Hibiscus plant extracts may have health benefits like lowering blood pressure and protecting the heart.
research Reproductive Seasonality and Maturation Throughout the Complete Life-Cycle in the Mouflon Ram (Ovis Musimon)
Mouflon rams mature gradually with changes in body, horns, and hormones linked to age and seasons, reaching full sexual maturity well after puberty.
research Congenital Adrenal Hyperplasia: A Comprehensive Review
The document concludes that early diagnosis and treatment of Congenital Adrenal Hyperplasia are crucial for preventing serious health issues and improving patient outcomes.
research Steroidogenesis of the Testis: New Genes and Pathways
New genes and pathways are important for testosterone production and male sexual development.
research Male Gonadal Function in Coeliac Disease: Sex Hormones
Men with coeliac disease may have hormone imbalances that could affect sexual function, but these can improve with better gut health.
research Perspectives of Kennedy's Disease
Kennedy's disease leads to muscle weakness and sensory issues, has no cure but manageable symptoms, and future treatments look promising.
research 46,XY DSD Due to Impaired Androgen Production
Impaired androgen production in 46,XY DSDs causes ambiguous genitalia and requires long-term care.
research Endocrine Disorders in Woodhouse-Sakati Syndrome: A Systematic Review of the Literature

research Adverse Health Effects of Androgen Use
Using anabolic androgenic steroids can cause serious, lasting health problems in many parts of the body.
research Emerging Concepts About Prenatal Genesis, Aberrant Metabolism, and Treatment Paradigms in Polycystic Ovary Syndrome
PCOS may start before birth, involves metabolic issues, and can be treated with drugs like metformin and lifestyle changes.
research Association Between Testicular Microlithiasis and Primary Malignancy of the Testis: Our Experience and Review of the Literature
Testicular microlithiasis may increase the risk of testicular cancer and patients with it should be closely monitored.
research A Case of Familial Male-Limited Precocious Puberty with a Novel Mutation
A boy with a rare form of early puberty caused by a new gene mutation responded well to treatment aimed at reducing testosterone and preserving adult height.
research Hormones
Hormones are crucial for regulating body functions and imbalances can lead to health issues.
research Spontaneous Fertility in a Male Patient with Testotoxicosis Despite Suppression of FSH Levels
A man with testotoxicosis was fertile despite low FSH levels, suggesting high testosterone may allow sperm production without FSH.
research Unusual Presentation of Denys-Drash Syndrome in a Girl with Undisclosed Consumption of Biotin
A girl with Denys-Drash syndrome was misdiagnosed due to biotin affecting her hormone test results.
