research Central 5-alpha reduction of testosterone is required for testosterone's inhibition of the hypothalamo-pituitary–adrenal axis response to restraint stress in adult male rats
Testosterone needs to be converted to DHT to reduce stress response in male rats.
research Effects of steroid hormones on the expression of Ca2+ activated K+ channels in in vitro pituitary cells of Atlantic cod (Gadus morhua)
Steroid hormones may affect sexual maturation in cod by altering certain KCa channel expressions.
research 562 Neuroendocrinology of human scalp hair follicles: Growth hormone-releasing hormone (GHRH) stimulates hair growth and controls a fully functional intrafollicular hypothalamic-pituitary-somatotropic (HPS) signaling axis
Growth hormone-releasing hormone (GHRH) boosts hair growth and human scalp hair follicles have their own growth hormone system.
research Hair Color, Molt, and Testis Size in Male, Short-Tailed Weasels Treated with Melatonin
Melatonin causes weasels to grow white fur and become reproductively inactive.
research Endocrine intervention for transsexuals
Hormone treatment for transsexual individuals is effective but carries risks like thromboembolic events and mood changes, with most side effects being minor and reversible.
research Current evaluation of amenorrhea
Amenorrhea is relatively rare and initial testing should check FSH, TSH, and prolactin levels.
research The clinical evaluation of hirsutism
Hirsutism is excessive hair growth in women often caused by polycystic ovarian syndrome, and identifying the cause is important for managing associated health risks.
research STEROIDS AND STEROID-LIKE COMPOUNDS
Athletes use steroids to enhance performance despite health risks and legal issues, and education on their dangers is needed.
research Does prolactin play a role in skin biology and pathology?
Prolactin may be important for skin growth and immune function.
research Studies of the components of an oral contraceptive agent in albino rats. I. Estrogenic component
High doses of ethynylestradiol in rats caused growth issues, organ changes, and some tumors, but didn't increase overall tumor rates.
research Hormonal Control of Pelage Cycles In The Mink
The pituitary gland is crucial for normal mink fur cycles.
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 THE ENDOCRINE SYSTEM AND HAIR GROWTH IN THE RAT
Male rats grow hair faster than females, and certain hormones can slow or slightly increase hair growth, but not significantly beyond natural rates.
research Fertility and sexual life of men after their forties and in older age.
Men's fertility and sexual health decline with age, with reduced testosterone and virility, and many lose fertility by their eighties.
research Androgen receptor in rat liver: Characterization and separation from a male-specific estrogen-binding protein
Male rats have androgen receptors in their liver, which are different from proteins that bind estrogen.
research EFFECTS OF ADRENOCORTICOTROPIC HORMONE ON BODY GROWTH, VISCERAL PROPORTIONS, AND WHITE BLOOD CELL COUNTS OF NORMAL AND HYPOPHYSECTOMIZED MALE RATS
Adrenocorticotropic hormone inhibits growth and affects body composition in male rats.
research Lesson of the week: Haemochromatosis as an endocrine cause of subfertility
Haemochromatosis can cause infertility by affecting hormone glands.
research HIRSUTISM IN FEMALES; A CLINICAL STUDY OF ITS ETIOLOGY, COURSE AND TREATMENT
Hirsutism in females is complex, often linked to tumors, and requires more research for better treatment.
research Netherton Syndrome Associated with Growth Hormone Deficiency
Growth hormone therapy can improve growth in Netherton syndrome patients with growth hormone deficiency.
research Regression of Pathologic Changes Induced by the Long-term Administration of Contraceptive Steroids to Rodents
Some steroid-induced health issues in rodents improved after stopping treatment, but hair loss and eye problems did not.
research COVID-19 and hypopituitarism
COVID-19 and hypopituitarism (reduced pituitary gland function) are linked, with the latter's related health issues potentially worsening COVID-19 outcomes, and COVID-19 possibly increasing risk for pituitary complications.
research Prolactin Signaling Influences the Timing Mechanism of the Hair Follicle: Analysis of Hair Growth Cycles in Prolactin Receptor Knockout Mice
Prolactin affects when mice shed and grow hair.
research Tertiary hypothyroidism in a dog
A dog with a pituitary tumor developed tertiary hypothyroidism, improved with treatment, but was later euthanized due to neurological issues.
research Molecular basis of androgen action on human sexual desire
Testosterone significantly affects sexual desire in both men and women, but its impact on women is more complex and influenced by psychological factors.
research Adenohypophysitis Associated with Sebaceous Gland Atrophy in a Dog
A dog had a rare skin condition linked to gland and pituitary issues.

Some sports supplements can cause health issues like mood swings, hair loss, and heart problems in men.
research Some Clues and Pitfalls in the Diagnosis of Acromegaly
Acromegaly can be hard to diagnose in young women with atypical symptoms, and persistent high phosphate levels should lead to growth hormone testing.
