The failure rate of fertility awareness varies widely depending on the system used to identify fertile days, the instructional method, and the population being studied. Some studies have found actual failure rates of 25% per year or higher.
For avoiding pregnancy, the perfect-use failure rate of Creighton was 0.5%, which means that for each year that 1,000 couples using this method perfectly, that there are 5 unintended pregnancies. The typical-use failure rate, representing the fraction of couples using this method that actually had an unintended pregnancy, is reported as 3.2% ...
A woman whose menstrual cycles ranged in length from 30 to 36 days would be estimated to be infertile for the first 11 days of her cycle (30-19=11), to be fertile on days 12–25, and to resume infertility on day 26 (36-10=26). When used to avoid pregnancy, such fertility awareness-based methods have a typical-use failure rate of 25% per year. [18]
The impact factor (IF) or journal impact factor (JIF) of an academic journal is a scientometric index calculated by Clarivate that reflects the yearly mean number of citations of articles published in the last two years in a given journal, as indexed by Clarivate's Web of Science.
Comprehensive gynecological care can also help reduce the rates of HIV in minority women and increase contraceptive use. [7] The lack of reproductive health is a contributing factor in higher rates of maternal mortality in the United States among minority women, especially among Black women.
The journal is abstracted and indexed by the Science Citation Index Expanded, Scopus, MEDLINE, EMBASE, and PsycINFO.According to the Journal Citation Reports, the journal has a 2019 impact factor of 3.9, ranking it 9th out of 128 journals in the category "Pediatrics", [1] and 30th out of 193 journals in the category of "Public, Environmental and Occupational Health" (Sciences edition).
The failure rate of a copper IUD is approximately 0.8% and can prevent pregnancy for up to 10 years. The hormonal IUD (also known as levonorgestrel intrauterine system or LNg IUD) releases a small amount of the hormone called progestin that can prevent pregnancy for 3–8 years with a failure rate of 0.1-0.4%.

Adolescent health creates a major global burden and has a great deal of additional and diverse complications compared to adult reproductive health such as early pregnancy and parenting issues, difficulties accessing contraception and safe abortions, lack of healthcare access, and high rates of HIV, sexually transmitted infections and mental health issues.
