Obesity was also linked to higher testosterone and lower estrogen levels, while moderate alcohol consumption reduced hot flash severity in some women.
Researchers at Yale University have discovered four genetic variants associated with spontaneous preterm birth in Hispanic women. The study found that mothers carrying these polymorphisms were significantly more likely to experience preterm birth. Notably, the ENPP1 variant was linked to the highest risk of preterm birth.
A new study by the March of Dimes Foundation finds that high-dose progesterone treatment can significantly reduce the risk of preterm delivery in pregnant women who have previously experienced premature labor. The treatment appeared to prevent cervical shortening and inflammation, key factors contributing to premature birth.
A study at NIMH found that brain reward circuit activity ebbs and flows with a woman's hormonal cycle. Women exhibited more active circuitry during the pre-ovulation phase dominated by estrogen compared to the post-ovulatory phase, suggesting links between hormone fluctuations and mood disorders.
UCI scientists discovered that mifepristone, a chemical compound used in abortion pills, can prevent breast tumor growth by inhibiting progesterone in breast tissue cells. This finding may lead to new prevention methods for women with a genetic predisposition to breast and ovarian cancers.
A study at Emory University Health Sciences Center found that giving progesterone to trauma victims shortly after a brain injury may reduce the risk of death and disability. The researchers also found a 50% reduction in death rate and significant improvement in functional outcome among patients who received progesterone.
A commercial progesterone therapy appears to prevent some premature births, with a 33% reduction in preterm birth rate for women who had a previous premature baby. The March of Dimes estimates that if all eligible women received the therapy, nearly 10,000 premature births might have been prevented.
Researchers at the University of Texas at Austin have discovered a link between estrogen, progesterone, and allergic responses in women. High levels of IgE antibodies against these hormones are associated with symptoms such as premenstrual asthma, menstrual migraines, and fibromyalgia.
The March of Dimes has awarded $2.4 million in grants to six innovative scientists working on new ways to identify women at increased risk for premature birth and understand the role of inflammation and progesterone in triggering labor. The goal is to prevent premature births, which are the leading cause of newborn death in the US.
The study found that the BRCA1 gene interacts with progesterone receptors to inhibit growth, but its absence leads to increased growth in response to estrogen and progestin. This understanding could lead to new treatment options for hormone-dependent cancers and ordinary cancers resulting from under-expressed BRCA1 genes.
A recent study published in The Journal of Clinical Pharmacology found that use of over-the-counter (OTC) topical progesterone results in significant drug exposure through skin absorption, comparable to prescribed oral progesterone products. The study revealed similar rates of adverse effects among women taking both types of progesterone.
Researchers at Cornell University found that higher-than-normal progesterone levels in female chickens during the first meiosis significantly produce more females. The study suggests that female birds manipulate sex ratios to adapt to their environment and ensure the next generation has enough females to care for.
Research reveals that female sex hormones, particularly estradiol, play a crucial role in defense against sexually transmitted diseases. Estradiol-treated mice showed 100% protection from herpes virus infection, while those with progesterone or no hormone showed extensive infection and increased inflammation.
