TL;DR
The induction of a local immunological response to semen by the woman has been attempted as a method of contraception and spermicidal agents in cervical mucus have been suggested.
Abstract
The significance of the cervix and its secretion, in relation to conception, varies with the species. By natural service, semen deposition in the pig and horse is intrauterine. This is also the site of artificial insemination in cattle even though the semen is deposited in the vagina at natural mating. In these species, therefore, the cervix is by-passed and the cervical mucus can be used only indirectly as an indicator of the stage of the cycle or of the hormonal state of the female. In contrast, in the sheep and in man the semen is deposited in the vagina. Furthermore, human semen is deposited in the female tract at times other than when fertilization can occur. The cervix in these species is involved in the process of conception. The physical and chemical properties of the cervical mucus

The γ1A present in saliva and colostrum exists largely in the form of higher polymers, the major component of which has a sedimentation coefficient of 11S, and its properties including the local production of a distinctive type of antibody separate it from the "systemic" system responsible for the production of circulating antibody.

Tests showed the uterine fluid-iodide-hydrogen peroxide system suspended spermatozoa was inhibited by catalase and by such low-molecular-weight compounds as azide reduced glutathione cysterine ergothioneine and ascorbic acid, which suggests that its sperm inhibitory effect is due to its perioxidase content.

The findings are interpreted to signify that while chlormadinone acetate administration might cause an increased hostility of the cervical mucus to sperm penetration and survival the contraceptive effect of this drug cannot be explained by cervical mucUS changes alone.
