Hormonal Contraceptives

  • Birth Control Pills: Oral contraceptives contain hormones that prevent ovulation, making it challenging for sperm to fertilize an egg.
  • Contraceptive Patch: A patch releases hormones through the skin, similarly inhibiting ovulation and altering cervical mucus to impede sperm movement.
  • Contraceptive Injection: Hormonal injections provide protection against pregnancy for a few months by preventing ovulation and affecting the uterine lining.

Barrier Methods

  • Condoms: Male and female condoms provide a physical barrier that prevents sperm from reaching the egg.
  • Diaphragms and Cervical Caps: These devices cover the cervix to prevent sperm from entering the uterus.

Intrauterine Devices (IUDs)

  • Hormonal IUD: This small device is placed in the uterus and releases hormones that affect ovulation and create an inhospitable environment for sperm.
  • Copper IUD: The copper IUD interferes with sperm motility and prevents fertilization by altering the uterine environment.

Natural Methods

  • Fertility Awareness: Tracking menstrual cycles and ovulation to avoid intercourse during fertile periods.
  • Withdrawal Method: The man withdraws his penis before ejaculation, reducing the chance of sperm reaching the egg.

Permanent Solutions

  • Tubal Ligation: Also known as “getting your tubes tied,” this surgical procedure prevents eggs from reaching the uterus.
  • Vasectomy: A surgical procedure that blocks the tubes carrying sperm, making a man sterile.

Emergency Contraception

Emergency contraceptive pills, also known as “morning-after pills,” can be taken after unprotected intercourse to prevent pregnancy.


In the realm of reproductive health, boric acid’s potential as a spermicide sparks interest, yet its safe and effective application requires careful consideration.
