Ideal Contraceptive Properties & Methods — NEET Biology
📚 Practice ConceptAn ideal contraceptive should be user-friendly, easily available, effective and reversible with no or least side-effects. It also should in no way interfere with the sexual drive, desire and/or the sexual act of the user. A wide range of contraceptive methods are presently available which could be broadly grouped into the following categories, namely Natural/Traditional, Barrier, IUDs, Oral contraceptives, Injectables, Implants and Surgical methods.
Which of the following statements regarding contraceptive methods are NOT correct? S1: Condoms, diaphragms, cervical caps, and vaults are barrier methods that prevent conception by physically blocking sperm entry into the female reproductive tract. S2: Intra Uterine Devices (IUDs) are generally self-inserted by the user and are primarily effective only for delaying pregnancy, not for spacing children. S3: Copper-releasing IUDs like CuT and Cu7 increase phagocytosis of sperms within the uterus and suppress sperm motility. S4: Oral contraceptive pills primarily work by blocking gamete transport, similar to surgical methods, making them highly irreversible. S5: Vasectomy involves tying up a small part of the vas deferens in males, while tubectomy involves removing or tying up a small part of the fallopian tube in females. S6: Saheli, a new oral contraceptive for females, is a daily non-steroidal pill with very few side effects and high contraceptive value.
