Reproductive Health

Reproductive health encompasses the total well-being of the reproductive system, including physical, emotional, and social aspects. India launched its first national family planning programme in 1951, and since then awareness through education, media, and government initiatives has improved reproductive health outcomes significantly.

Contraceptive methods are classified into five categories. Natural methods include the rhythm method (avoiding intercourse during the fertile window around ovulation, days 10-17), coitus interruptus (withdrawal before ejaculation), and lactational amenorrhea (absence of menstruation during intensive breastfeeding, effective up to six months post-partum). Barrier methods physically prevent sperm from reaching the egg: male condoms (latex sheath over penis), female condoms, diaphragms, and cervical caps (cover the cervix). Condoms also provide protection against STDs, making them unique among contraceptive methods.

Intrauterine devices (IUDs) are inserted into the uterus and work through different mechanisms. Copper-releasing IUDs (Cu-T, Cu-7, Multiload 375) release copper ions (Cu₂+) that are toxic to sperm and also increase phagocytosis of sperm. Hormone-releasing IUDs like LNG-20 release levonorgestrel, making the uterus inhospitable for implantation and thickening cervical mucus. Hormonal oral contraceptives contain synthetic progestogens (or progestogen-estrogen combinations) that prevent ovulation by suppressing gonadotropin release. Saheli, developed by CDRI Lucknow, is a notable exception: it is a non-steroidal oral contraceptive containing centchroman, taken once weekly after an initial daily loading phase. Surgical methods include vasectomy (cutting and tying the vas deferens in males) and tubectomy (cutting and tying the fallopian tubes in females). Both are highly effective but essentially irreversible.

Medical Termination of Pregnancy (MTP) is legal in India up to 20 weeks of gestation (extended to 24 weeks for special categories under the 2021 amendment). MTPs are safer when performed in the first trimester and should only be conducted by qualified medical professionals.

Sexually transmitted diseases (STDs) or sexually transmitted infections (STIs) include bacterial infections such as gonorrhoea (Neisseria gonorrhoeae), syphilis (Treponema pallidum), and chlamydiasis (Chlamydia trachomatis); viral infections like genital herpes (Herpes simplex virus type 2), hepatitis B (HBV), and HIV/AIDS; and protozoan infections like trichomoniasis (Trichomonas vaginalis). Bacterial and protozoan STDs are generally curable with antibiotics, while viral STDs are manageable but not curable. Prevention strategies include use of condoms, avoiding multiple sexual partners, and regular screening.

Infertility affects couples who are unable to conceive despite regular unprotected intercourse. Assisted Reproductive Technologies (ARTs) offer solutions. In vitro fertilization (IVF) involves fertilizing the egg outside the body and transferring the embryo to the uterus (commonly called "test tube baby"). ZIFT (Zygote Intrafallopian Transfer) transfers a zygote (up to 8-cell stage) into the fallopian tube. GIFT (Gamete Intrafallopian Transfer) transfers an unfertilized ovum from a donor and sperm into the fallopian tube for in vivo fertilization. ICSI (Intracytoplasmic Sperm Injection) directly injects a single sperm into the oocyte cytoplasm and is used in cases of severe male infertility. Artificial insemination (AI/IUI) introduces processed semen directly into the uterus.

Amniocentesis is a prenatal diagnostic technique where amniotic fluid is withdrawn to analyze fetal cells for chromosomal abnormalities. While it has legitimate medical uses (detecting Down syndrome, thalassemia), its misuse for sex determination led to its ban for that purpose under the PCPNDT Act (Pre-Conception and Pre-Natal Diagnostic Techniques Act, 1994). The key testable concept is that Saheli is a non-steroidal contraceptive (centchroman, not a hormonal pill), and that ZIFT transfers a zygote to the fallopian tube while GIFT transfers gametes (unfertilized) to the fallopian tube.
