Researchers want to learn more about user satisfaction in women in Russia who take estradiol valerate/ dienogest as a contraceptive in real conditions.

Estradiol valerate/ dienogest is a form of birth control. This is also known as a combined oral contraceptive (COC). Earlier studies showed that estradiol valerate/ dienogest has high level of protection from unplanned pregnancy. It is available for doctors to prescribe to women who want to take an oral contraceptive.

Estradiol valerate/ dienogest as a combined oral contraceptive (COC), works by stopping a process called ovulation. This is the process by which the ovaries release an egg. COCs are commonly used by young women to prevent pregnancy.

The researchers in this study will collect information from young women (18-35 years of age) in Russia who will start taking estradiol valerate/ dienogest.

The main purpose of this study is to find out about the women's satisfaction with taking estradiol valerate/ dienogest. To do this, the researchers will ask "how satisfied are you with the birth control method used during the study?". They will ask this question after the women have taken estradiol valerate/ dienogest for 3 and 6 months. The women willanswer this question using a rating scale ranging from 1 to 5, with 1 meaning "very dissatisfied" and 5 meaning "very satisfied".

This study will include young women (18-35 years of age) who want to use oral contraceptives and have been prescribed estradiol valerate/ dienogest by their doctor. None of the women in the study will have taken estradiol valerate/ dienogest within 1 month of joining the study.

In this study, it is expected that each woman will visit her study site 3 times. Each woman will be in the study for up to 6 months. All of the women will take estradiol valerate/ dienogest as prescribed by their doctors.

During the study, the women will answer a question about how satisfied they are with estradiol valerate/ dienogest. They will also respond to some questionnaires. These will include a questionnaire about their menstrual bleeding patterns, sexual function. The doctors will:

• ask the women about any medical conditions they may have and what other contraceptives they took before they joined the study
