Thyroid hormones and androgens affect gene expression in frog reproductive organs differently between males and females.

Bisphenol-A (BPA) increases connections between brain cells and boosts their activity, but it blocks the effects of a male hormone on brain cell plasticity.

The document concludes that sex hormones are crucial for mammalian reproduction, health, and behavior, and require more research for therapeutic use.

Women generally handle heart enlargement better than men, but it's riskier for them if it occurs; hormones like estrogen offer some protection.

Men are more likely to have severe COVID-19 cases and fatalities than women due to factors like lifestyle, aging, and biological differences.

Men and women get COVID-19 at similar rates, but men tend to get sicker and have a higher risk of dying, while women usually have stronger immune responses and vaccine reactions.

Androgen therapy can help with symptoms like low libido in women, but more research is needed to understand its long-term safety and effects on health.

Finasteride may affect female fertility by altering gene activity.

Testosterone is important for men's sexual function, may help some women's sexual desire, while other hormones and neurotransmitters also play complex roles in sexual behavior.

Tranexamic acid effectively reduced swelling episodes in a girl with a rare form of hereditary angioneurotic edema.

Improving blood flow and oxygen levels in middle age may help prevent age-related diseases.

The androgen receptor is a promising target for breast cancer treatment, especially in triple-negative cases, but more research is needed for personalized therapies.

PROTACs show promise for cancer treatment, but designing them effectively is challenging.

Females generally have stronger immune responses than males due to the X chromosome.

Estrogen is important for keeping adult mouse nipple skin healthy by controlling certain cell signals.

Estrogen therapy can reduce skin aging but has cancer risks.

Rare adrenal cancers that secrete androgens or estrogens have a poor prognosis and are treated primarily with surgery.

The study concluded that both estrogen and androgen receptors, which decrease with age, are linked to skin aging and may be hormonally regulated.

Certain gene patterns in breast cancer are linked to how active hormone receptors are and could affect patient survival.

Using 5-alpha reductase inhibitors may lower the risk of breast cancer in females.

Estrogen and androgen signals control synaptic changes in rat brains.

Estrogen loss during menopause worsens skin health, but hormone replacement therapy may improve it, though more research is needed.

Estrogens help reduce skin aging, and SERMs might offer similar benefits without the risks of hormone therapy.

The three estrogen receptor genes are highly expressed in zebrafish neuromasts during development.

Vitamin D and estrogen may help protect heart and kidney health, and maintaining sufficient vitamin D levels could be especially beneficial for African Americans, postmenopausal women, and people with chronic kidney disease.

Honokiol might help reduce male skin aging by maintaining testosterone levels.

Timosaponin BII, a plant extract, was found to promote hair growth in mice, similarly to minoxidil.

Topical estrogen treatments did not change hair growth in certain mouse strains, questioning previous findings on their role in hair growth control.

The document explains how to create detailed biological pathways using genomic data and tools, with examples of hair and breast development.

The effects of estrogen on human hair growth are unclear and need more research.
