Artemisinins, plant-based antimalarials, may serve as a treatment for polycystic ovary syndrome - which affects millions of women worldwide and can lead to infertility - according to a new study published in Science. The compounds suppressed ovarian androgen production in rodents, as well as in a small cohort of 19 human patients for 12 weeks, leading to more regular menstrual cycles without side effects. 


Research published in JAMA Network Open indicates that women with premenstrual disorders diagnosed before the age of 25 have a higher risk of all-cause mortality and death by suicide. For death by suicide, the risk increased regardless of age at diagnosis. However, in general, women with premenstrual disorders do not have an increased risk of premature death from natural and unnatural causes. The study compares over several years a group of more than 67,000 women in Sweden with a diagnosed disorder with a group of more than 338,000 women without such a diagnosis. 

ovarian cycle

The ovarian cycle is regulated by internal circadian rhythms rather than external processes, says a study published in Science Advances. Using menstrual cycle data from some 3,000 women in Europe and North America, the authors add that the influence of the lunar cycle on women's menstrual cycle is weak, but significant.


Dressing in school uniform is associated with less physical activity in children, especially primary school girls, according to a study by the University of Cambridge (UK) published in the Journal of Sport and Health Science. The study analysed data on the physical activity levels of more than one million children aged 5-17 in 135 countries, including Spain, combined with an online survey.


Results from a survey of more than 39,000 menstruating individuals reveal that 42% experienced heavier bleeding after SARS-CoV-2 vaccination. Among the most likely groups were pre-menopausal women, Hispanic or Latina women, those who had been pregnant, and those with conditions such as endometriosis and polycystic ovary syndrome.
