ABBR: CYP. In family planning, the number of days per year that any method of birth control will prevent conception. Abstinence from sexual intercourse, or sterilization of both members of a couple, provides absolute (365 days/year) protection. Other methods of family planning or fertility inhibition are relatively less effective. Couples that attempt penile withdrawal before male climax (coitus interruptus) have the lowest levels of CYP of any method. Condoms provide a moderate increase in contraceptive effectiveness but are less effective than intrauterine devices, contraceptive pills, or contraceptive implants.
