Filter by:The use of progestin-only methods of contraception has been increased obviously and progressively over the world in the last few years. Progestin-only contraception is an option for women in whom an estrogen-containing contraceptive is either contraindicated or causes additional health concerns. Progestogen-only pills are contraceptive pills that contain only synthetic progestogens (progestins) and do not contain estrogen . The progestin-only pill is recommended over regular birth control pills for women who are breastfeeding because the mini-pill does not affect milk production. The most common progestin-only method used is the injectable depot medroxy-progesterone acetate which had been approved by Food and Drug Administration since 1992 . depot medroxy-progesterone acetate provides reliable, private, long-acting (three months) and reversible contraception. Users of depot medroxy-progesterone acetate don't need daily taking as well as it doesn't affect the intercourse by any mean. The etonogestrel implant (Implanon) is a single-rod progestin contraceptive method placed subdermally in the inner aspect of upper non dependant arm for three years. Much evidence supports the safety, efficacy, reversibility and acceptability of this contraceptive method. A common reason women choose to discontinue progestin-only contraception is dissatisfaction with its effects on uterine bleeding which occurs in a significant number of users. Information revealed from many clinical trials shows that abnormal uterine bleeding with progestin-only contraception ranging from 10 to 25 % at first year of use.
Background: The prevalence of repeat unprotected intercourse after EC use in the same cycle demonstrate the need for more self-bridging emergency contraceptive options. We propose the use of intramuscular Depot Medroxyprogesterone acetate (DMPA) as EC, which has been shown to inhibit follicular activity within 24 hours, and provide on-going contraception via suppression or disruption of ovulation. Objective: The objective of this study is to explore the potential of depot medroxyprogesterone acetate (DMPA) given as a 150-mg intramuscular injection for use as an emergency contraceptive. Study population: Healthy regularly menstruating women aged 18-39 years old will be invited to participate if they fulfill inclusion criteria. The participants will undergo a screening visit during the midluteal phase of their cycle, and will be enrolled if a serum progesterone level is >3ng/ml. Methodology: Participants will be assigned to one of three groups based on leading follicle size. Starting cycle Day 8, transvaginal ultrasounds will be performed to assess the size of the leading follicle. Once the follicle has reached the pre-assigned size, 150 mg IM DMPA will be administered. Blood will be collected for baseline hormonal assays. For 5 consecutive days, daily blood will be drawn for hormonal assays and daily transvaginal ultrasound will be performed to assess for signs of ovulation. The participant will then return for twice weekly progesterone levels for 2 weeks for study completion.
This is a multicenter observational study of implementation of postpartum contraceptive counseling and provision into the maternity care setting in Colombia, South America. The primary aim is to determine proportion of uptake of highly-effective contraceptive use after these methods become available immediately postpartum. Secondary aims include rapid repeat pregnancy rates, use of other types of contraception, breastfeeding continuation, and visualization of IUD strings after immediate postpartum placement.
Two-armed, single visit, pharmacokinetic study to compare tenofovir diphosphate concentrations in cervical tissues of women on Depo-Provera contraception vs non-hormonal contraception.
This study tests two posters that teach people about contraception: one designed by the Centers for Disease Control (CDC), and one designed by the researchers. The investigators hypothesize that the new poster will have more increased (1) contraceptive knowledge, (2) willingness to use effective contraception, and (3) perceived pregnancy risk than the CDC poster. This study will expand useful knowledge because contraceptive knowledge, willingness to use effective contraception, and perceived pregnancy risk have been shown to affect women's likelihood of using contraception. If the investigators learn how to increase these factors, the investigators could theoretically reduce women's risk of unplanned pregnancy. The investigators will test this hypothesis by recruiting N=1000 women to complete an online survey using Amazon Mechanical Turk. These women will complete a survey that will first measure their initial contraceptive knowledge, willingness to use effective contraception, and perceived pregnancy risk. Then women will randomly be shown one of the two posters. Then, the investigators will measure their contraceptive knowledge, willingness to use effective contraception, and perceived pregnancy risk again. The investigators will use statistical tests (a t-test) to find out whether there are significant changes in these three outcomes for either of the posters, and whether one poster does a better job of changing these outcomes than the other.
This trial evaluated folic acid supplementation after oral administration of the ethinyl estradiol + levonorgestrel + folic acid (0.02 mg + 0.10 mg + 0.4 mg) coated tablet (Level-Fol® Biolab Sanus Farmacêutica, São Paulo, Brazil) in healthy female volunteers, based on statistical comparisons of folate levels in erythrocytes. Its safety and tolerability was also evaluated.
This is an exploratory prospective study investigating if addition of a COX-2 inhibitor can increase efficacy of ulipristal in disrupting ovulation at peak fertility.
This study explores reasons why adolescents choose to receive a nexplanon implant and remove a Nexplanon implant. Nexplanon is provided as part of the standard of care on the University of Chicago mobile health unit. This study explores reasons for implantation and removal of Nexplanon on this mobile health unit.
A prospective, non-inferiority study to evaluate the pharmacokinetic effect of topiramate on serum Etonogestrel (ENG) levels in contraceptive implant users.
Data on the interaction between the etonogestrel (ENG) implant and antiepileptic drug (AED) regimen are scarce. We will evaluated the effect of 2 AED regimens (1 including carbamazepine and the other topiramate) on the pharmacokinetic (PK) parameters of an ENG-releasing implant in women with epilepsy.
