Must-know facts

20 facts

  1. 01WHO: reproductive health is total well-being in physical, emotional, behavioural and social aspects of reproduction.
  2. 02India's family planning programmes began in 1951; today's broader ones are the RCH programmes.
  3. 03Amniocentesis tests amniotic fluid for genetic disorders; its use for sex determination is banned by law.
  4. 04Saheli: once-a-week, non-steroidal oral pill for females, developed at CDRI Lucknow.
  5. 05India: about 350 million at Independence, over 1.2 billion by May 2011; 2011 growth rate below 2% (20/1000/year).
  6. 06Legal marriageable age: 18 years for females, 21 years for males.
  7. 07Periodic abstinence avoids days 10-17 of the cycle, the fertile period.
  8. 08Lactational amenorrhea works only while the mother breast-feeds fully, up to at most six months after parturition.
  9. 09Condoms (e.g. Nirodh) also protect against STIs and AIDS; diaphragms, cervical caps and vaults cover the cervix and are reusable.
  10. 10IUDs: non-medicated (Lippes loop), copper (CuT, Cu7, Multiload 375), hormonal (Progestasert, LNG-20).
  11. 11IUDs raise phagocytosis of sperms; Cu ions cut sperm motility and fertilising capacity; hormone IUDs also block implantation and make the cervix hostile.
  12. 12Pills: progestogen or progestogen-estrogen, 21 days from within the first five days of the cycle, then a 7-day gap; they inhibit ovulation and implantation and alter cervical mucus.
  13. 13Emergency contraception: hormones or an IUD within 72 hours of coitus.
  14. 14Vasectomy cuts or ties the vas deferens; tubectomy cuts or ties the fallopian tube; both block gamete transport and are poorly reversible.
  15. 15India legalised MTP in 1971; up to 12 weeks needs one registered medical practitioner, 12-24 weeks needs two.
  16. 16MTP is relatively safe only in the first trimester (up to 12 weeks).
  17. 17Hepatitis-B, genital herpes and HIV are the STIs that are not completely curable; the rest are, if caught early.
  18. 18STI incidence is very high in the 15-24 years age group; complications include PID, still births, ectopic pregnancy, infertility and reproductive tract cancer.
  19. 19Infertility: no children after 2 years of unprotected cohabitation.
  20. 20ZIFT: zygote or embryo up to 8 blastomeres into the fallopian tube; IUT: more than 8 blastomeres into the uterus; GIFT: donor ovum into the fallopian tube; ICSI: sperm injected into the ovum; IUI: semen into the uterus.

Key terms

20 terms

Reproductive health
Total well-being in all aspects of reproduction: physical, emotional, behavioural and social (WHO).
RCH programmes
Reproductive and Child Health Care programmes, the wider successors of India's family planning programmes.
Amniocentesis
Drawing some amniotic fluid to study foetal cells and dissolved substances for genetic disorders; banned for sex determination.
MMR and IMR
Maternal mortality rate and infant mortality rate; their fall helped cause the population rise.
Fertile period
Days 10 to 17 of the menstrual cycle, when ovulation is expected and fertilisation is most likely.
Coitus interruptus
Withdrawal: the penis is withdrawn just before ejaculation to avoid insemination.
Lactational amenorrhea
Absence of menstruation during intense breast-feeding after birth; a natural method effective up to six months.
Barrier method
A contraceptive that physically keeps ovum and sperms apart, such as a condom, diaphragm, cervical cap or vault.
IUD
Intra-uterine device placed in the uterus through the vagina; non-medicated, copper-releasing or hormone-releasing.
Oral pill
Small doses of progestogens or progestogen-estrogen taken daily for 21 days; inhibits ovulation and implantation.
Emergency contraception
Hormones or an IUD used within 72 hours of coitus to avoid a possible pregnancy.
Vasectomy
Male sterilisation: a small part of the vas deferens removed or tied through a small cut in the scrotum.
Tubectomy
Female sterilisation: a small part of the fallopian tube removed or tied through the abdomen or vagina.
MTP
Medical termination of pregnancy: intentional ending of a pregnancy before full term; induced abortion.
STI
Sexually transmitted infection, also called venereal disease (VD) or reproductive tract infection (RTI).
PID
Pelvic inflammatory disease, a complication of untreated STIs.
Infertility
Inability to conceive or produce children after 2 years of unprotected sexual cohabitation.
ART
Assisted reproductive technologies such as IVF-ET, ZIFT, IUT, GIFT, ICSI and AI/IUI.
ZIFT
Zygote intra fallopian transfer: a zygote or embryo of up to 8 blastomeres placed in the fallopian tube.
GIFT
Gamete intra fallopian transfer: a donor ovum placed in the fallopian tube of a female who cannot produce ova.
