21-hydroxylase deficiency causes hormone imbalances leading to various symptoms, and diagnosis involves clinical and genetic tests.

Free Testosterone Index, bioavailable testosterone, and androstenedione are the most accurate for diagnosing excess male hormones in PCOS.

Finasteride effectively lowers specific hormone levels, helping monitor treatment progress.

New genes and pathways are important for testosterone production and male sexual development.

A new method was developed to analyze certain hormones and drugs in human blood efficiently.

Hair samples can reliably show average long-term hormone levels in young women.

A new method accurately measures long-term hormone levels in hair.

DHT inhibition may increase spinal bone growth in ankylosing spondylitis.

Altered DHEA metabolism in hair follicles may be linked to hair loss in balding men.

DPP may help hair regrowth by improving blood vessel function under stress.

Women with androgenetic alopecia have normal levels of most blood steroids and binding proteins, but higher dehydroepiandrosterone. Some also have low "sex hormone-binding globulin" and "corticosteroide-binding globulin" capacity, and high "free androgen index" and "free cortisol index". Diane treatment can normalize these levels and improve hair conditions.

The chemicals 17βC and its methyl ester can block the effects of testosterone on hamster skin but not the effects of DHT.

Diane and Androcur 10 improved acne and seborrhea in most women, and hirsutism and alopecia in about half.

Androgen levels increase with puberty and are linked to sexual hair development.

Obesity changes androgen levels in women with PCOS, leading to higher testosterone relative to androstenedione.

Estrogen increases blood vessel growth factor production, while testosterone blocks this increase.

The update highlights that non-classic congenital adrenal hyperplasia is common in women with excess male hormones, requires specific hormone tests for diagnosis, and has various treatment options depending on age and symptoms.

The method accurately measures certain steroids in human hair, showing different levels in males and females.

Certain adrenal hormones can strongly stimulate oil gland growth in hamster skin, similar to male hormones.

The guidelines advise against using testosterone and DHEA in women for most conditions due to safety and effectiveness concerns, but suggest considering testosterone for postmenopausal women with low sexual desire.

Certain finger length ratios and body hair patterns may predict side effects from birth control pills in women.

3α-androstanediol helps reduce age-related cognitive and mood declines in male rats, unlike testosterone.

Higher DHEA-S levels in hirsute females affect hair growth phases.

Bolandiol, a synthetic steroid, builds muscle and bone without greatly affecting sex glands, and works differently from other hormones.

Women with non-classical congenital adrenal hyperplasia have higher levels of certain steroids, which can be reduced by treatment.

Over half of the adult women with acne in the study had higher than normal levels of male hormones, especially DHEA.

3βHSD2 is not useful for diagnosing PCOS.

Androgens, male hormones, play a role in both men and women's health, and testosterone therapy can help women with low levels, but it's not suitable for pregnant or lactating women, or those with certain conditions.

The assay effectively detects hormonal activity of certain chemicals.

Antiandrogens and finasteride may help treat excess hair and hair loss in women.
