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.
A study of nearly 4,000 women found that respiratory symptoms like wheezing, shortness of breath, and cough change throughout the menstrual cycle, varying by body mass index, asthma, and smoking status. These patterns suggest a link between hormonal changes and respiratory symptoms through the menstrual cycle.
A new UCLA study reveals that women in stable but not-so-sexy relationships become more distant and critical during periods of high fertility, according to researchers. Despite this, the negative feelings appear fleeting and do not impact long-term commitment to their romantic relationship.
Researchers found that ovulation rates and quality remained unchanged after bariatric surgery, with only a minor shortening of the menstrual cycle. Weight loss improved sexual function, particularly desire and arousal, in obese women seeking pregnancy.
Researchers from Inserm unit 693 have discovered that hyperprolactinaemia directly inhibits the secretion of kisspeptin, a neurohormone essential for GnRH release and ovarian cyclicity. Administering kisspeptin can restore ovulation function in women with hyperprolactinaemia.
Research by UTSA College of Business professor Kristina Durante reveals that women's perceptions of men as potential fathers are influenced by hormonal fluctuations during ovulation. Women tend to overestimate the domestic contributions of sexy cads and underestimate those of reliable dads.
A new study published in PLOS ONE challenges the idea that women's voices contain cues for men to detect ovulation. The researchers found that the variation in women's vocal quality throughout the menstrual cycle does not provide reliable information about the timing of ovulation, making it a poor mating clue.
The ClearBlue Digital Ovulation test accurately predicts ovulation in 99% of women, surpassing the calendar method's accuracy rate of one in four.
Researchers found that women can more accurately identify straight vs gay men's faces near peak ovulation, with mating goals enhancing accuracy further.
Researchers at the Weizmann Institute discovered that antioxidants can cause a decrease in ovulation levels in female mice, potentially disrupting fertility. The study suggests that reactive oxygen species play a crucial role in the ovulation process and may be affected by antioxidant supplementation.
A new study in the Journal of Consumer Research found that ovulating women choose sexier fashion products when thinking about other attractive local women. This unconscious behavior is driven by a desire to outdo rivals and entice desirable mates.
A new study published in Psychological Science found that men's testosterone levels increase when exposed to scents from women who are ovulating. The research suggests that this response may promote mating-related behavior in males. This study provides direct evidence of the influence of olfactory cues on male biological responses.
Researchers at Baylor College of Medicine found that extracellular signal-regulated kinases (ERK1 and ERK2) are essential for ovulation, oocyte maturation, and other key activities in ovarian function. Disrupting the activity of both enzymes was necessary to block fertility in female mammals.
The study reveals that ERK1 and ERK2 proteins trigger a chain of chemical sequences that bring about the release of the egg, transformation of granulosa cells into luteal cells, and production of progesterone. The finding has implications for treating infertility and developing new means to prevent pregnancy.
A new study from Indiana University's Kinsey Institute explores the link between hormone levels and brain responses to masculinized versus feminized male faces. The research found that neural activation in response to face stimuli is sensitive to facial masculinization, with differences appearing strongest during the follicular phase c...
Scientists have identified a gene called Lrh1 that plays a crucial role in regulating ovulation. Deleting this gene in mice prevents ovulation, opening up potential avenues for developing more effective contraceptives and fertility treatments. This discovery could benefit up to 15% of infertile couples seeking help.
Researchers at Indiana University found that women's brains respond differently to male faces depending on the menstrual cycle stage. During ovulation, their brains show more activity in areas related to rewards and less activity in areas associated with inhibition. Additionally, training has been shown to improve balance in older adul...
PCOS is characterized by multiple health complications, including menstrual dysfunction, infertility, hirsutism, and metabolic syndrome. Research focuses on identifying the primary cause of PCOS, which may be linked to defects in the ovary, hypothalamic-pituitary axis, or abnormal insulin activity.
Researchers found that standard treatment with clomiphene was more effective than metformin alone in helping women with PCOS achieve successful pregnancy. The study, the largest and most comprehensive effort yet to compare the two drugs, showed that obese women were less likely to conceive during the course of the study.
Research finds standard therapy more effective in helping women with PCOS achieve pregnancy compared to diabetes drug metformin, which was initially thought to have great promise. Clomiphene fosters ovulation by stimulating hormone release, increasing pregnancy chances two times over metformin.
A study found that cognitive behavioural therapy can restore ovulation in infertile women by reducing cortisol levels and improving the hypothalamic-pituitary-thyroid axis. The therapy was effective in reversing stress-induced ovulation, offering a cost-effective and safe alternative to hormonal treatments.
New research at the University of Liverpool has found that men sense a preference shift in their female partners and find masculine men more threatening during their most fertile phase. Men only behave this way if their female partner does not use oral contraception and is therefore more fertile.
Researchers at NIEHS discovered that the beta estrogen receptor plays a significant role in ovarian function, potentially leading to new treatments for infertility. A simple blood test could diagnose genetic mutations affecting the receptor's function, improving treatment options and chances of having a healthy child.
Researchers created a mouse model with increased cAMP levels in eggs, leading to infertility. By blocking another protein, egg maturation was completed, revealing potential new contraceptive targets.
Research found that women's intercourse frequency increased during fertile days, peaking at ovulation. The study of 68 women over three months showed a 24% increase in intercourse during fertile days compared to the rest of the cycle.
Researchers studied 87 women with epilepsy and found that nearly 40% experience catamential patterns where seizures fluctuate with menstrual cycles. Progesterone lozenges may help reduce seizure frequency and severity during monthly hormonal changes.
Researchers found that gingival inflammation decreases during menstruation compared to ovulation and premenstruation. The hormone estradiol may play a role in this phenomenon, according to the study published by the American Academy of Periodontology.
Research found that aging brains reduce ovulation in women, leading to decreased fertility. The study suggests that high oestrogen levels and decreased LH release contribute to this effect.
Researchers studied over 1000 pregnant women from diverse countries and found no significant link between optimal timing of conception and lower birth defect rates. The findings are reassuring for natural family planning users and those with infrequent or sporadic sexual activity.
A US-Italian study found that women's fertility starts declining before age 30, but not necessarily their overall chance of pregnancy. Meanwhile, men's fertility also begins to decline in their late 30s, but the duration of the fertile window remains unchanged.
Research with monkeys shows that low energy availability due to strenuous exercise training causes amenorrhea. Increasing food intake reverses the effect, suggesting a key role for energy balance in exercise-induced amenorrhea.
Researchers developed a new algorithm called TwoDay, which uses vaginal dampness as a predictor of fertility. Women can reduce pregnancy risk by avoiding unprotected sex for 2 days after noticing vaginal dampness.
Researchers found that women taking oral contraceptives showed no change in their ability to detect odors, compared to the natural clime of the luteal phase. The study suggests that iatrogenic steroids may affect changes in smell sensitivity, and further research is needed to investigate this phenomenon.
Researchers found that most women (70%) are in their fertile window before day 10 or after day 17, leaving few universal 'safe' days for natural birth control. The study also revealed that late ovulation can occur even in women with regular cycles, increasing the chances of pregnancy during the fifth week.
Researchers found a strong link between increased ovulatory cycles and p53 genetic mutations in ovarian cancer. Women at high risk can protect themselves by reducing their ovulation through birth control, pregnancy, or breast-feeding.
