Almost 30 years after the intricate web of nerves inside the penis was plotted out, the same mapping has finally been completed for one of the least-studied organs in the human body – the clitoris.

As well as revealing the extent of the nerves that are crucial to orgasms, the work shows that some of what medics are learning about the anatomy of the clitoris is wrong, and could help prevent women who have pelvic operations from ending up with poorer sexual function.

The clitoris, responsible for sexual pleasure, is one of the least studied organs of the human body. Cultural taboo around female sexuality has held back scientific investigations and the clitoris did not even make it into standard anatomy textbooks until the 38th edition of Gray’s Anatomy was published in 1995.

“This is the first ever 3D map of the nerves within the glands of the clitoris,” said Lee. She is amazed it has taken so long, considering a similar level of knowledge regarding the penile gland was reached back in 1998, 28 years ago.
