Presently preferred is the use of the synthetic estrogen, ethinyl estradiol, and the synthetic progestin, levonorgestrel. Along with these two steroidal contraceptive agents, a combination of several chemical skin permeation enhancing agents, including capric acid, blended at specific weight ratios, ranging from 2:1:1:0.8 to 6:1:1:0.8, are homogeneously dispersed in the adhesive polymer matrix. The invention also provides a method of fertility control utilizing the transdermal contraceptive delivery system.
