This section brings together scientific studies, systematic reviews and academic publications that shed light on our topics: relationships, sexual and reproductive health, psychology, demography and family law.
Each selected study is presented with its publication date, authors or journal, a factual summary and a link to the scientific paper or the site page that explores the topic in depth.
— Three autumn 2026 studies shed new light on endometriosis: research in Reproductive BioMedicine Online identifies the enzyme pyruvate carboxylase as a metabolic driver of lesion invasion (opening a non-hormonal pathway), a cohort study in Human Reproduction tracks the persistent rise in antidepressant and anxiolytic prescriptions, and JOGC evaluates patient-specific 3D-printed surgical models.
— Presented at the 2026 American Society for Reproductive Medicine (ASRM) congress, the phase 3 SERENE trial in 981 women aged 18–35 shows that daily relugolix (40 mg), estradiol (1 mg) and norethindrone acetate (0.5 mg) provides effective contraception over 13 cycles, with a Pearl Index of 1.27.
— Published in Nature Communications on 16 October 2026, a randomized controlled trial using neonatal MRI scans shows that eight sessions of interpersonal psychotherapy for pregnant women experiencing psychological distress are associated with greater hippocampal volume growth in their infants.
— The University of Aberdeen is preparing a five-year, £2.3 million trial of a personalised twelve-week programme (medication, physiotherapy, psychological support) for women whose pain remains poorly relieved. Recruitment has not started and no results are known yet.
— Yale researchers compared lesions from 19 women with or without pain: nearly 900 genes are expressed differently, and an inflammatory molecule, IL16, is linked to the intensity of pain. This is basic research on a small group: no test or treatment results from it yet.
— A study published in Evolution and Human Behavior on 1 November 2026 shows that sexually satisfied single adults feel less urgency to enter a relationship and set higher standards for partnership quality. Meanwhile, the BLOOM theoretical model explains gender gaps in sexual pleasure through unequal adolescent learning opportunities.
— In its November 2026 issue, The Astrological eMagazine publishes a statistical evaluation of 85 classical astrological rules tested against 126 years of historical records (1900–2025): none performs better than chance once corrected for multiple comparisons, echoing large-scale demographic studies on zodiac compatibility in marriage.
— A study in Violence Against Women involving 896 young adults shows that while 76% had an opportunity to intervene as bystanders in non-consensual intimate image sharing, only 33% stepped in. Meanwhile, France's 2026 e-Enfance / 3018 Barometer reports that 32% of 6–18-year-olds have faced cyberbullying and 25% turn to AI chatbots for help.
— Published on 28 October 2026 in the European Journal of Population, a longitudinal study in the Netherlands following first-time parents shows that an unplanned pregnancy is associated with a 19% higher risk of parental separation before the child turns five, even after accounting for age, income and marital status.
— A Brigham Young University study of 1,693 young married American couples associates exercise done together, and also alone, with better communication and less conflict. The data, collected at a single point in time, do not show that exercise is the cause.
— A study in the Scandinavian Journal of Psychology, published online on 14 November 2025, looks at young adults who have been in a long-distance relationship for at least six months. Behaviours that maintain the relationship, especially openness and a positive attitude, are linked to greater mutual trust, itself linked to better relationship quality. These are statistical links, not proof of an effect.
— A study of 881 dating app users (Computers in Human Behavior, autumn 2026) reveals a paradox: transient loneliness reduces ghosting, whereas chronic loneliness increases it by triggering emotional dating app fatigue. Meanwhile, a systematic review of 21 studies (Encyclopedia MDPI, October 2026) finds that 64.5% of young adults have ghosted someone and 72% have been ghosted.
— Three studies by researchers at Berkeley and Cambridge (more than 1,100 participants) show that people who are ghosted underestimate how uncomfortable the other person feels, especially when the silence was not intended. A very short reply such as “sorry, can’t talk” is enough to reduce the misunderstanding.
— A study from Leuphana University of Lüneburg (543 participants responding to a fictional scenario, Journal of Social and Personal Relationships) compares three moments for sending a message after a first date: the next morning produces the highest relationship intentions; women appear more sensitive than men to this timing, close to the limit of statistical significance. These are reported intentions, not relationships followed over time.
— A study in Personality and Individual Differences involving 513 young adults in the United States and Turkey shows that perceived parental narcissism—especially vulnerable narcissism—is linked to higher depressive symptoms in adulthood through family enmeshment and reduced psychological flexibility.
— A study in Violence Against Women involving 896 young adults shows that while 76% had an opportunity to intervene as bystanders in non-consensual intimate image sharing, only 33% stepped in. Meanwhile, France's 2026 e-Enfance / 3018 Barometer reports that 32% of 6–18-year-olds have faced cyberbullying and 25% turn to AI chatbots for help.
