Oocyte retrieval is possible for transgender men on testosterone therapy without affecting fertility outcomes.
research Squamous metaplasia of the prostate and diffuse alopecia in a 13-year-old castrated dog due to chronic ingestion of exogenous estradiol
A castrated dog developed hair loss and prostate issues from long-term exposure to estrogen cream.
research Advances of Stem Cell Therapeutics in Cutaneous Wound Healing and Regeneration
Stem cells show promise in speeding up wound healing and tissue regeneration.
research Delineation of Matriptase Protein Expression by Enzymatic Gene Trapping Suggests Diverging Roles in Barrier Function, Hair Formation, and Squamous Cell Carcinogenesis
Matriptase is crucial for skin barrier, hair growth, and may contribute to skin cancer.
research Endocrine Aspects of Female Sexual Dysfunction
Hormones like estrogen, testosterone, progesterone, and prolactin play complex roles in female sexual function, with testosterone potentially improving sexual desire, arousal, and satisfaction. However, more research is needed to establish safe and effective hormone treatments for female sexual dysfunction.
research Antioxidants in dermatology
Antioxidants can benefit skin health but should be used carefully to avoid negative effects.
research Biomaterials for in situ tissue regeneration: development and perspectives
Smart biomaterials that guide tissue repair are key for future medical treatments.
research Adverse effects of common medications on male fertility
Some common medications can harm male fertility, but many effects can be reversed.
research A clinical overview of hair removal using lasers and light sources
Lasers and light sources can effectively remove hair, work best on fair skin with dark hair, and usually need multiple treatments.
research Potential adverse effects of long-term testosterone therapy
Long-term testosterone therapy can cause hormone suppression, affect prostate and heart health, and alter physical characteristics, but does not increase prostate cancer risk and needs more research for full risk assessment.
research Resistance of degraded hair shafts to contaminant DNA
Degraded hair shafts resist contamination and can be easily cleaned.
research Genetic predictors of testosterone and their associations with cardiovascular disease and risk factors: A Mendelian randomization investigation
Testosterone is linked to cardiovascular risk factors and stroke, but its exact role is unclear.
research Exosomes mediate sensory hair cell protection in the inner ear
Exosomes are crucial for protecting sensory hair cells in the inner ear.
research The novel mechanisms and applications of exosomes in dermatology and cutaneous medical aesthetics
Exosomes can improve skin health and offer new treatments for skin repair and rejuvenation.
research Testosterone therapy for sexual dysfunction in postmenopausal women
Testosterone therapy can help improve sexual desire and function in postmenopausal women but may cause side effects and is not FDA-approved for this use.
research Lack of androgen receptor transcriptional activity in human keratinocytes
Human keratinocytes do not naturally respond to androgens.
research Current evaluation of amenorrhea
Amenorrhea is when a woman doesn't have periods, with primary amenorrhea starting by age 15 or within five years of breast development, and secondary amenorrhea when periods stop for three months. It affects 3-4% of women not pregnant, breastfeeding, or in menopause, mainly due to polycystic ovary syndrome, hypothalamic amenorrhea, hyperprolactinemia, and ovarian failure.
research Postmenopausal virilization after spousal use of topical androgens
A woman developed male traits from accidental contact with her husband's testosterone gel.
research The hair eclipse phenomenon: sharpening the focus on the hair cycle chronobiology
Hair growth and shedding are linked and can be disrupted, causing a delay known as the hair eclipse phenomenon, which is common in certain hair conditions and could lead to new treatments.
research Characterization of hair lipid images by argon sputter etching-scanning electron microscopy
Hair texture changes with age due to varying levels of lipids.
research Cheating on forensic hair testing? Detection of potential biomarkers for cosmetically altered hair samples using untargeted hair metabolomics
Researchers found markers that can tell if hair has been bleached, which could improve hair test accuracy.
research Effect of testosterone on chests and abdomens of transgender men
Testosterone increases hair growth and acne in transgender men.
