Which of following is a contraceptive?

The correct answer is All of these.

Explanation-

Contraception is used to prevent pregnancy. Different methods can suit different people based on health, lifestyle, and personal preference. Here are several types of contraceptives used by humans:-

1. Barrier Methods: These physically prevent sperm from reaching the egg.

• Condoms: There are both male and female condoms, which provide a physical barrier between the sperm and egg.
• Diaphragms and Cervical Caps: These are placed inside the vagina to cover the cervix and prevent the sperm from accessing the uterus.

2. Hormonal Methods: These use hormones to regulate or stop ovulation and prevent pregnancy.

• Birth Control Pills: They contain hormones that prevent ovulation and thicken cervical mucus which makes it harder for sperm to enter the uterus.
• The Patch: A skin patch worn on the lower abdomen, buttocks, or upper body releases hormones through the skin into the bloodstream to prevent ovulation.
• Vaginal Ring: Inserted into the vagina, where it releases hormones to suppress ovulation.

3. Intrauterine Devices (IUDs): Small devices placed in the uterus that can prevent pregnancy either through a physical barrier or by releasing hormones.

• Copper IUD : This device doesn't release hormones. Instead, the copper triggers your immune system to prevent pregnancy.
• Hormonal IUD: These devices release progestin, a hormone that helps to prevent ovulation and thickens cervical mucus, making it more difficult for sperm to reach an egg.

4.Emergency Contraception: These are methods used to prevent pregnancy after unprotected sex.

• The Morning-After Pill : This pill works by delaying or preventing ovulation, thus preventing the potential fertilization of an egg.
• Copper IUD: This can also be used as a form of emergency contraception if inserted within five days after unprotected sex.

5.Permanent Contraception (Sterilization): These are surgical procedures intended to provide permanent contraception.

• Tubal Ligation: This is a surgical procedure where a woman's Fallopian tubes are blocked, tied, or cut.
• Vasectomy: A surgical procedure for males where the vasa deferentia (sperm-carrying tubes) are cut, tied, or otherwise sealed.
