Reproductive Health

The One Thing

Reproductive health is a state of complete physical, mental, emotional and social well-being in matters related to the reproductive system. It depends on informed contraceptive choices, responsible sexual behaviour, appropriate management of infertility, and the prevention, diagnosis and treatment of sexually transmitted diseases.

Reactions, Processes and Experiments

Key Terms

• Reproductive health: A state of healthy reproductive organs, normal reproductive functions and responsible, safe reproductive behaviour.
• Family planning: The planned regulation of the number and spacing of children using suitable contraceptive methods.
• Contraception: The deliberate prevention of pregnancy by preventing ovulation, fertilisation, implantation or the release of sperm.
• Natural methods: Methods such as periodic abstinence, withdrawal and lactational amenorrhea that avoid artificial devices or hormones.
• Periodic abstinence: Avoiding sexual intercourse during the fertile period, commonly around days 10 to 17 of a typical 28-day menstrual cycle.
• Lactational amenorrhea: Temporary prevention of ovulation during intense breastfeeding, generally effective for up to six months after childbirth if menstruation has not resumed.
• Barrier methods: Methods such as condoms, diaphragms, cervical caps and vaults that physically prevent sperm from reaching the ovum.
• Condom: A thin sheath worn over the penis or placed inside the vagina that prevents sperm entry and provides significant protection against many STDs.
• Intrauterine device (IUD): A device placed inside the uterus to prevent pregnancy; examples include non-medicated, copper-releasing and hormone-releasing IUDs.
• Copper-releasing IUD: An IUD that releases copper ions, reducing sperm motility and fertilising ability and increasing phagocytosis of sperm.
• Hormone-releasing IUD: An IUD that releases hormones and helps prevent fertilisation and implantation while making cervical mucus less suitable for sperm movement.
• Oral contraceptive pills: Hormonal pills, usually containing progesterone or a combination of oestrogen and progesterone, that inhibit ovulation and alter cervical mucus and the uterine lining.
• Emergency contraceptive: A method used soon after unprotected intercourse to reduce the chance of pregnancy; it is not intended for regular use.
• Injectable and implant contraceptives: Long-acting hormonal methods that suppress ovulation and change cervical mucus, providing contraception for an extended period.
• Surgical methods: Permanent methods involving blockage of gamete transport: vasectomy blocks the vas deferens in males, while tubectomy blocks the fallopian tubes in females.
• Medical termination of pregnancy (MTP): The intentional termination of pregnancy using approved medical methods under legal and medical supervision.
• Infertility: The inability to conceive or produce children despite regular unprotected sexual intercourse, often due to physiological, genetic, disease-related or psychological causes.
• Assisted reproductive technology (ART): Medical techniques used to help achieve pregnancy when natural conception is difficult.
• In vitro fertilisation (IVF): Fertilisation of an ovum by sperm outside the body, followed by transfer of the resulting embryo into the female reproductive tract.
• Zygote intrafallopian transfer (ZIFT): Transfer of a zygote or early embryo into the fallopian tube after fertilisation outside the body.
• Gamete intrafallopian transfer (GIFT): Transfer of an ovum or ova and sperm into the fallopian tube so that fertilisation may occur inside the body.
• Intrauterine insemination (IUI): Placement of specially prepared semen directly into the uterus to increase the chance of fertilisation.
• Sexually transmitted disease (STD): An infection mainly transmitted through sexual contact, including infections caused by bacteria, viruses, fungi or protozoans.
• Examples of STDs: Gonorrhoea, syphilis, chlamydiasis, genital herpes, genital warts, trichomoniasis, hepatitis-B and HIV infection.
• HIV/AIDS: HIV attacks immune cells and may lead to AIDS, a condition in which the immune system becomes severely weakened.
• STD prevention: Prevention includes mutual monogamy with an uninfected partner, correct condom use, avoiding multiple or unknown sexual partners, sterile needles, screened blood and timely medical testing.

Easily Confused

• Periodic abstinence vs lactational amenorrhea: Periodic abstinence avoids intercourse during the fertile period, whereas lactational amenorrhea relies on temporary suppression of ovulation during intense breastfeeding.
• Condoms vs other barrier methods: Condoms physically block sperm and also provide significant protection against many STDs; diaphragms, cervical caps and vaults are barrier methods but are not described here as providing the same level of STD protection.
• Copper-releasing IUD vs hormone-releasing IUD: Copper IUDs impair sperm motility and fertilising ability and increase phagocytosis, whereas hormone-releasing IUDs alter cervical mucus and help prevent fertilisation and implantation.
• Emergency contraception vs regular contraception: Emergency contraception is used soon after unprotected intercourse and is not intended for regular use.
• Vasectomy vs tubectomy: Vasectomy blocks the vas deferens in males, whereas tubectomy blocks the fallopian tubes in females; neither normally stops sex-hormone production.
• IVF vs GIFT: IVF involves fertilisation outside the body, whereas GIFT transfers ova and sperm into the fallopian tube so fertilisation may occur inside the body.
• IVF vs ZIFT: IVF is the external fertilisation procedure; ZIFT specifically transfers the resulting zygote or early embryo into the fallopian tube.
• Infertility vs contraception: Infertility is difficulty conceiving despite regular unprotected intercourse, whereas contraception deliberately prevents pregnancy.
• HIV transmission vs casual contact: HIV may be transmitted through unprotected sexual contact, infected blood, contaminated needles or mother-to-child transmission, but not through shaking hands or sharing food.

What Gets Asked

• Define reproductive health, family planning and contraception, including the reproductive processes that contraception may prevent: ovulation, sperm transport, fertilisation, implantation or gamete formation.
• Compare contraceptive methods by effectiveness, safety, convenience, reversibility, cost and protection against STDs; the key mark-losing error is treating every method as equally protective against STDs.
• Explain the mechanisms of copper-releasing IUDs, hormone-releasing IUDs and oral contraceptive pills; do not interchange copper-ion effects with hormonal effects.
• Distinguish vasectomy from tubectomy and state that these procedures block gamete transport but normally do not stop sex-hormone production.
• Describe infertility and the principal assisted reproductive technologies—IVF, ZIFT, GIFT and IUI—especially the difference between fertilisation outside the body and gamete transfer for fertilisation inside the body.
• Identify STD symptoms, complications and routes of HIV transmission, and state preventive measures including correct condom use, sterile needles, screened blood, hepatitis-B vaccination, testing and avoidance of contaminated needles; casual contact such as shaking hands or sharing food does not transmit HIV.
