first, which is the baby.
"I think that might help me a lot in terms of relaxing away from the game and chilling out a bit more.
"But I enjoyed the game, it was nice to get the ball in my hands. We had our fair share of the game."
Henson's midfield combination with Ospreys colleague James Hook augured well for future tests, yet Wales finished a distant second best in many key areas.
They could not match the Springboks' revered power game, while an often feeble defensive display provided proof - if any was required - of how Gatland must move heaven and earth to get Wasps' Shaun Edwards on board as part of his coaching staff.
South Africa scored five tries - Jaque Fourie (two), JP Pietersen, Juan Smith and impressive number eight debutant Ryan Kankowski touched down - and it would undoubtedly have been more had wing magician Bryan Habana seen possession on a regular basis.
