Filter by:The study aims to explore the effects of hormonal fluctuations throughout the menstrual cycle on social media use, brain architecture, neural reward processing and reward behavior, and affective status in adolescent girls. Additionally, it strives to compare the effects of exogenous and endogenous hormones on the above-mentioned aspects. For this purpose, the investigators will compare two main groups in the study: 1. Naturally cycling adolescent girls, 2. Adolescent girls using combined oral contraceptives. This study will combine self-report data via questionnaires, ecological data via Ecological Momentary Assessment (EMA), endocrine data via blood collection, and neural data via fMRI assessment to enhance the understanding of the neurobiological mechanisms underlying social media use in adolescent girls. Furthermore, it seeks to elucidate whether there are vulnerable periods throughout the menstrual cycle when adolescent girls are especially prone to dysfunctional social media use and help to design more specific interventions as well as therapy.
The aim of our study is to assess the concentrations of different oral contraceptive agents in morbid obese women before and after two types of bariatric surgeries (RYGB and sleeve gastrectomy) in order to study the role of the surgery and the role of body weight on drug concentrations, and to compare these concentrations with those of normal-weight women.
The purpose of this study is to evaluate the contraceptive efficacy and safety of an oral contraceptive containing a combination of LNG 100mcg/EE 20mcg compared to LNG 150mcg/EE 30 mcg.
This study is being conducted to evaluate the impact of DR-102, a 28-day oral contraceptive compared to a standard 28-day oral contraceptive regimen on hemostatic parameters in healthy women.
The purpose of this research study is to gain a better understanding of the changes that may occur in the breast when a woman uses an oral contraceptive (birth control pill). Some research indicates that women who use birth control pills with lower amounts of estrogen (a hormone in the birth control pill) may have lower breast cell growth than women who use birth control pills with a higher amount of estrogen; this research will examine that in detail. This research will also test whether the results found in HS-07-00269 can be confirmed.
This study is being conducted to evaluate the impact of a 28-day oral contraceptive compared to two 28-day oral contraceptive regimens containing different synthetic progestins on ovarian follicular activity and hormone levels in healthy women.
This study is being conducted to evaluate the impact of a 91-day extended cycle oral contraceptive compared to two 28-day oral contraceptive regimens on hemostatic parameters in healthy women.
This clinical research study will examine whether an oral contraceptive pill taken with a monthly hormone-free interval of 4 days reduces hormone withdrawal associated symptoms compared to an oral contraceptive pill taken with a monthly hormone-free interval of 7 days after 4 cycles of treatment.
The purpose of this research study is to gain a better understanding of the changes that may occur in the breast when a woman uses an oral contraceptive (birth control pill). Some research indicates that women who use birth control pills with lower amounts of progestin (a hormone in the birth control pill) may have lower breast cell growth than women who use birth control pills with a higher amount of progestin; this research will examine that in detail.
The aim of the present study is to investigate whether women taking a new combined oral contraceptive pill (SH T00658ID, estradiol valerate/dienogest) experience fewer hormone withdrawal-associated symptoms such as pelvic pain or headache during their monthly cycle compared to a commonly used contraceptive pill (Microgynon).
