A new humoral factor has been detected, within a project aiming to disclose the body's reproductive hormonal brake against tissue overgrowth, micrin ('my-crin'). Factor purification involved fractionation of ovine and bovine ovarian follicu…

Abstract Although the menstrual cycle is a vital sign for women’s health, research investigating menstrual cycle length (MCL) trajectories across reproductive life is scarce, often categorizing just two patterns: regular and irregular. We …

A new humoral factor has been detected, within a project aiming to disclose the body’s reproductive hormonal brake against tissue overgrowth, micrin (‘my-crin’). It is hypothesized that micrin braking, gonadal and hypothalamic, is lifted at…

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…

BACKGROUND: Solar ultraviolet radiation (UV) is a critical environmental factor for dermal conversion of vitamin D, which is suggested to support reproductive health. However, current epidemiological studies have reported conflicting result…

UNLABELLED: Previous studies have suggested noise, especially at night time, and light at night (LAN) could cause neuroendocrine disturbance and circadian disruption, which may lead to ovarian follicle atresia and earlier onset of menopause…

OBJECTIVE: To examine the association between ambient temperature and antral follicle count (AFC), a standard measure of ovarian reserve. DESIGN: Prospective cohort study. SETTING: Fertility center at an academic hospital in the northeast…

Evidence has shown associations between air pollution and traffic-related exposure with accelerated aging, but no study to date has linked the exposure with age at natural menopause, an important indicator of reproductive aging. In this stu…

STUDY QUESTION: Is there an association between air pollution exposures and incident infertility? SUMMARY ANSWER: Increased exposure to air pollution is associated with an increased incidence of infertility. WHAT IS KNOWN ALREADY: Exposur…

BACKGROUND: Particulate matter and proximity to large roadways may promote disease mechanisms, including systemic inflammation, hormonal alteration, and vascular proliferation, that may contribute to the development and severity of endometr…
