REP-03 — 5 Essential Bullets
-
Saheli = NON-STEROIDAL: Centchroman, CDRI Lucknow, once weekly, blocks estrogen receptors → prevents implantation (NOT ovulation). Not a hormonal steroid pill.
-
ART transfer sites: ZIFT (zygote) and GIFT (gametes) → fallopian tube; IVF-ET (embryo) → uterus; ICSI (one sperm into oocyte cytoplasm) → uterus; GIFT = only ART with in vivo fertilization.
-
STDs — NTC curable, HHH not curable: Neisseria/Treponema/Chlamydia (bacteria) = curable; Herpes/HBV/HIV (viruses) = not curable; Trichomonas (protozoan) = curable; Hepatitis B has vaccine.
-
Key laws: India FP programme (1951); MTP Act (1971, 20 weeks standard; 2021 amendment 24 weeks special categories); PCPNDT Act (1994, bans sex determination by prenatal tests).
-
Only condoms protect against STDs: No other contraceptive — not IUDs, pills, Saheli, or surgical methods — provides STD protection; Cu-T non-hormonal (Cu2+ spermicidal + phagocytosis); LAM effective only 6 months exclusive breastfeeding.
