The conventional regimen for hormonal oral contraceptives is a 21-day pill-taking period followed by a 7-day pill-free interval. In a recent survey among 252 oral contraceptive users in five European countries, women were asked if they were aware of the possibility of postponing menstruation by delaying pill intake and whether they had used this method. Overall, 32% had delayed menstruation at some time, and 37% were aware of the method but had not used it. Of the 79 women who had postponed menstruation, almost two-thirds had seldom done so, while 11% used the method more than once every 3 months. The majority of these women had delayed their menstruation for a period ranging from 1 week to 3 months. In the total population surveyed, 46% were very or somewhat interested in trying the concept of postponement. 

In a large, prospective, observational 6-month study in Germany, cycle control, premenstrual symptoms and general well-being were compared in 1433 women taking the oral contraceptive Yasmin®, containing 30 µg ethinylestradiol and 3 mg drospirenone, in either an extended regimen (63–126 days) or a conventional regimen (short cycle). Fluid retention was reduced in 49% of women on the extended regimen compared to 34% of women on the conventional regimen. Women reported a reduction in breast tenderness of 50% on the extended regimen and 40% on the short-cycle regimen, while one-third of the women on either regimen noticed an improvement in their skin condition. Improvement in dysmenorrhea was reported by 65% and 50% of women on the extended and short regimens, respectively. General well-being was improved in 85% on the extended regimen and 66% on the short-cycle regimen (p<0.0001). Altogether, 97% of extended-cycle users and 91% of short-cycle users would recommend Yasmin® for further treatment. These results confirm previous observations that Yasmin® reduces premenstrual symptoms and improves general well-being. These effects were further increased through application of an extended cycle regimen.
