Three techniques that have been developed to prevent pregnancy are:
- Barrier method: This method prevents the sperm from meeting the egg by using barriers such as condoms, diaphragms, and cervical caps.
- Oral contraceptives: These are pills that contain hormones that prevent ovulation.
- Intrauterine devices (IUDs): These are devices that are inserted into the uterus to prevent implantation of the fertilized egg.
The technique that is not meant for males is oral contraceptives.
The use of these techniques has a direct impact on the health and prosperity of a family by allowing them to plan their family size and spacing, which can lead to improved health and economic outcomes.
