Introduction: Family planning programs in Islamic Republic of Iran are faced
with limited resources. So evaluation of family planning programs, in order to
determine how much we have reached our targets, is extremely important. The
easiest way to evaluate the results of these activities is using the couple-year of
protection method.
Methods: This descriptive study was conducted to determine the couple- year of
protection (CYP) of two methods of contraception of condom and vasectomy.
Two hundred condom users and 200 women whose husbands have undergone
vasectomy were selected by simple random sampling from the therapeutic and
health centers in Jahrom. The condom users and those resorting to vasectomy
were asked about the mean coital frequency per month and the age of using
permanent contraceptive method respectively, and then CYP was calculated.
Results: CYP was 0.011 for condom, 14 for vasectomy in this study. Mean live
children number was 2.68±1.32 for vasectomy. CYP of vasectomy was more
than Wishek coefficient.
Conclusion: Regarding the importance of age of using these methods in
providing protection, this method must be done in younger age. Also, CYP of
condom was more than Wishek coefficient (0.01).
