Three teenage boys and a man have been charged with allegedly drugging and raping a young woman, then leaving her in a southern Sydney street three months ago.

On a Saturday night in October, it's alleged the 18-year-old woman met a 17-year-old boy known to her at a Lugarno pizza shop, with the pair then meeting up with friends of the boy - another 17-year-old , a 15-year-old and a man, 38.

It's alleged the woman was given an unknown substance and while under the influence, was sexually assaulted several times.

She was then dropped off in a Riverwood street several suburbs away and found by a passer-by.

The four males were arrested on Thursday and all charged with aggravated sexual assault in company and refused bail.

The teens will face a children's court on Friday with the man due to face Liverpool Court.
