The chief prosecutor may ask for a new charge of mass rape to be made against Kadhafi, he said.
Moreno-Ocampo is expecting a decision soon from judges on his request for charges of crimes against humanity to be laid against the Libyan leader, his son Seif al-Islam and intelligence chief Abdullah al-Sanussi.
There are reports of hundreds of women being attacked in some areas of Libya, Moreno-Ocampo said. He claimed Kadhafi’s forces were buying containers of "Viagra-type" medicines “to enhance the possibility to rape women".
Kadhafi's regime had not previously been known for using rape as a weapon against political opponents and Moreno-Ocampo said he had to find evidence that the Libyan leader had given the order.
In March, Libyan woman, Iman al-Obeidi, made international headlines when she entered a Tripoli hotel and said she had been raped by Kadhafi troops. After escaping to Qatar she was deported to rebel-held Libya and is now resting at a refugee centre in Romania.
The Libyan government does not recognise the international court's jurisdiction.
