Disposable Penis!

Have you ever heard of disposable penis? It exists.


It is Chromodoris reticulata. It loses but re-grows and re-uses its penis. You don’t believe me? Please read it.

The little sea slugs are “simultaneous hermaphrodites”, they have both male and female sexual organs and can use them both at the same time.

Sea slugs are not the only animal who lose their penis. Orb weaver spiders also lose their penis after sex. They lose penis, but it grows again. Why do they have to lose penis if it has to regrow? A very valid question. Scientists say:

‘In the first act of copulation the penis may be used to remove any sperm left by any competitors that its partner has mated with.
With the first penis and the rival sperm then abandoned – the second penis can be used to inject the sea slug with another dose of its own sperm, ensuring that their genes are the ones that are passed on.’

What if humans had disposable penis? Most likely men will not have disposable penis until women seriously sleep around. How much I wish to see men’s disposable penis!
