British condom maker Futura Medical Plc said on Thursday that results of a study showed its new condom helped men have firmer and bigger erections, as well as a longer-lasting sexual experience.

Shares in the company, which specialises in sexual healthcare and pain relief, rose 14.5 per cent to 59.25 pence on hopes the condom, which will be marketed by Durex condom-maker SSL International, could go on sale next year.

Futura said the study of 108 healthy couples showed its CSD500 condom helped men to get a firmer erection compared with a standard condom, increased penis size and made the sexual experience last longer, delivering statistically significant results.
