Women have three types of orgasm - avalanche, volcano and wave, read more

Women experience three types of orgasm-a wave, a volcano, or an avalanche, according to the movement of pelvic floor muscles when they climax, a new study has revealed.

The study by Charles University in Prague, Czech Republic, revealed that the pelvic floor muscles of female volunteers predominantly showed one of three patterns when they climaxed.

As part of the study, 54 women used a Bluetooth-connected vibrator, called the Lioness. It detected the force of pelvic floor contractions in two sensors on its sides and sends the data to a secure internet server.

The volunteers were instructed to self-stimulate to one orgasm and then turn the device off two minutes after orgasm was achieved. This was then repeated over several days. The data from the devices was analysed later, according to reports.

Most of the participants have experienced the 'wave' pattern, with 26 out of the 54 women experienced this type, followed by avalanche in 17 and volcanoes were experienced by 11 of them.

"The names refer to the way the pelvic floor movements appeared during the build-up to orgasm and the release of tension at orgasm. The wave looks like undulations or successive contractions of tension and release at orgasm. The avalanche rides on a higher pelvic floor tension with contractions that lower the tension downward during orgasm. The volcano rides on a lower pelvic floor tension but then explodes into tension and release during orgasm," lead researcher James Pfaus, a professor of neuroscience at the University, was quoted as saying by media outlets.

He added that no one style is better or worse than another. The findings were published in the Journal of Sexual Medicine. The researchers now want to focus on the way the three orgasm styles are experienced by women, reports said.

"We are doing a long-term study of women using the Lioness to see how these different patterns are experienced subjectively as orgasms, as levels of pleasure, where the stimulation that induces them largely comes from," Professor Pfaus told media.
