Objective: To estimate the effect of contraception on fertility in the border region of Chiapas, Mexico.
Materials And Methods: In 1994 an epidemiological cross-sectional study was carried out on a representative sample of 1,560 non-indigenous women between ages 15 and 49 in the border region of Chiapas. The prevalence of contraception practices and the total fertility rates (TFR) were obtained and stratified by rural, intermediate and urban communities. TFR were compared between women who had never used contraceptives and those who had used them.
Results: The estimated TFR was 3.67 and varied from 4.14 in rural areas to 3.36 in urban areas. There were no differences in the TFR (3.74 and 3.88) nor in the average live births (3.47 and 3.48) between women who had never used contraceptives and those who had used them.
Conclusions: The major effect of contraception on fertility was observed in rural areas. Factors which influence the small impact of contraception on fertility include the late use of these methods and the early age of first union among users.

Unlike high-grade serous carcinoma (HGSC), which mainly affects postmenopausal women, mucinous ovarian carcinoma (MOC) affects younger patients, with a median age at diagnosis of 53 years, and is rare among premenopausal women. After they receive anticancer treatment, these women encounter specific issues involving fertility preservation (FP) and/or pregnancy, which potentially require assisted reproductive technology (ART) as well as the prescription of hormonal contraception (HC) or hormone replacement therapy (HRT). We reviewed the available literature in PubMed/Medline concerning the risks of the development of ovarian cancer (OC), including MOC, associated with ART, HC and HRT, and literature on the impact of ovarian stimulation in the context of FP and/or ART, HC and HRT in women previously treated for OC, including MOC.

Background: Reproductive coercion (RC) is a type of abuse where a partner intentionally attempts to interfere with fertility through deception or violence, often by manipulating one's contraceptive use or reproductive decision-making. Cross-sectional studies on the magnitude of RC across sub-Saharan Africa have noted associations with contraceptive use. No studies have longitudinally examined RC experiences as related to future contraceptive dynamics, including discontinuation or forgoing use altogether.
