The former teacher and journalist stands accused of raping or sexually abusing men between 1983 and 2019.
He formally faces six charges of indecent assault and one of sexual assault.
Breytenbach is out on bail, and on Monday his case was postponed to 29 September.
This to allow for “further particulars and consultation”, which involves the exchange of legal correspondence between the prosecution and defence legal teams before the case will proceed.
Breytenbach arrived at the Cape Town Regional Court in the Cape Town central business district shortly before 9am, wearing a black suit, and appeared within 30 minutes in Court I.
The proceedings only lasted several minutes, before he was dismissed and warned to appear punctually on the new court date.
Breytenbach declined an opportunity to comment on the case.
