Effective contraceptive methods can enable couples to have family planning and eliminate anxiety in sexual life. However, having contraceptive methods does not mean that contraception is successful and may fail, which is why so many people are recruiting. It is not not paying attention but it is not successful! The main reasons for its failure are as follows:
Contraceptive failure, which is the reason?
1, contraceptives:
1 missed clothes, late service or drug fragmentation, dissolution, so that the drug dose is insufficient;
2 high fever or severe diarrhea, vomiting, will affect the absorption of drugs;
3 At the same time taking such drugs as rifampicin, chloramphenicol, carbenicillin, chlordiazepoxide, and other drugs will reduce the active ingredient of the pill.
2, condoms:
1 The type of condom used is incorrect. It may be too large to fall off in the vagina. The size may squeezing the sleeve and losing the contraceptive effect.
2 Use damaged or contaminated latex condoms that have been stored for too long;
3 Some people only use condoms before ejaculation, which can also lead to pregnancy. Because of sexual excitement, the male genitalia secretes some secretions containing a small amount of sperm and flows into the vagina;
4 Before use, the air in the frontal capsule was not squeezed out, and the pressure in the sleeve was increased after ejaculation, and the sleeve burst and the semen overflowed;
5 After ejaculation, the penis and the condom were not extracted in time before the penis was not softened. After the penis was softened, the semen returned from the penis and the condom to the vagina.
6 After ejaculation, the penis slips into the vagina when the penis is pulled out, causing semen to spill into the vagina.
