Reproductive Health
10 lessons 81 min 2 simulations
This chapter widens reproduction from organs to society. It defines reproductive health, follows India's programmes from family planning to RCH, explains why the population grew so fast, and then walks through every contraceptive group from periodic abstinence to sterilisation. It closes with three problems that need care and law: medical termination of pregnancy, sexually transmitted infections and infertility, with the assisted reproductive technologies that help infertile couples.
What the exam asks
NEET asks for the mode of action of each contraceptive (what IUDs, copper ions, hormone IUDs and pills do), example names (Lippes loop, CuT, Multiload 375, Progestasert, LNG-20, Saheli, Nirodh), the numbers (days 10-17, 21 + 7 days, first five days, six months, 72 hours, 12 and 24 weeks, 15-24 years, 2 years, 8 blastomeres), which STIs are not curable, and the match of ZIFT, IUT, GIFT, ICSI and IUI to what is transferred and where. Marks are lost by saying sterilisation stops gamete formation, by sending every embryo to the uterus, and by reading GIFT as transfer of a zygote.
