Filter by:The project is a two-arm prospective cohort and pharmacokinetic study comparing levonorgestrel and ethinyl estradiol pharmacokinetics in HIV-positive women taking antiretroviral regimens that include ritonavir to those in women who take regimens known not to interact with combined oral contraceptives. In addition, the prevalence of ovulation will be measured in each group. Participants will take a combined oral contraceptive containing levonorgestrel and ethinyl estradiol for 21 days, during which they will undergo twice-weekly serum progesterones. On the final day, they will complete a pharmacokinetic study. The investigators hypothesize that levonorgestrel levels, as measured by area-under-the-curve from 0 to 72 hours, will be increased in women on ritonavir, while ethinyl estradiol levels will be decreased and ovulation, defined by a serum progesterone of at least 3 ng/mL, will be unchanged. This study will be the first to evaluate the effects of ritonavir on the pharmacokinetics of a combined oral contraceptive containing the progestin levonorgestrel. In addition, no previous studies have rigorously assessed ovulation in women taking protease inhibitors and combined oral contraceptives. As a result, this study will provide new information correlating pharmacokinetic changes with effects on ovulation.
The research questions are: 1. What is the proportion of women undergoing hysterectomy after hysteroscopic sterilization or laparoscopic tubal ligation? 2. What is the proportion of women undergoing salpingectomy, salpingostomy, or hysteroscopy after hysteroscopic sterilization or laparoscopic tubal ligation? 3. What is the proportion of women who have a diagnosis of pelvic pain after hysteroscopic sterilization or laparoscopic tubal ligation?
The purpose of this study is to assess the contraceptive efficacy of the Etonogestrel (ENG) + 17β-Estradiol (E2) vaginal ring in women between 18 and 35 years of age based on the number of in-treatment pregnancies as expressed by the Pearl Index (PI). The study will also assess the safety and tolerability of the ENG-E2 vaginal ring.
This was a prospective, open-label, single-drug, uncontrolled, observational clinical study. Women attending the Family Planning Association of Hong Kong (FPAHK) for emergency contraception within 120 hours of UPSI were recruited. Subjects were recruited from both the Birth Control Clinics and Youth Health Care Centres of the FPAHK. Depending on the timing in relation to ovulation in the current menstrual cycle at the time of presentation, the women were classified into two groups: Group 1: pre-ovulatory Group 2: post-ovulatory After counseling and obtaining informed consent, eligible subjects received a single dose of ulipristal acetate 30 mg (ellaOne®) under direct supervision. A baseline blood test for hormonal profile (LH, oestradiol and progesterone) and ultrasound scan for ovarian follicle assessment were carried out by a designated doctor or research nurse at the clinic visit. The subjects were advised not to have further acts of coitus before the return of menstruation. They were given a diary chart to record vaginal spotting and bleeding, possible side effects and further acts of intercourse, if any, and the contraceptive method used. A follow-up appointment were be arranged about 1-2 weeks after the expected next menstruation. Any events of unplanned pregnancy and adverse effects were recorded for analysis.
Using a very broad survey, the objective is to confirm the effectiveness of the Essure method, and to obtain more information on the conditions of use as well as on the methods used during the 3-month check-up, as well as the 12-month, 24-month and 5-year follow-up on patients.
This randomized clinical trial will study subcutaneous depot medroxyprogesterone acetate (DMPA sc) self-administration at two Planned Parenthood affiliates serving diverse patient populations. Prior studies demonstrate that DMPA self-injection is safe, effective, feasible, and acceptable for women and adolescents. A total of 400 female patients (ages 15-44) requesting DMPA will be randomized to self-administration of DMPA sc or clinic administration (usual care). Subjects will be followed for one year. The primary study outcome is DMPA continuation at one year by self-report in both study arms. Secondary outcomes include patient-reported satisfaction with treatment; satisfaction with home use; and costs associated with contraceptive care. The investigators hypothesize higher continuation rates among self-injection users compared to patients who receive standard care. Secondary exploratory hypotheses include higher patient satisfaction and lower costs associated with contraceptive care among self-injection users.
Investigation of pharmacological effects, drug blood levels and safety of an intrauterine system releasing the study drug BAY1007626 in comparison to Mirena and Jaydess in healthy young women treated for 90 days to determine the drug dose for further development
The purpose of this pilot study is to determine the feasibility of comprehensive contraceptive counseling intervention in a pediatric emergency department and to determine the impact of comprehensive contraception counseling on initiation of contraception among sexually active adolescents presenting to a pediatric emergency department.
This study aims to assess whether there is change in the growth and development of newborns whose mothers will have a etonogestrel (ENG) releasing implant inserted in the first 24 to 48 hours of delivery compared with those with standard implant insertion (6 week postpartum).
The purpose of this study is to evaluate the safety of ContraGel versus the hydroxyethylcellulose (HEC) Universal Placebo gel when used with the Caya diaphragm during two 7-day periods of daily use, the first without intercourse and the second with intercourse.
