A contraceptive technique that increases phagocytosis of sperms within the uterus is:

Correct option is D

The correct answer is (d) use of copper T.

·         The Copper T is an intrauterine device (IUD) that prevents pregnancy through multiple mechanisms, one of which is increasing the phagocytosis of sperms within the uterus.

·         The copper ions released by the Copper T create a hostile environment for sperm, inhibiting their motility and survival.

·         Additionally, the presence of the device triggers an immune response in the uterus, leading to the phagocytosis (destruction) of sperms by white blood cells.

Information Booster:

·         Copper T is a highly effective and long-lasting contraceptive method, often used for years without replacement.

·         It works by releasing copper ions, which are toxic to sperm, reducing their motility and viability.

·         The immune response stimulated by the device further prevents fertilization by promoting sperm destruction.

Additional Knowledge:

·         Use of oral contraceptives: Prevents ovulation by regulating hormones but does not involve phagocytosis.

·         Use of condoms: Provides a physical barrier to prevent sperm from entering the uterus but does not increase phagocytosis.

·         Surgery: Refers to sterilization methods like tubectomy or vasectomy, which block gamete transport but do not involve phagocytosis.
