Information Booster:

• Condom: A mechanical barrier method that prevents sperm from entering the uterus. It can be worn by either the male or the female during sexual intercourse and is effective in preventing pregnancy and sexually transmitted infections (STIs).
• Pill: A chemical method of contraception, commonly known as the oral contraceptive pill. It contains hormones (typically estrogen and progesterone) that prevent ovulation (the release of eggs from the ovaries), making it difficult for sperm to fertilize an egg. It is taken daily.
• Copper T (Intrauterine Device - IUD): This is a device placed in the uterus. The Copper T is a type of IUD that releases copper, which is toxic to sperm, making it an effective barrier to fertilization. It can be a long-term form of contraception.
• Vasectomy: This is a surgical method of contraception for men. It involves cutting or blocking the vas deferens (the tubes that carry sperm), preventing sperm from mixing with semen during ejaculation. It is considered a permanent method of contraception.
