MICE have been used to make human sperm, researchers say.
The discovery shows the animals can be used as surrogate sperm producers for men who cannot produce viable sperm of their own.
The research could, however, prove controversial because it gives a separate species an intimate role in human reproduction.
The research could “prove controversial”, eh? Geez. You don’t say.
Tanya wonders: Is there a shortage of human sperm?
Either way, the story reminded me of this scene (1:38 into the clip).
Imagine, this keeps up and the next generation won’t find that joke funny.
