Mifepristone is a medication that is being tested for its effectiveness, safety, and how acceptable it is for use as a once-weekly contraceptive pill. The study aims to understand how well this medication works in preventing pregnancy and to observe any side effects or other health impacts it may have on participants.

Participants in the study will take a 50 mg tablet of mifepristone once a week. The study will monitor the occurrence of pregnancies during the treatment period to evaluate the effectiveness of the medication. Additionally, the study will look at various health aspects, such as changes in liver function, mood, sexual health, weight, and any other side effects that may occur. The study will also assess how participants feel about using mifepristone as their method of contraception.

The trial will last for a period of up to 12 months, during which participants will be asked to keep a daily diary and complete online questionnaires. The study will gather information on the overall experience of using mifepristone as a contraceptive, including any decisions regarding pregnancy continuation or termination, and any related health outcomes. This research will help determine if mifepristone is a viable option for contraception in the future.

]]> Study on the Effects of Ethinylestradiol, Levonorgestrel, and Chlormadinone Acetate in Hormonal Contraception for Women Using Oral Contraceptives https://clinicaltrials.eu/trial/study-on-the-effects-of-ethinylestradiol-levonorgestrel-and-chlormadinone-acetate-in-hormonal-contraception-for-women-using-oral-contraceptives/ Wed, 29 Apr 2026 15:05:30 +0000 https://clinicaltrials.eu/trial/study-on-the-effects-of-ethinylestradiol-levonorgestrel-and-chlormadinone-acetate-in-hormonal-contraception-for-women-using-oral-contraceptives/ This clinical trial is focused on studying the effects of hormonal contraception on the brain and behavior. The study involves two types of combined oral contraceptives: Selina Gynial, which contains ethinylestradiol and levonorgestrel, and Bilinda Gynial, which contains ethinylestradiol and chlormadinone acetate. These medications are commonly used for birth control and are taken in the form of film-coated tablets.

The purpose of the study is to understand how these oral contraceptives affect brain structure, brain function, and behavior over a period of up to six months. The study will also look at how these effects might change when the medication is stopped. Researchers will examine various factors, such as age and the type of contraceptive used, to see how they might influence the body’s response to the medication.

Participants in the study will take the oral contraceptives and undergo assessments to measure changes in mood, self-perception, and cognitive abilities like memory and face recognition. The study will also monitor changes in brain structure and function. Additionally, the study will measure levels of sex hormones, stress hormones, and the contraceptive drugs in the body. Genetic factors that might affect how the body responds to these hormones will also be explored. The study aims to provide a better understanding of the broader effects of hormonal contraception on the body and mind.
