A paper published today in Biology of Reproduction's Papers-in-Press describes the effects of brief prenatal exposure to plant estrogens on the mouse oviduct, modeling the effects of soy-based baby formula on human infants. The results suggest that exposure to estrogenic chemicals in the womb or during childhood has the potential to affect a woman's fertility as an adult, possibly providing the mechanistic basis for some cases of unexplained female infertility. Earlier research suggested...

Girls who start puberty very early are more likely to have psychological problems and be at risk of sexual abuse and early pregnancy, suggests a new review published today (27 April) in The Obstetrician & Gynaecologist (TOG). Puberty is characterized by the maturation of the hypothalamic pituitary gonadal (HPG) axis, which plays a critical part in the development and regulation of the reproductive system. Normal puberty commences from approximately 10 years onwards and breast...

(Ivanhoe Newswire) -- Estrogen has a wide range of effects on the body and brain. The link between estrogen and emotion was first investigated over a century ago and showed that estrogen can improve mood. During PMS approximately 75% of reproductive-age women report premenstrual mood swings or physical discomfort. Women commonly feel depressed or grumpy during this time and brain scans have shown a significant increase in activity in the medial orbitofrontal cortex related to emotional...

Women's emotional responses can vary significantly premenstrually. They may become depressed or grumpy during menstruation or the premenstrual phase, known as premenstrual syndrome (PMS). Roughly 75% of reproductive-age women report premenstrual mood swings or physical discomfort. Brain scans show a significant increase in activity in the medial orbitofrontal cortex related to emotional processing premenstrually, even if women's emotional responses do not vary significantly. The relationship...

No clinical trials and no evidence of long-term safety, say authors Women who use bust-enhancing dietary supplements containing the mycoestrogen zearalenone (ZEN), a naturally occurring toxin that widely contaminates agricultural products, could be increasing their risk of breast cancer. That is the warning from breast health experts in a paper published online ahead of print publication in the January issue of IJCP, the International Journal of Clinical Practice. "No clinical trials...

Possible treatment options could result for diabetes, obesity and heart disease Hormone researchers at the University of Houston (UH) have their sights set on providing long-term treatment options for diabetes, obesity and cardiovascular diseases by better understanding estradiol, the most potent naturally occurring estrogen. They now believe that this estrogen hormone is a prominent regulator of several body functions in both females and males. While estradiol is more commonly...

University of Alberta researchers have identified a key regulator that controls the speed of development in the fruit fly. When the researchers blocked the function of this regulator, animals sped up their rate of development and reached maturity much faster than normal. The U of A research team, led by molecular geneticist Kirst King-Jones, noticed a peculiar behaviour of the protein they were studying, DHR4: The protein acted as a sentinel to either allow or prohibit the production of...
