Summary
This trial aims to understand how differences in our DNA can affect how our bodies process hormones in birth control pills, potentially influencing their effectiveness in preventing pregnancy and causing different side effects in individuals. Participants will take
Who is the study for?
This trial is for individuals using a specific birth control pill (desogestrel/ethinyl estradiol). It's focused on how genetic differences affect the body's processing of these hormones and their effectiveness in preventing pregnancy. Participants will have blood tests, answer questionnaires about side effects, and may opt for an ultrasound to check ovarian follicles.
What is being tested?
The study is testing how the CYP3A7*1C gene variant affects metabolism of hormones in oral contraceptives and if it leads to more cases of breakthrough ovulation. It also seeks new genetic factors that influence hormone levels among users of these pills.
What are the potential side effects?
Possible side effects from taking the combined oral contraceptive pill include nausea, headaches, mood changes, weight gain, menstrual irregularities, and other hormonal-related issues.
