And yes, the female immune system has a response to the invasive sperm.
The female doesn't just accept willy-nilly any willy-vanilly that comes her way.

Across all mammalian species, responses like this exist.
Professor Susan Suarez is a retired professor of biology at Cornell University.
She has a fish named after her, which is absolutely apt because she has spent most of her career studying little swimmers.
Here she is talking about bull sperm coming into contact with the reproductive tract of a female cow.
And yes, you, human, mammal, in the big family of mammals along with cows and mice, your body, or the body of your mother, has similar responses, sorting out good semen, modifying their immune response to facilitate implantation, or not.
