The Investigation of Vitamin D and Menstrual Cycles Trial (the inVitD Trial): A clinical trial of vitamin D supplementation on the hypothalamic-pituitary-ovarian axis
Contemporary clinical trials ·doi:10.1016/j.cct.2025.108176

BACKGROUND: While there is evidence that vitamin D deficiency is associated with long menstrual cycles, delayed ovulation, and reduced fertility, it is yet unknown if increasing vitamin D levels can regulate menstrual cycles, and thus possi…

The independent and joint associations of hysterectomy and uterine fibroids or endometriosis with ovarian cancer incidence: results from a US-based cohort
American journal of epidemiology ·doi:10.1093/aje/kwae235

Uterine fibroids and endometriosis may be associated with an increased risk of ovarian cancer. Less is known about the role of hysterectomy in these associations. We estimated the independent and joint associations of hysterectomy, fibroids…

Association of Fibroids, Endometriosis, and Gynecologic Surgeries with Breast Cancer Incidence and Hormone Receptor Subtypes
Cancer epidemiology, biomarkers & prevention : a publication of the American Association for Cancer Research, cosponsored by the American Society of Preventive Oncology ·doi:10.1158/1055-9965.epi-23-1014

BACKGROUND: Fibroids and endometriosis are sex hormone-mediated and exhibit cancer-like behavior. Breast cancer may be more common in women who have had these conditions, but the literature is conflicting and does not always address factors…
