Researchers found that menstrual cramps were more severe and lasted longer in cycles without ovulation, challenging the long-held belief that cramps only occur during ovulatory cycles. The study of 75 women aged 19-35 showed that cycle lengths were the same, but anovulatory cycles had higher Cramp Scores
A third of trans masculine individuals taking testosterone are found to ovulate, according to a study from Amsterdam UMC's Center of Expertise on Gender Dysphoria. This discovery emphasizes the importance of birth control measures and comprehensive care for trans men who may experience unplanned pregnancy.

Researchers found that PTSD symptoms peak in women during the first few days of their menstrual cycle, when estradiol levels are low, and decrease near ovulation. This discovery could lead to more accurate diagnoses and treatments for women with PTSD, who have been underrepresented in previous research.
A team of researchers has developed a low-cost and low-waste device that uses Tootsie Roll candy as an electrode to monitor ovulation status or kidney health. The sensor works by detecting changes in salt levels in saliva, with preliminary tests showing promising results.

Researchers at Yale and Cincinnati Children's Hospital propose that the human female orgasm evolved to stimulate ovulation, a trait shared with many other placental mammals. The study suggests that female orgasm became superfluous for reproduction later in evolution, freeing it for secondary roles.
A study of wild female bonobos found that their sexual swellings are unreliable signals of fertility, allowing females to manipulate mate choice. The findings suggest that male bonobos may not be able to successfully compete over females due to the variability in swelling patterns.
Research found that female bonobos' unreliable sexual swellings make it difficult for males to time their mating efforts accurately. This may reduce aggressive mate competition and result in bonobo societies being more peaceful. The study advances understanding of the evolution of sexual signaling in our closest relatives.
Research finds women's faces increase in redness during ovulation, but levels are undetectable to the naked eye, challenging the idea that facial redness signals fertility; studies suggest other voluntary signals like make-up may have replaced involuntary ones
Researchers developed an ultra-superovulation method to increase the number of eggs obtained from genetically modified mice, reducing the need for multiple females and improving efficiency in IVF and embryo transfers. The breakthrough could lead to a significant reduction in the number of experimental animals used in research.

A study published in the Journal of Consumer Research found that ovulating women are more likely to choose multiple partners and products due to their increased fertility. This results in a greater variety seeking mindset, leading to a desire for new options in both personal relationships and consumer choices.
Research found that the average pregnancy length is 268 days, but variations of up to 37 days were detected. Factors such as a woman's age, birth weight, and previous pregnancies also influenced gestation duration.
Researchers have found that secretions from the reproductive tract contribute to both ovulation and sperm function, and that a specific hormone receptor gene controls this process. The study suggests that a similar mechanism may exist in mammals, providing new insights into the mechanisms of ovulation.
