(Abstracted from JAMA 2024;332(6):482–489 Ovarian, breast, and endometrial cancers are known to be associated with endometriosis. This study was designed to assess associations between endometriosis and its subtypes with the overall inciden…

OBJECTIVES: To better understand whether history of infertility is associated with anti-Müllerian hormone (AMH) levels later in life, outside of reproduction. METHODS: Among 1,758 premenopausal women in the Nurses' Health Study II with mea…

BACKGROUND: There has been limited prior research on the association between infertility and risk of colorectal cancer. METHODS: Data from postmenopausal women in the Women's Health Initiative were used to estimate the association between …

BACKGROUND: Several studies have suggested an association between infertility and risk of endometrial cancer. However, most studies have evaluated this relationship in premenopausal people, yet the mean age of endometrial cancer is 60 years…

PURPOSE: Although infertility (i.e., failure to conceive after ≥ 12 months of trying) is strongly correlated with established breast cancer risk factors (e.g., nulliparity, number of pregnancies, and age at first pregnancy), its association…

OBJECTIVE: To determine whether endometriosis typology, namely ovarian endometriomas (OE), deep infiltrating endometriosis (DIE), or superficial endometriosis (SE), correlates with fertility history. DESIGN: Prospective cohort. SETTING: O…

OBJECTIVE: Anti-Müllerian hormone is a reliable measure of ovarian reserve associated with menopause timing and fertility. Previous studies have observed that individuals with endometriosis have lower anti-Müllerian hormone levels than thos…

Study questionWhat is the association between reproductive health history (e.g. age at menarche, menopause, reproductive lifespan) with abdominal adiposity in postmenopausal women?Summary answerHigher visceral adipose tissue (VAT) and subcu…

BACKGROUND: Chronic pelvic pain (CPP) is a multifactorial syndrome that can substantially affect a patient's quality of life. Endometriosis is one cause of CPP, and alterations of the immune and microbiome profiles have been observed in pat…

OBJECTIVE: To investigate barriers in accessing care for infertility in Mexico, because little is known about this issue for low and middle-income countries, which comprise 80% of the world's population. DESIGN: Cross-sectional analysis. …

OBJECTIVE: To investigate the association between infertility and the incidence of invasive cancer. DESIGN: Prospective cohort study (1989-2015). SETTING: Not applicable. PATIENT(S): A total of 103,080 women aged 25-42 years in the Nurse…

BACKGROUND: Women are at greater risk than men of developing chronic inflammatory conditions and "long COVID." However, few gynecologic health risk factors for long COVID-19 have been identified. Endometriosis is a common gynecologic disord…

OBJECTIVE: To describe the characteristics of people who experience changes to their menstrual cycle after COVID-19 vaccination. DESIGN: Longitudinal study. PATIENT(S): We recruited a volunteer sample with and without a history of SARS-Co…

PURPOSE: Research on infertility and risk of breast cancer has been conflicting, potentially because many well-established breast cancer risk factors, such as pregnancy history, are strongly correlated with infertility. METHODS: We followe…

Background: Hysterectomy, oophorectomy, and tubal ligation are common surgical procedures. The literature regarding cardiovascular disease (CVD) risk after these surgeries has focused on oophorectomy with limited research on hysterectomy or…

Background Certain symptoms associated with infertility are associated with cardiovascular disease, including menstrual cycle irregularity, early menopause, and obesity; however, few studies have investigated the association between inferti…

Female firefighters have occupational exposures which may negatively impact their reproductive health. Anti-müllerian hormone (AMH) is a clinical marker of ovarian reserve. We investigated whether AMH levels differed in female firefighters …

BACKGROUND: Despite anecdotal reports, the impacts of SARS-CoV-2 infection or COVID-19 vaccination on menstrual health have not been systemically investigated. OBJECTIVE: This study aimed to examine the associations of SARS-CoV-2 infection…

Numerous studies have demonstrated that assisted reproductive technology (ART: defined here as including only in vitro fertilization and related technologies) is associated with increased adverse pregnancy, neonatal, and childhood developme…

OBJECTIVE: To determine whether assisted reproductive technology (ART) treatment adds obstetric and neonatal risks over and above that of underlying infertility-related diagnoses. DESIGN: Retrospective study of linked ART, birth certificat…

IMPORTANCE: Early natural menopause (ENM) has been associated with reduced reproductive span, cardiovascular disease risk, and early mortality. The potential adverse implications of endometrioma surgery for ovarian reserve are known, yet th…

PURPOSE: Supraphysiologic serum estradiol levels may negatively impact the likelihood of conception and live birth following IVF. The purpose of this study is to determine if there is an association between serum estradiol level on the day …

OBJECTIVE: To investigate the association of infertility with atherosclerotic cardiovascular disease (ASCVD) among postmenopausal participants in the Women's Health Initiative (WHI). We hypothesized that nulliparity and pregnancy loss may r…

BACKGROUND: Infertility has been associated with common chronic non-communicable diseases. However, the association of infertility with long-term mortality is unclear. METHODS: We followed 101,777 women aged 25-42 years at enrollment betwe…
