A few commonly known contraceptive methods are-
- Condoms- Even being the most common contraceptives, these are not fully sperm-proof thus are often used with a combination with other methods like anti-sperm-gels etc.
- Early withdraw- Though it is not a reliable method, still it is highly used by couples. Before the ejaculation, the penis is withdrawn from the vagina thus preventing the discharge of semen. But the pre-ejaculation fluid may contain sperms.
- Safe days- It is yet another common but highly unreliable contraception method. In a regular 28 days cycle, fertility is highest from 11th-17th days (ovulation). Thus it is believed that 5 days prior and 5 days post periods are safer.
- Contraceptive injections- These injections releases progesterone. It stops the ovulation & thickens the mucus around the cervix making it difficult for the sperm to get to the uterus. One shot of the injection can last up to 3 months.
- Implants- It is a 4-inch flexible rod which is implanted in the upper arm. It releases progesterone. It stops the ovulation & thickens the mucus around the cervix. An implant is effective for up to 5 years with a success rate of 99%.
- I-Pill- In case of unprotected sex, an I-pill can effectively prevent pregnancy even after two days of the intercourse. It mimics the natural hormones and prevents pregnancy. But it must be used in emergency only.
