| Situation | Requirement of contraceptive for - | Name of contraceptive device | Mode of action |
| 1 | blocking the entry of sperms through cervix | Diaphragms/cervical caps/vaults | Cover the cervix during coitus. |
| 2 | spacing between children | Cu or hormone releasing IUDs such as Cu T/Cu7/Multiload 375/Progestasert/LNG 20 | Cu ions from Cu containing IUDs increase phagocytosis of sperms within uterus, suppress sperm motility and fertilizing capacity/hormone releasing IUDs make uterus unsuitable for implantation. |
