The barrier method
Barrier methods, such as condoms and diaphragms, physically prevent sperm from reaching the egg by creating a barrier between the two. Spermicides are another type of contraceptive that work by immobilizing or killing sperm before they can reach and fertilize an egg.
Surgical methods of contraception include tubal ligation for women and vasectomy for men. Tubal ligation involves blocking or sealing the fallopian tubes to prevent eggs from reaching the uterus. Vasectomy involves cutting or blocking the tubes that carry sperm from the testicles. Both methods are considered permanent and highly effective forms of birth control.
The process of preventing the fertilization of eggs is called contraception. Contraceptive methods can include hormonal options (like birth control pills), barrier methods (such as condoms), intrauterine devices (IUDs), and surgical procedures (like sterilization). These methods aim to inhibit sperm from reaching the egg or prevent ovulation altogether.
Barrier methods like condoms prevent sperm from reaching the egg. Hormonal methods like birth control pills prevent ovulation, making it so there is no egg for sperm to fertilize. Intrauterine devices (IUDs) can also prevent sperm from reaching the egg or fertilized egg from implanting in the uterus.
Spermicides are a type of contraceptive that contain chemicals designed to immobilize or kill sperm, preventing them from reaching and fertilizing an egg. They are typically used in conjunction with barrier methods such as condoms or diaphragms to enhance their effectiveness. Spermicides are available in various forms, including gels, foams, creams, and suppositories.
The barrier method
Barrier contraceptive methods physically prevent sperm from reaching the egg, such as condoms and diaphragms. Chemical contraceptive methods, on the other hand, utilize hormones to prevent ovulation or change the cervical mucus to inhibit sperm movement, like birth control pills or patches.
A contraceptive method that physically blocks sperm from reaching the egg is a barrier method, such as a condom or diaphragm. These devices create a barrier that prevents sperm from entering the uterus and reaching the egg, therefore preventing fertilization.

The barrier method
Contraception by the 'barrier' method - such as a condom, or a diaphragm in the woman. Contrast this with phamaceutical methods, such as the Pill, or spermicides.
Vasalgel is a non-hormonal, long-acting contraceptive for men. It is a polymer gel injected into the vas deferens, blocking the passage of sperm while allowing other fluids to pass through. This prevents sperm from reaching the ejaculate, providing effective contraception.
Barrier methods such as condoms, diaphragms, and cervical caps create a physical barrier that prevents sperm from reaching the egg. Additionally, spermicides can also be used to immobilize and kill sperm before they can fertilize the egg.
Potential steps to target for male contraceptive development could include blocking sperm production (spermatogenesis), inhibiting sperm motility or preventing sperm from reaching the egg by interfering with the process of fertilization. Additionally, targeting the fusion of sperm and egg (sperm-egg binding) or inhibiting the release of enzymes that allow sperm to penetrate the egg could also be potential strategies.
Abortion methods should not be confused with methods to prevent pregnancy (contraceptive methods, including emergency contraception). Contraceptive methods work by preventing ovulation (the release of an egg) or by stopping the egg and sperm from meeting. Contraceptive methods, including emergency contraception, cannot be used to terminate or interrupt an established pregnancy. You can visit findmymethod.org to learn more about contraceptive methods.
