Objective: To evaluate the cost-effectiveness of a novel intrauterine system, levonorgestrel intrauterine system 13.5 mg vs. oral contraception, in women at risk of unintended pregnancy.

Design: Cost-effectiveness model using efficacy and discontinuation data from published articles.

Setting: Societal perspective including direct and indirect costs.

Population: Women at risk of unintended pregnancy using reversible contraception.

Methods: An economic analysis was conducted by modeling the different health states of women using contraception over a 3-year period. Typical use efficacy rates from published articles were used to determine unintended pregnancy events. Discontinuation rates were used to account for method switching.

Main Outcome Measures: Cost-effectiveness was evaluated in terms of the incremental cost per unintended pregnancy avoided. In addition, the incremental cost per quality-adjusted life-year was calculated.

Results: Levonorgestrel intrauterine system 13.5 mg generated costs savings of € 311,000 in a cohort of 1000 women aged 15-44 years. In addition, there were fewer unintended pregnancies (55 vs. 294) compared with women using oral contraception.

Conclusion: Levonorgestrel intrauterine system 13.5 mg is a cost-effective method when compared with oral contraception. A shift in contraceptive use from oral contraception to long-acting reversible contraception methods could result in fewer unintended pregnancies, quality-adjusted life-year gains, as well as cost savings.

The prevalence of artificial reproductive technologies (ART), such as intra-uterine insemination (IUI), fertilization (IVF), and intracytoplasmic sperm injection (ICSI), has surged in response to the global increase in infertility rates, now impacting 17.5 % of couples. With over nine million babies born through ART, the safety and efficacy of these methods are largely recognized; however, emerging concerns regarding their association with prenatal and long-term health risks, especially cardiovascular disease (CVD), necessitate a thorough examination.

Nicotine is one of the most toxic substances found in cigarettes, but also found in chewing tobacco gum, patches and vaping products (electronic cigarettes). In addition to being a highly addictive chemical, it is capable of reducing fertility in men and women. In the ovaries, it can induce morphological changes and impair the formation of follicles, being a possible cause of changes in the reproductive cycle and anticipation of menopause in women whose mothers smoked during pregnancy.

Background: Intrauterine growth restriction (IUGR) is a severe condition in which the fetus fails to reach its genetically predetermined growth potential, impairing prenatal development and predisposing individuals to postnatal consequences that may persist into adulthood. Although fetal mechanisms such as the brain-sparing effect have been proposed to protect the brain against IUGR-related deficits, the extent of this protection remains unclear.

Objective: To conduct a systematic review that demonstrates prenatal morphofunctional abnormalities in the brain of individuals with IUGR.
