(CNN) -- They already have enough sons to field a baseball team. And if their streak continues, they'll be able to add a basketball team, too.
Kateri and Jay Schwandt, a Michigan couple with 12 sons and no daughters, welcomed their 13th child Wednesday morning.
And guess what? It's another boy.
"Why change things up now?" Kateri Schwandt told reporters in October, expressing her preference for a son. "At this point, at this stage in the game, a little girl, we'd have to relearn everything."
All the children were conceived naturally, according to the Detroit Free Press.
Jay Schwandt confirmed to CNN affiliate WXMI that the baby was born healthy at 9:06 a.m. He and his wife have not decided on a name for the boy.
The odds of the couple having 13 sons in a row is about 1 in 8,000.
Of course, that's not as unlikely as, say, winning the Mega Millions jackpot (odds: 1 in 175,711,536). But it's awfully close to your risk of being struck by lightning.
Here are some related odds:
Odds of having a boy: 1 in 2
Odds of having a girl: 1 in 2
Odds of having natural identical twins: About 1 in 250
Odds of having conjoined twins: About 1 in 200,000
Odds of twins giving birth on the same day: 1 in 400,000
Odds of having natural triplets: About 1 in 8,100
Odds of having natural quadruplets: About 1 in 700,000
