Explore contraceptive methods by category: natural, barrier, IUD, hormonal pills, injectables and surgical.
Select a category to see examples, how the method works, its advantages, its limitations and the NEET fact tested about it.
IUDs
Examples
How it works
Inserted into the uterus by a doctor. Non-medicated IUDs cause a local inflammatory reaction hostile to implantation. Copper IUDs release Cu2+ ions that suppress sperm motility. Hormone IUDs (LNG-20) thicken cervical mucus, thin the endometrium and can suppress ovulation.
Advantages
Long-acting (3 to 10 years), reversible, highly effective, no daily action required.
Limitations
Requires insertion and removal by a trained healthcare provider. May cause heavier periods (copper IUDs). Not suitable for women with certain uterine conditions.
NEET fact
Know the three IUD types: non-medicated (Lippes loop), copper (CuT, Multiload 375), hormone-releasing (LNG-20). Cu2+ suppresses sperm motility.

Select any ART technique to see its full name, step-by-step procedure, where transfer happens, and who the technique helps most.
Feature
IVF
ZIFT
GIFT
ICSI
IUI / AI
Transfer site
Embryo transferred into the uterus
Zygote transferred into the fallopian tube
Unfertilised gametes (egg + sperm) transferred into the fallopian tube
Embryo transferred into the uterus (same as IVF)
Processed sperm placed into the uterus
Fertilisation
Fertilisation happens in the lab (in vitro)
Fertilisation happens in the lab (in vitro), then zygote placed in tube
Fertilisation happens inside the fallopian tube (in vivo)
Fertilisation by direct sperm injection into egg cytoplasm (in vitro)
Fertilisation happens naturally inside the fallopian tube (in vivo)
IVF: In Vitro Fertilisation
Procedure
Eggs are collected from the woman after hormonal stimulation (superovulation). Sperm is collected from the male partner. Eggs and sperm are mixed in a laboratory dish (in vitro) and fertilisation occurs outside the body. The resulting embryo is grown in the lab for 2 to 5 days and then placed into the uterus via a thin catheter (IET: Intra Uterine Embryo Transfer).
Used for
Blocked or damaged fallopian tubes, unexplained infertility, failed natural conception after 1 year, some male factor infertility.
NEET fact
IVF = "test tube baby". First IVF baby: Louise Brown (1978). First IVF baby in India: Durga/Kanupriya Agarwal (1978).

Explore sexually transmitted infections with the causative pathogen, symptoms, whether they are curable and prevention.
Select any STI to see its causative pathogen, key symptoms, whether it is curable, and how to prevent it. Colour-coded by pathogen type: red for bacteria, purple for viruses, blue for protozoa.
Gonorrhoea
Syphilis
Genital Herpes
Chlamydiasis
Hepatitis B
HIV / AIDS
Genital Warts
Trichomoniasis
Gonorrhoea
Pathogen
Neisseria gonorrhoeae(Bacterium)
Symptoms
Thick yellowish-white discharge from the penis or vagina. Burning sensation during urination. In females, often asymptomatic at first, leading to delayed diagnosis. Can progress to pelvic inflammatory disease (PID) if untreated.
Curability
Curable with antibiotics (penicillin or cephalosporins), though antibiotic-resistant strains are emerging.
Prevention
Consistent condom use. Regular STI testing for sexually active individuals. Treatment of infected partners.
NEET fact
Caused by Neisseria gonorrhoeae (bacterium). Curable. One of the most common bacterial STIs.
