Zimbabwean police believe there is a nationwide syndicate of women raping men, possibly to use their semen for use in rituals that claim to make people wealthy.
It has taken more than a year for any arrests to be made, and on Monday three women are to go on trial in the capital, Harare, over the allegations which have shocked the country.
One alleged victim, who wished to remain anonymous, gave an account on national television in July of his experience which happened after he was offered a lift by a group of three women in Harare.
“One of the women threw water in my face and they injected me with something that gave me a strong sexual desire,” he said.
“They stopped the car and made me have sex with each of them several times, using condoms.
“When they had finished they left me in the bush totally naked.
“Some people gathering grass helped me by calling the police, who took me to hospital to deal with the effects of this drug that I had been given, as the urge to have sex was still there.”
The women due in court have been charged on 17 counts of aggravated indecent assault – as Zimbabwean law does not recognise the act of a woman raping a man.
They were detained earlier this month in the central town of Gweru, 275km (170 miles) south-west of Harare, after officers found 31 used condoms in the car that they were travelling in.
