what are the mechanical methods of controlling population?
Mechanical methods of birth control are:
i) Male Condom
ii) Female Condom
Both of these prevent the sperm from meeting the egg.
iii) Intrauterine Device (IUD) – a T-shaped device placed inside the uterus (by a doctor) which blocks the sperms from entry into the fallopian tubes
iv) Intrauterine System (IUS) – a device similarly designed and administered as the IUD which releases hormones that thicken the cervical mucus thus blocking sperms from entry into the uterus
v) Diaphragm, Cervical Cap, and Shield – latex or silicon cap used with spermicides which blocks the entry of sperms into the cervix
vi) Sponge – a soft, disk-shaped device that a woman wets and inserts into the vagina, and thus covering the cervix and blocking the sperms
