Understanding Family Planning Methods
Family planning refers to the decision-making process by individuals and couples concerning the number of children they wish to have, and when they wish to have them. It involves the use of various methods to control conception, thereby ensuring reproductive health and well-being.
Key Objectives of Family Planning:
- Preventing unintended pregnancies.
- Spacing births to allow adequate recovery time for the mother and proper care for existing children.
- Limiting family size for improved quality of life.
- Protecting against sexually transmitted infections (STIs) in some cases.
Classification of Contraceptive Methods:
1. Barrier Methods
Barrier methods prevent the union of sperm and ovum by physically blocking their path. They are generally safe and some also offer protection against STIs.
- Condoms: Thin rubber/latex sheath used by males (or females) to cover the penis (or line the vagina) during coitus. It prevents semen from entering the female reproductive tract and also protects against STIs.
- Diaphragms, Cervical Caps, and Vaults: These are barriers made of rubber that are inserted into the female reproductive tract to cover the cervix before coitus. They block sperm entry and are often used with spermicidal creams/jellies to increase their effectiveness.
2. Hormonal Methods
These methods use hormones (estrogen and/or progestogen) to alter the female reproductive cycle, primarily by inhibiting ovulation, altering cervical mucus to impede sperm entry, or making the uterus unsuitable for implantation.
- Oral Contraceptive Pills: These are small doses of hormones (progestogens or progestogen-estrogen combinations) taken daily. They inhibit ovulation and alter the quality of cervical mucus to prevent sperm entry.
- Injections and Implants: Progestogen-only injections (e.g., Depo-Provera) or implants (e.g., Norplant) are long-acting hormonal methods that release hormones slowly into the body, providing protection for several months to years.
- Vaginal Rings and Patches: These release hormones that are absorbed through the vaginal lining or skin, similar to oral pills but with different administration routes.
3. Intrauterine Devices (IUDs)
IUDs are small devices inserted by a doctor into the uterus. They are highly effective spacing methods.
- Non-medicated IUDs: E.g., Lippes Loop. They increase phagocytosis of sperm within the uterus.
- Copper-releasing IUDs: E.g., CuT, Cu7, Multiload 375. They release copper ions which suppress sperm motility and fertilizing capacity. They also make the uterus unsuitable for implantation.
- Hormone-releasing IUDs: E.g., Progestasert, LNG-20. They make the uterus unsuitable for implantation and the cervix hostile to sperm.
4. Surgical Methods (Sterilization)
These are permanent methods of contraception, highly effective and irreversible.
- Vasectomy (Males): A small incision is made in the scrotum, and the vas deferens are cut and tied off. This prevents sperm from reaching the semen.
- Tubectomy (Females): A small incision is made in the abdomen or through the vagina, and the fallopian tubes are cut and tied off. This prevents the ovum from reaching the uterus and sperm from reaching the ovum.
5. Spacing Methods (Natural Methods)
These methods rely on understanding the female reproductive cycle to avoid conception and do not involve any drugs or devices.
- Rhythm Method (Calendar Method): Avoiding coitus during the fertile period (around days 10-17 of the menstrual cycle) when ovulation is expected.
- Coitus Interruptus (Withdrawal Method): Withdrawal of the penis from the vagina just before ejaculation.
- Lactational Amenorrhea: Based on the principle that ovulation does not occur during intense lactation (breastfeeding) following parturition (childbirth), for a period up to six months.
Summary Table of Family Planning Methods
| Method Type | Examples | Key Mechanism | Effectiveness |
|---|---|---|---|
| Barrier | Condom, Diaphragm | Physical block for sperm | Moderate to High |
| Hormonal | Oral Pills, Injections, Implants | Inhibit ovulation, alter cervical mucus | High |
| IUDs | CuT, LNG-20 | Prevent implantation, affect sperm | Very High |
| Surgical | Vasectomy, Tubectomy | Permanent blockage of gamete transport | Almost 100% |
| Natural/Spacing | Rhythm Method, Lactational Amenorrhea | Avoid fertile period/ovulation | Variable, generally Lower |
Quick Revision Points:
- Family planning methods help manage birth spacing and family size.
- Barrier methods (condoms, diaphragms) physically prevent sperm-ovum union and can prevent STIs.
- Hormonal methods (pills, injections, implants) primarily inhibit ovulation.
- IUDs (Copper-T, hormonal IUDs) are inserted into the uterus and prevent implantation or affect sperm.
- Surgical methods (vasectomy, tubectomy) are permanent sterilization techniques.
- Natural methods (rhythm, coitus interruptus, lactational amenorrhea) rely on timing and natural body processes.
Practice Questions:
- Explain the principle behind the working of oral contraceptive pills.
- Differentiate between vasectomy and tubectomy with respect to the reproductive structures involved.
- List two advantages of using barrier methods of contraception.
- How do copper-releasing IUDs prevent pregnancy?
- Describe the lactational amenorrhea method and its limitations.
