Taking biotin can lead to incorrect low results in free testosterone tests.

Testosterone therapy can modestly improve sexual function in menopausal women but should be used cautiously and is not recommended for routine measurement in sexual dysfunction or hirsutism.

Hair analysis can somewhat track past testosterone levels but is influenced by factors like hair washing, growth rate, sex, and hair color.

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

Steroid hormones can be preserved in ancient hair, revealing insights into past health and fertility.

Testosterone increases 3α-androstanediol levels, which can be blocked by finasteride.

The S9 fraction with GC-IDMS is effective for measuring 5α-reductase activity.

The new LC-MS/MS method is more accurate and reliable than traditional immunoassays for measuring steroids in serum.

A new method was created to test the effectiveness of Dihydrotestosterone (DHT) inhibitors, like finasteride and dutasteride, in human and fish cells. The results showed fish cells are more sensitive to these treatments, and dutasteride works better than finasteride in all tested cells.

Androgenetic alopecia in teens is linked to obesity and other metabolic risks, needing early diagnosis and management.

The guidelines suggest reconsidering PCOS criteria for better diagnosis and care.

Advancements in male reproductive medicine are ongoing, but more research and improved treatments are needed in several areas.

Women with PCOS have higher androgen levels that decrease with age but are still higher than in women without PCOS.

Red deer only have androgen receptors in neck hair cells for mane growth during breeding season.

Testosterone significantly affects urination differences between male and female mice.

False high testosterone levels were corrected using a more accurate test.

The study created a new method to test drugs that affect hormone processing in skin.

The new test can measure very small amounts of testosterone in hair, and grinding the hair up first gives more accurate results.

Cinnamomi cortex may help treat prostate enlargement by reducing related proteins.

Compounds 4, 4b, and 4c effectively inhibit an enzyme linked to testosterone conversion without significant toxicity.

High testosterone levels in 20% of the women studied may indicate PCOS, while 80% had low levels with potential health impacts.

New testosterone analogs show promise for male contraception with better activity and potentially fewer side effects.

Black pepper leaf extract contains compounds that can block testosterone effects and promote hair growth.

Testosterone affects androgen receptors and lipid storage in cells, while DHEA does not convert to testosterone or affect these receptors in the same way.

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

DHEA is the main sex steroid in cerebrospinal fluid, and testosterone in the fluid comes from the blood.

The Endocrine Society advised against routine testosterone therapy for women, citing a need for more research on long-term safety and a clear definition of androgen deficiency.

Sickle cell anemia causes hormone issues and delayed puberty due to testicular failure.
