Menopause causes significant changes in the vaginal introitus, but less so in the labia majora, which may lead to symptoms of vaginal atrophy.

Blocking androgen activity in newborn rats affects body weight and appetite-related hormones differently in males and females.

Ursolic acid can shrink the prostate and lower a hormone linked to prostate growth in rats.

The conclusion is that proper signaling is crucial for hair growth and development, and errors can lead to cancer or hair loss.

Wnt/beta-catenin signaling in the skin helps fat cell development during hair growth and repair.

Androgens are important for normal ovarian function and estrogen production, but may not be the main cause of follicle death.

Most adrenal cortex tumors are benign and non-secreting, but proper diagnosis and treatment are important due to the rare possibility of cancer.

Certain genes may influence hair loss differently in men and women.

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.

Oestrogen and thyrotropin-releasing hormone affect prolactin and its receptor in human skin and hair, suggesting new treatment options for related conditions.

Sex and stress steroids quickly change brain cell structures in the hippocampus.

PDGFA/AKT signaling is important for the growth and maintenance of certain skin fat cells.

Prolactin affects when mice shed and grow hair.

Wnt signaling is crucial for skin and hair development and its disruption can cause skin tumors.

mTOR signaling helps activate hair stem cells by balancing out the suppression caused by BMP during hair growth.

Androgens slow hair growth by altering Wnt signaling in balding cells.

Hormones during pregnancy and lactation keep skin stem cells inactive, preventing hair growth.

Tannic acid helps wounds heal faster in rats by activating certain cell signals and reducing inflammation.

Skin aging is caused by stem cell damage and can potentially be delayed with treatments like antioxidants and stem cell therapy.

Researchers developed a mouse model that tracks hair growth using bioluminescence, improving accuracy in studying hair cycles.

Prolactin affects when mice shed and grow hair.

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.

Certain gene variants in estrogen receptors are linked to polycystic ovary syndrome, mainly affecting metabolism, in Tunisian women.

HPV genes and estradiol increase a cancer-related signaling pathway, which may be targeted for cervical cancer treatment.

Estrogen and androgenic hair increase melanoma risk, especially in European-ancestry individuals.

Females have higher estrogen receptor levels in hair than males, and these levels decrease in white hair compared to black hair.

Activating β-catenin in certain skin cells speeds up hair growth in mice.

Hair aging is caused by stress, hormones, inflammation, and DNA damage affecting hair growth and color.
