| titleOfInvention | Contraceptive methods and delivery systems therefore |
| abstract | Contraceptive methods for live animals (including humans) where a cap or disc (10) based on cellular material forms an inert carrier matrix to support contraceptive preparations, the cap or disc (10) being able to engage with the external bone of the cervical canal. The contraceptive preparation containing bivalent or trivalent metal cations and N-ascorbic acid and / or neuraminidase causes the cervical mucus coming into contact with the dose to pass from an open cell structure found in the middle of the cycle of the period menstrual to a closed cell structure forming an impenetrable barrier for sperm. This contraceptive preparation may also include asialoglycoprotein serving as an acceptor for sialic acid of the sperm in order to prevent the penetration and fertilization of the ova by the sperm. These preparations have another contraceptive property: they can be spermotoxic, causing the reformation of the seminal plasma to trap sperm, causing their death due to the acidity of the vagina (16). |
