What Method of Contraception Either Kills Sperm or Prevents Them from Entering the Cervical Os?

Understanding Contraception Methods

When it comes to contraception, there are various methods available to prevent pregnancy. These methods can be broadly categorized into two types: barrier methods and non-barrier methods. Barrier methods, as the name suggests, create a physical barrier between the sperm and the egg, preventing fertilization from occurring. Non-barrier methods, on the other hand, work by either killing the sperm or preventing them from entering the cervical os (the opening of the cervix).

Barrier Methods

Barrier methods are a popular choice for contraception, and they work by creating a physical barrier between the sperm and the egg. These methods include:

Condoms: Condoms are a type of barrier method that cover the penis during sexual intercourse. They are made of latex or other materials and are designed to prevent sperm from entering the vagina.
Diaphragms: Diaphragms are a type of barrier method that are inserted into the vagina before sexual intercourse. They are dome-shaped and cover the cervix, preventing sperm from entering the uterus.
Cervical caps: Cervical caps are a type of barrier method that are inserted into the vagina before sexual intercourse. They are smaller than diaphragms and are designed to cover the cervix.

Non-Barrier Methods

Non-barrier methods, on the other hand, work by either killing the sperm or preventing them from entering the cervical os. These methods include:

Hormonal contraceptives: Hormonal contraceptives, such as the pill, patch, and ring, work by releasing hormones that prevent ovulation. They do not kill sperm or prevent them from entering the cervical os.
Intrauterine devices (IUDs): IUDs are a type of non-barrier method that are inserted into the uterus. They release hormones that prevent ovulation or kill sperm, preventing fertilization from occurring.
Spermicides: Spermicides are a type of non-barrier method that are applied to the vagina before sexual intercourse. They kill sperm, preventing fertilization from occurring.

Answer to the Question

Based on the information provided, the correct answer to the question is A. Barrier methods. Barrier methods, such as condoms, diaphragms, and cervical caps, create a physical barrier between the sperm and the egg, preventing fertilization from occurring. They either kill sperm or prevent them from entering the cervical os.

Conclusion

In conclusion, there are various methods of contraception available, each with its own unique mechanism of action. Barrier methods create a physical barrier between the sperm and the egg, while non-barrier methods work by either killing the sperm or preventing them from entering the cervical os. Understanding the different types of contraception methods is essential for making informed decisions about reproductive health.
