A survey of 1,068 parents aged 13-17 found that more than half supported parental notification laws (PNLs), which allow minors to obtain birth control without parental consent. Parents' support for PNLs may stem from fears about unknown others making decisions on their children's health.
A new study has found that teenaged women who stop using Depo-Provera experience significant gains in bone density compared to those still taking the contraceptive. The research suggests that continuous use of Depo-Provera leads to a loss of bone mass, which appears to be reversible once the drug is discontinued.
Researchers found that women who experience vision loss during a migraine are 70% more likely to have a stroke. Migraines without visual symptoms do not significantly increase stroke risk. The study's findings suggest that women with migraines and aura should address other stroke risk factors, such as smoking.
A study found that 60% of minors reported a parent or guardian was aware of their clinic visits, while 59% would still use the clinic for prescription contraception even with parental notification. The researchers also discovered that 18% of teenagers would engage in risky sexual behavior if parental involvement were mandated.
Researchers found that women who received emergency contraception (EC) through pharmacies or advance provision were more likely to use EC than those with clinic access. Despite concerns about increased risk-taking and STIs, the study revealed no significant differences in pregnancy rates or STI acquisition between groups.

This suggests a potential link between birth month and reproductive performance, with possible explanations including environmental factors and early developmental influences.
A University of Pittsburgh study found that providing young women with emergency contraceptive pills at home did not lead to an increase in unprotected sex or inconsistent contraceptive use. Instead, the study showed a corresponding increase in condom use among those who received the pills.
A new study found that the birth control patch had a higher percentage of perfect dosing cycles (88.7%) compared to oral contraceptives (79.2%). This led to better contraceptive efficacy and reduced risk of unplanned pregnancy. The results suggest that the patch may be a more convenient and simple option for women using birth control.
A study of 92 patient cases found that laparoscopy can diagnose abnormalities earlier, reducing the need for hormone therapy and in vitro fertilization. Women with painful menstrual periods, previous natural contraception use, or a history of pelvic disorders are at higher risk.
Researchers identified a gene that plays a critical role in sperm cell hyperactivation, which is essential for fertilization. Disrupting this protein could render sperm cells ineffective or infertile, leading to a new type of fast-acting and low-side-effect contraceptive.

The researchers emphasize the importance of integrating mind and body discussions to meet teens' comprehensive needs.
A UK study found no overall increased risk of death among women who used oral contraceptives, suggesting a potential lower mortality rate compared to non-users. Smoking was associated with a higher risk of death from all causes, particularly in heavy smokers.
Researchers found that the ThinPrep Pap test was more likely to detect abnormal cervical cells in women taking oral contraceptives than those not on birth control. In reality, most healthy cells looked like HPV-infected cells due to changes caused by the testing method, highlighting the need for further analysis and potential re-testing.
A new six-month study investigates continuous combined oral contraception for its potential to prevent periods easily and safely. The study hopes to show whether breakthrough bleeding ceases in women taking this new regimen.
A recent study by French researchers found that nearly two-thirds of unplanned pregnancies occurred among women using effective contraception methods like the Pill and IUD. The study suggests that there is often a mismatch between a woman's contraceptive needs and the methods she uses.
A new study found that current low-dose oral contraceptives significantly increase plasma concentrations of C-reactive protein (CRP), an inflammatory biomarker associated with cardiovascular disease. CRP levels were two times higher among OC users than non-users, regardless of diet assignment or phase of the menstrual cycle.
Researchers found that women who used oral contraceptives for over 5 years were at a significantly higher risk of developing cervical cancer. The study analyzed data from 28 studies and found that the relative risk of cervical cancer increased with increasing duration of use, with risks doubling after 10 years.
A postnatal home-visiting service for teenage mothers aged under 18 years was shown to reduce adverse health outcomes of their children, including infant deaths and foster care placements. Home visits also increased mothers' contraceptive use, but not breastfeeding or vaccination knowledge.
A new study published by Georgetown University Medical Center found a link between worsening epileptic seizures and estrogen intake in women. Approximately 20% of women with epilepsy experienced seizures worsened when using estrogen-containing oral contraceptives.
A randomized trial found that a single dose of 1.5 mg levonorgestrel is as effective as traditional regimens for emergency contraception, with no significant differences in pregnancy rates or side-effects. The new regimen simplifies use and reduces side effects, allowing women to begin regular contraception sooner.
A study found that long-term oral contraceptive use is associated with a 33% increase in breast cancer risk among women with BRCA1 mutations, particularly those who started using contraceptives before age 30. In contrast, no significant increase in breast cancer risk was observed in women with BRCA2 mutations.
