If you are asking about a contraceptive that is used for both men and women, there really is not one. There are such things as “female condoms” but they are not the same thing as male condoms. I suppose that you could say that both the male and female are using the same method when they employ the rhythm method or coitus interruptus.
If you are asking for a list of all contraceptive methods for either men or women, here is a list of some of the most common.
- Rhythm method. In this method, the couple only has sex on days when the woman is not fertile. The appropriate days can be difficult to determine and the method is not very reliable.
- Male condom. A sheath worn over the penis to stop semen from entering the woman.
- Diaphragm. A cap worn over the cervix to prevent sperm from entering the uterus.
- Spermicidal gel. This is typically used with either a condom or a diaphragm.
- IUD. A device that is inserted into the uterus to prevent implantation of a fertilized egg.
- Hormonal contraceptives. These include oral contraceptives, patches, and implants. They all work by preventing ovulation.
- Surgical contraception. This includes vasectomies for men and tubal ligations for women. The former ensures that no sperm reach the penis and therefore no sperm are ejaculated. The latter prevents eggs from traveling down the fallopian tubes to the uterus.
These are the most important contraceptive techniques or devices.
