9. Question: What is a mechanical barrier in pregnancy control?

Answer: A mechanical barrier in pregnancy control refers to physical devices used to prevent sperm from reaching the egg.

Explanation: Examples of mechanical barriers include condoms and diaphragms. These devices physically block the sperm from entering the uterus, thus preventing fertilization. Condoms are worn on the penis, while diaphragms are inserted into the vagina to cover the cervix. These methods are commonly used as contraceptive measures to reduce the risk of unwanted pregnancies.

10. Question: What are IUCDs in pregnancy control?

Answer: IUCDs (Intrauterine Contraceptive Devices) are small, T-shaped devices inserted into the uterus to prevent pregnancy.

Explanation: IUCDs work by altering the environment of the uterus, making it inhospitable for sperm and preventing fertilization. Some IUCDs also prevent the fertilized egg from implanting in the uterine wall. They are a long-term contraceptive option and are highly effective, with minimal maintenance required after insertion by a healthcare professional.

11. Question 1: What is contraception?

Answer 1: Contraception refers to the methods or devices used to prevent pregnancy by interfering with the process of fertilization or implantation.

12. Question : What are contraceptive devices?

Answer 2: Contraceptive devices are physical tools or instruments, such as condoms, intrauterine devices (IUCDs), or diaphragms, used to prevent pregnancy by blocking the sperm from reaching the egg or preventing implantation of a fertilized egg.

13. Question : What is pregnancy control?

Answer : Pregnancy control refers to the methods and techniques used to prevent pregnancy, including mechanical, chemical, hormonal, and surgical methods.

14. Question : What is the chemical method of pregnancy control?

16. Question : What is a vaginal pill in pregnancy control?

Answer : A vaginal pill, or suppository, is inserted into the vagina and releases chemicals that prevent pregnancy by killing sperm or altering the cervical mucus to prevent sperm from reaching the egg.

20. Question: What is vasectomy?

Answer: Vasectomy is a surgical procedure in men where the vas deferens (the tubes that carry sperm) are cut or sealed to prevent sperm from being released during ejaculation.

21. Question: Is the surgical method of pregnancy control reversible?

Answer: No, surgical methods like tubectomy and vasectomy are generally considered permanent and not easily reversible.

22. Question: What are the advantages of surgical methods of pregnancy control?

Answer: They are highly effective, permanent, and do not require ongoing maintenance like other contraceptive methods.

23. Question: What are the disadvantages of surgical methods of pregnancy control?
