Ross sparked outrage by suggesting that provocatively dressed women who go out unescorted were akin to a bank storing sacks of cash by the door.
He claimed that some victims had gone too far by leading men on.
Rosss comments were condemned by womens groups as provocative, crude and really horrible.
The presenter acknowledged that his words would be viewed as heresy by many who questioned whether women should ever be held responsible at all.
Yesterday Ross defended his comments, saying he had been quoting research in his book, and that he had been a champion of Victim Support for years.
But he later clarified: Womens dress is neither a contributor or excuse for assault.
In a serialisation of his new book, Ross said: We would laugh at a bank that stored sacks of cash by the front door. We would be aghast if an airport badly skimped on its security measures.
Our forebears might be astonished at how safe women are today given what throughout history would have been regarded as incitement.
Not even in the licentious days of Charles II in the 17th century was it acceptable for women to dress as provocatively as they have done in Western culture since the 1960s.
Equally, they would be baffled that girls are mostly unescorted, stay out late, often get profoundly drunk and sometimes openly kiss, grope or go to bed with one-night stands.
He claimed that half of all women who had unwilling penetrative sex do not think they have been raped, with victims believing they led him on, they went too far, it wasnt forcible, they didnt make themselves clear
He added that for them, rape isnt always rape, no matter how upsetting.
In a statement, Ross, 65, insisted that his book was serious, carefully researched and evidence-based, and described rape as one of the most defiling crimes.
He said: Far from attacking victims, the chapter explores why so few victims report rape, why so few prosecutions take place, and whether criminal courts are the best way of helping to deal with the appalling suffering caused by sex attacks.
For the record, lest it needs saying, and, as I make clear in the published extracts, anyone who suffers such a violating crime should be the centre of our concerns.
He said the book cited research that found many victims themselves do not regard what happened to them as rape, even though in law it plainly was.
Ross said it sickens and appals him that people could now assume he blames victims or belittle what they suffer.
